+
+This README is [also available in a friendly navigable format](http://devise.plataformatec.com.br/).
+
+Devise is a flexible authentication solution for Rails based on Warden. It:
+
+* Is Rack based;
+* Is a complete MVC solution based on Rails engines;
+* Allows you to have multiple models signed in at the same time;
+* Is based on a modularity concept: use only what you really need.
+
+It's composed of 10 modules:
+
+* [Database Authenticatable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/DatabaseAuthenticatable): encrypts and stores a password in the database to validate the authenticity of a user while signing in. The authentication can be done both through POST requests or HTTP Basic Authentication.
+* [Omniauthable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Omniauthable): adds OmniAuth (https://github.com/intridea/omniauth) support.
+* [Confirmable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Confirmable): sends emails with confirmation instructions and verifies whether an account is already confirmed during sign in.
+* [Recoverable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Recoverable): resets the user password and sends reset instructions.
+* [Registerable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Registerable): handles signing up users through a registration process, also allowing them to edit and destroy their account.
+* [Rememberable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Rememberable): manages generating and clearing a token for remembering the user from a saved cookie.
+* [Trackable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Trackable): tracks sign in count, timestamps and IP address.
+* [Timeoutable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Timeoutable): expires sessions that have not been active in a specified period of time.
+* [Validatable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Validatable): provides validations of email and password. It's optional and can be customized, so you're able to define your own validations.
+* [Lockable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Lockable): locks an account after a specified number of failed sign-in attempts. Can unlock via email or after a specified time period.
+
+Devise is guaranteed to be thread-safe on YARV. Thread-safety support on JRuby is in progress.
+
+## Information
+
+### The Devise wiki
+
+The Devise Wiki has lots of additional information about Devise including many "how-to" articles and answers to the most frequently asked questions. Please browse the Wiki after finishing this README:
+
+https://github.com/plataformatec/devise/wiki
+
+### Bug reports
+
+If you discover a problem with Devise, we would like to know about it. However, we ask that you please review these guidelines before submitting a bug report:
+
+https://github.com/plataformatec/devise/wiki/Bug-reports
+
+If you have discovered a security related bug, please do *NOT* use the GitHub issue tracker. Send an email to opensource@plataformatec.com.br.
+
+### Mailing list
+
+If you have any questions, comments, or concerns, please use the Google Group instead of the GitHub issue tracker:
+
+https://groups.google.com/group/plataformatec-devise
+
+### RDocs
+
+You can view the Devise documentation in RDoc format here:
+
+http://rubydoc.info/github/plataformatec/devise/master/frames
+
+If you need to use Devise with previous versions of Rails, you can always run "gem server" from the command line after you install the gem to access the old documentation.
+
+### Example applications
+
+There are a few example applications available on GitHub that demonstrate various features of Devise with different versions of Rails. You can view them here:
+
+https://github.com/plataformatec/devise/wiki/Example-Applications
+
+### Extensions
+
+Our community has created a number of extensions that add functionality above and beyond what is included with Devise. You can view a list of available extensions and add your own here:
+
+https://github.com/plataformatec/devise/wiki/Extensions
+
+### Contributing
+
+We hope that you will consider contributing to Devise. Please read this short overview for some information about how to get started:
+
+https://github.com/plataformatec/devise/wiki/Contributing
+
+You will usually want to write tests for your changes.  To run the test suite, go into Devise's top-level directory and run "bundle install" and "rake".  For the tests to pass, you will need to have a MongoDB server (version 2.0 or newer) running on your system.
+
+## Starting with Rails?
+
+If you are building your first Rails application, we recommend you *do not* use Devise. Devise requires a good understanding of the Rails Framework. In such cases, we advise you to start a simple authentication system from scratch. Today we have two resources that should help you get started:
+
+* Michael Hartl's online book: https://www.railstutorial.org/book/modeling_users
+* Ryan Bates' Railscast: http://railscasts.com/episodes/250-authentication-from-scratch
+
+Once you have solidified your understanding of Rails and authentication mechanisms, we assure you Devise will be very pleasant to work with. :smiley:
+
+## Getting started
+
+Devise 3.0 works with Rails 3.2 onwards. You can add it to your Gemfile with:
+
+```ruby
+gem 'devise'
+```
+
+Run the bundle command to install it.
+
+After you install Devise and add it to your Gemfile, you need to run the generator:
+
+```console
+rails generate devise:install
+```
+
+The generator will install an initializer which describes ALL of Devise's configuration options. It is *imperative* that you take a look at it. When you are done, you are ready to add Devise to any of your models using the generator:
+
+```console
+rails generate devise MODEL
+```
+
+Replace MODEL with the class name used for the application’s users (it’s frequently `User` but could also be `Admin`). This will create a model (if one does not exist) and configure it with default Devise modules. The generator also configures your `config/routes.rb` file to point to the Devise controller.
+
+Next, check the MODEL for any additional configuration options you might want to add, such as confirmable or lockable. If you add an option, be sure to inspect the migration file (created by the generator if your ORM supports them) and uncomment the appropriate section.  For example, if you add the confirmable option in the model, you'll need to uncomment the Confirmable section in the migration. Then run `rake db:migrate`
+
+Next, you need to set up the default URL options for the Devise mailer in each environment. Here is a possible configuration for `config/environments/development.rb`:
+
+```ruby
+config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
+```
+
+You should restart your application after changing Devise's configuration options. Otherwise, you will run into strange errors, for example, users being unable to login and route helpers being undefined.
+
+### Controller filters and helpers
+
+Devise will create some helpers to use inside your controllers and views. To set up a controller with user authentication, just add this before_action (assuming your devise model is 'User'):
+
+```ruby
+before_action :authenticate_user!
+```
+
+If your devise model is something other than User, replace "_user" with "_yourmodel". The same logic applies to the instructions below.
+
+To verify if a user is signed in, use the following helper:
+
+```ruby
+user_signed_in?
+```
+
+For the current signed-in user, this helper is available:
+
+```ruby
+current_user
+```
+
+You can access the session for this scope:
+
+```ruby
+user_session
+```
+
+After signing in a user, confirming the account or updating the password, Devise will look for a scoped root path to redirect to. For instance, when using a `:user` resource, the `user_root_path` will be used if it exists; otherwise, the default `root_path` will be used. This means that you need to set the root inside your routes:
+
+```ruby
+root to: "home#index"
+```
+
+You can also override `after_sign_in_path_for` and `after_sign_out_path_for` to customize your redirect hooks.
+
+Notice that if your Devise model is called `Member` instead of `User`, for example, then the helpers available are:
+
+```ruby
+before_action :authenticate_member!
+
+member_signed_in?
+
+current_member
+
+member_session
+```
+
+### Configuring Models
+
+The Devise method in your models also accepts some options to configure its modules. For example, you can choose the cost of the encryption algorithm with:
+
+```ruby
+devise :database_authenticatable, :registerable, :confirmable, :recoverable, stretches: 20
+```
+
+Besides `:stretches`, you can define `:pepper`, `:encryptor`, `:confirm_within`, `:remember_for`, `:timeout_in`, `:unlock_in` among other options. For more details, see the initializer file that was created when you invoked the "devise:install" generator described above. This file is usually located at `/config/initializers/devise.rb`.
+
+### Strong Parameters
+
+When you customize your own views, you may end up adding new attributes to forms. Rails 4 moved the parameter sanitization from the model to the controller, causing Devise to handle this concern at the controller as well.
+
+There are just three actions in Devise that allows any set of parameters to be passed down to the model, therefore requiring sanitization. Their names and the permitted parameters by default are:
+
+* `sign_in` (`Devise::SessionsController#create`) - Permits only the authentication keys (like `email`)
+* `sign_up` (`Devise::RegistrationsController#create`) - Permits authentication keys plus `password` and `password_confirmation`
+* `account_update` (`Devise::RegistrationsController#update`) - Permits authentication keys plus `password`, `password_confirmation` and `current_password`
+
+In case you want to permit additional parameters (the lazy way™), you can do so using a simple before filter in your `ApplicationController`:
+
+```ruby
+class ApplicationController < ActionController::Base
+  before_action :configure_permitted_parameters, if: :devise_controller?
+
+  protected
+
+  def configure_permitted_parameters
+    devise_parameter_sanitizer.for(:sign_up) << :username
+  end
+end
+```
+
+The above works for any additional fields where the parameters are simple scalar types. If you have nested attributes (say you're using `accepts_nested_attributes_for`), then you will need to tell devise about those nestings and types. Devise allows you to completely change Devise defaults or invoke custom behaviour by passing a block:
+
+To permit simple scalar values for username and email, use this
+
+```ruby
+def configure_permitted_parameters
+  devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :email) }
+end
+```
+
+If you have some checkboxes that express the roles a user may take on registration, the browser will send those selected checkboxes as an array. An array is not one of Strong Parameters' permitted scalars, so we need to configure Devise in the following way:
+
+```ruby
+def configure_permitted_parameters
+  devise_parameter_sanitizer.for(:sign_up) { |u| u.permit({ roles: [] }, :email, :password, :password_confirmation) }
+end
+```
+For the list of permitted scalars, and how to declare permitted keys in nested hashes and arrays, see
+
+https://github.com/rails/strong_parameters#nested-parameters
+
+If you have multiple Devise models, you may want to set up a different parameter sanitizer per model. In this case, we recommend inheriting from `Devise::ParameterSanitizer` and adding your own logic:
+
+```ruby
+class User::ParameterSanitizer < Devise::ParameterSanitizer
+  def sign_in
+    default_params.permit(:username, :email)
+  end
+end
+```
+
+And then configure your controllers to use it:
+
+```ruby
+class ApplicationController < ActionController::Base
+  protected
+
+  def devise_parameter_sanitizer
+    if resource_class == User
+      User::ParameterSanitizer.new(User, :user, params)
+    else
+      super # Use the default one
+    end
+  end
+end
+```
+
+The example above overrides the permitted parameters for the user to be both `:username` and `:email`. The non-lazy way to configure parameters would be by defining the before filter above in a custom controller. We detail how to configure and customize controllers in some sections below.
+
+### Configuring views
+
+We built Devise to help you quickly develop an application that uses authentication. However, we don't want to be in your way when you need to customize it.
+
+Since Devise is an engine, all its views are packaged inside the gem. These views will help you get started, but after some time you may want to change them. If this is the case, you just need to invoke the following generator, and it will copy all views to your application:
+
+```console
+rails generate devise:views
+```
+
+If you have more than one Devise model in your application (such as `User` and `Admin`), you will notice that Devise uses the same views for all models. Fortunately, Devise offers an easy way to customize views. All you need to do is set `config.scoped_views = true` inside the `config/initializers/devise.rb` file.
+
+After doing so, you will be able to have views based on the role like `users/sessions/new` and `admins/sessions/new`. If no view is found within the scope, Devise will use the default view at `devise/sessions/new`. You can also use the generator to generate scoped views:
+
+```console
+rails generate devise:views users
+```
+
+If you would like to generate only a few sets of views, like the ones for the `registerable` and `confirmable` module,
+you can pass a list of modules to the generator with the `-v` flag.
+
+```console
+rails generate devise:views -v registrations confirmations
+```
+
+### Configuring controllers
+
+If the customization at the views level is not enough, you can customize each controller by following these steps:
+
+1. Create your custom controllers using the generator which requires a scope:
+
+    ```console
+    rails generate devise:controllers [scope]
+    ```
+
+    If you specify `users` as the scope, controllers will be created in `app/controllers/users/`.
+    And the sessions controller will look like this:
+
+    ```ruby
+    class Users::SessionsController < Devise::SessionsController
+      # GET /resource/sign_in
+      # def new
+      #   super
+      # end
+      ...
+    end
+    ```
+
+2. Tell the router to use this controller:
+
+    ```ruby
+    devise_for :users, controllers: { sessions: "users/sessions" }
+    ```
+
+3. Copy the views from `devise/sessions` to `users/sessions`. Since the controller was changed, it won't use the default views located in `devise/sessions`.
+
+4. Finally, change or extend the desired controller actions.
+
+    You can completely override a controller action:
+
+    ```ruby
+    class Users::SessionsController < Devise::SessionsController
+      def create
+        # custom sign-in code
+      end
+    end
+    ```
+
+    Or you can simply add new behaviour to it:
+
+    ```ruby
+    class Users::SessionsController < Devise::SessionsController
+      def create
+        super do |resource|
+          BackgroundWorker.trigger(resource)
+        end
+      end
+    end
+    ```
+
+    This is useful for triggering background jobs or logging events during certain actions.
+
+Remember that Devise uses flash messages to let users know if sign in was successful or unsuccessful. Devise expects your application to call `flash[:notice]` and `flash[:alert]` as appropriate. Do not print the entire flash hash, print only specific keys. In some circumstances, Devise adds a `:timedout` key to the flash hash, which is not meant for display. Remove this key from the hash if you intend to print the entire hash.
+
+### Configuring routes
+
+Devise also ships with default routes. If you need to customize them, you should probably be able to do it through the devise_for method. It accepts several options like :class_name, :path_prefix and so on, including the possibility to change path names for I18n:
+
+```ruby
+devise_for :users, path: "auth", path_names: { sign_in: 'login', sign_out: 'logout', password: 'secret', confirmation: 'verification', unlock: 'unblock', registration: 'register', sign_up: 'cmon_let_me_in' }
+```
+
+Be sure to check `devise_for` documentation for details.
+
+If you have the need for more deep customization, for instance to also allow "/sign_in" besides "/users/sign_in", all you need to do is to create your routes normally and wrap them in a `devise_scope` block in the router:
+
+```ruby
+devise_scope :user do
+  get "sign_in", to: "devise/sessions#new"
+end
+```
+
+This way, you tell Devise to use the scope `:user` when "/sign_in" is accessed. Notice `devise_scope` is also aliased as `as` in your router.
+
+### I18n
+
+Devise uses flash messages with I18n, in conjunction with the flash keys :notice and :alert. To customize your app, you can set up your locale file:
+
+```yaml
+en:
+  devise:
+    sessions:
+      signed_in: 'Signed in successfully.'
+```
+
+You can also create distinct messages based on the resource you've configured using the singular name given in routes:
+
+```yaml
+en:
+  devise:
+    sessions:
+      user:
+        signed_in: 'Welcome user, you are signed in.'
+      admin:
+        signed_in: 'Hello admin!'
+```
+
+The Devise mailer uses a similar pattern to create subject messages:
+
+```yaml
+en:
+  devise:
+    mailer:
+      confirmation_instructions:
+        subject: 'Hello everybody!'
+        user_subject: 'Hello User! Please confirm your email'
+      reset_password_instructions:
+        subject: 'Reset instructions'
+```
+
+Take a look at our locale file to check all available messages. You may also be interested in one of the many translations that are available on our wiki:
+
+https://github.com/plataformatec/devise/wiki/I18n
+
+Caution: Devise Controllers inherit from ApplicationController. If your app uses multiple locales, you should be sure to set I18n.locale in ApplicationController.
+
+### Test helpers
+
+Devise includes some test helpers for functional specs. In order to use them, you need to include Devise in your functional tests by adding the following to the bottom of your `test/test_helper.rb` file:
+
+```ruby
+class ActionController::TestCase
+  include Devise::TestHelpers
+end
+```
+
+If you're using RSpec, you can put the following inside a file named `spec/support/devise.rb` or in your `spec/spec_helper.rb` (or `spec/rails_helper.rb` if you are using rspec-rails):
+
+```ruby
+RSpec.configure do |config|
+  config.include Devise::TestHelpers, type: :controller
+end
+```
+
+Just be sure that this inclusion is made *after* the `require 'rspec/rails'` directive.
+
+Now you are ready to use the `sign_in` and `sign_out` methods. Such methods have the same signature as in controllers:
+
+```ruby
+sign_in :user, @user   # sign_in(scope, resource)
+sign_in @user          # sign_in(resource)
+
+sign_out :user         # sign_out(scope)
+sign_out @user         # sign_out(resource)
+```
+
+There are two things that are important to keep in mind:
+
+1. These helpers are not going to work for integration tests driven by Capybara or Webrat. They are meant to be used with functional tests only. Instead, fill in the form or explicitly set the user in session;
+
+2. If you are testing Devise internal controllers or a controller that inherits from Devise's, you need to tell Devise which mapping should be used before a request. This is necessary because Devise gets this information from the router, but since functional tests do not pass through the router, it needs to be stated explicitly. For example, if you are testing the user scope, simply use:
+
+    ```ruby
+    @request.env["devise.mapping"] = Devise.mappings[:user]
+    get :new
+    ```
+
+You can read more about testing your Rails 3 - Rails 4 controllers with RSpec in the wiki:
+
+* https://github.com/plataformatec/devise/wiki/How-To:-Test-controllers-with-Rails-3-and-4-%28and-RSpec%29
+
+### OmniAuth
+
+Devise comes with OmniAuth support out of the box to authenticate with other providers. To use it, simply specify your OmniAuth configuration in `config/initializers/devise.rb`:
+
+```ruby
+config.omniauth :github, 'APP_ID', 'APP_SECRET', scope: 'user,public_repo'
+```
+
+You can read more about OmniAuth support in the wiki:
+
+* https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview
+
+### Configuring multiple models
+
+Devise allows you to set up as many Devise models as you want. If you want to have an Admin model with just authentication and timeout features, in addition to the User model above, just run:
+
+```ruby
+# Create a migration with the required fields
+create_table :admins do |t|
+  t.string :email
+  t.string :encrypted_password
+  t.timestamps null: false
+end
+
+# Inside your Admin model
+devise :database_authenticatable, :timeoutable
+
+# Inside your routes
+devise_for :admins
+
+# Inside your protected controller
+before_filter :authenticate_admin!
+
+# Inside your controllers and views
+admin_signed_in?
+current_admin
+admin_session
+```
+
+Alternatively, you can simply run the Devise generator.
+
+Keep in mind that those models will have completely different routes. They **do not** and **cannot** share the same controller for sign in, sign out and so on. In case you want to have different roles sharing the same actions, we recommend that you use a role-based approach, by either providing a role column or using a dedicated gem for authorization.
+
+### ActiveJob Integration
+
+If you are using Rails 4.2 and ActiveJob to deliver ActionMailer messages in the
+background through a queuing back-end, you can send Devise emails through your
+existing queue by overriding the `send_devise_notification` method in your model.
+
+```ruby
+def send_devise_notification(notification, *args)
+  devise_mailer.send(notification, self, *args).deliver_later
+end
+```
+
+### Password reset tokens and Rails logs
+
+If you enable the [Recoverable](http://rubydoc.info/github/plataformatec/devise/master/Devise/Models/Recoverable) module, note that a stolen password reset token could give an attacker access to your application. Devise takes effort to generate random, secure tokens, and stores only token digests in the database, never plaintext. However the default logging behavior in Rails can cause plaintext tokens to leak into log files:
+
+1. Action Mailer logs the entire contents of all outgoing emails to the DEBUG level. Password reset tokens delivered to users in email will be leaked.
+2. Active Job logs all arguments to every enqueued job at the INFO level. If you configure Devise to use `deliver_later` to send password reset emails, password reset tokens will be leaked.
+
+Rails sets the production logger level to DEBUG by default. Consider changing your production logger level to WARN if you wish to prevent tokens from being leaked into your logs. In `config/environments/production.rb`:
+
+```ruby
+config.log_level = :warn
+```
+
+
+### Other ORMs
+
+Devise supports ActiveRecord (default) and Mongoid. To select another ORM, simply require it in the initializer file.
+
+## Additional information
+
+### Heroku
+
+Using Devise on Heroku with Ruby on Rails 3.2 requires setting:
+
+```ruby
+config.assets.initialize_on_precompile = false
+```

-== Devise
-
-Devise is a flexible authentication solution for Rails based on Warden. It:
-
-* Is Rack based;
-* Is a complete MVC solution based on Rails engines;
-* Allows you to have multiple roles (or models/scopes) signed in at the same time;
-* Is based on a modularity concept: use just what you really need.
-
-It's composed of 12 modules:
-
-* Database Authenticatable: encrypts and stores a password in the database to validate the authenticity of a user while signing in. The authentication can be done both through POST requests or HTTP Basic Authentication.
-* Token Authenticatable: signs in a user based on an authentication token (also known as "single access token"). The token can be given both through query string or HTTP Basic Authentication.
-* Omniauthable: adds Omniauth (github.com/intridea/omniauth) support;
-* Confirmable: sends emails with confirmation instructions and verifies whether an account is already confirmed during sign in.
-* Recoverable: resets the user password and sends reset instructions.
-* Registerable: handles signing up users through a registration process, also allowing them to edit and destroy their account.
-* Rememberable: manages generating and clearing a token for remembering the user from a saved cookie.
-* Trackable: tracks sign in count, timestamps and IP address.
-* Timeoutable: expires sessions that have no activity in a specified period of time.
-* Validatable: provides validations of email and password. It's optional and can be customized, so you're able to define your own validations.
-* Lockable: locks an account after a specified number of failed sign-in attempts. Can unlock via email or after a specified time period.
-* Encryptable: adds support of other authentication mechanisms besides the built-in Bcrypt (the default).
-

-=== RDocs
-
-You can view the Devise documentation in RDoc format here:
-
-http://rubydoc.info/github/plataformatec/devise/master/frames
-
-If you need to use Devise with Rails 2.3, you can always run `gem server` from the command line after you install the gem to access the old documentation.
-
-=== Example applications
-
-There are a few example applications available on GitHub that demonstrate various features of Devise with different versions of Rails. You can view them here:
-
-http://github.com/plataformatec/devise/wiki/Example-Applications
-
-=== Extensions
-
-Our community has created a number of extensions that add functionality above and beyond what is included with Devise. You can view a list of available extensions and add your own here:
-
-http://github.com/plataformatec/devise/wiki/Extensions
-
-=== Contributing
-
-We hope that you will consider contributing to Devise. Please read this short overview for some information about how to get started:
-
-http://github.com/plataformatec/devise/wiki/Contributing
-
-You will usually want to write tests for your changes.  To run the test suite, `cd` into Devise's top-level directory and run `bundle install` and `rake`.  For the tests to pass, you will need to have a MongoDB server (version 1.6 or newer) running on your system.
-
-== Installation
-
-You can use the latest Rails 3 gem with the latest Devise gem:
-
-  gem install devise
-
-After you install Devise and add it to your Gemfile, you need to run the generator:
-
-  rails generate devise:install
-
-The generator will install an initializer which describes ALL Devise's configuration options and you MUST take a look at it. When you are done, you are ready to add Devise to any of your models using the generator:
-
-  rails generate devise MODEL
-
-Replace MODEL by the class name you want to add devise, like User, Admin, etc. This will create a model (if one does not exist) and configure it with default Devise modules. The generator will also create a migration file (if your ORM support them) and configure your routes. Continue reading this file to understand exactly what the generator produces and how to use it.
-
-Support for Rails 2.3.x can be found by installing Devise 1.0.x from the v1.0 branch.
-
-== Starting with Rails?
-
-If you are building your first Rails application, we recommend you to *not* use Devise. Devise requires a good understanding of the Rails Framework. In such cases, we advise you to start a simple authentication system from scratch, today we have two resources:
-
-* Michael Hartl's online book: http://railstutorial.org/chapters/modeling-and-viewing-users-two#top
-* Ryan Bates' Railscast: http://railscasts.com/episodes/250-authentication-from-scratch
-
-Once you have solidified you understanding of Rails and authentication mechanisms, we assure you Devise will be very pleasant to work with. :)
-
-== Getting started
-
-This is a walkthrough with all steps you need to setup a devise resource, including model, migration, route files, and optional configuration.
-
-Devise must be set up within the model (or models) you want to use. Devise routes must be created inside your config/routes.rb file.
-
-We're assuming here you want a User model with some Devise modules, as outlined below:
-
-  class User < ActiveRecord::Base
-    devise :database_authenticatable, :confirmable, :recoverable, :rememberable, :trackable, :validatable
-  end
-
-After you choose which modules to use, you need to set up your migrations. Luckily, Devise has some helpers to save you from this boring work:
-
-  create_table :users do |t|
-    t.database_authenticatable
-    t.confirmable
-    t.recoverable
-    t.rememberable
-    t.trackable
-    t.timestamps
-  end
-
-Devise doesn't use _attr_accessible_ or _attr_protected_ inside its modules, so be sure to define attributes as accessible or protected in your model.
-
-Configure your routes after setting up your model. Open your config/routes.rb file and add:
-
-  devise_for :users
-
-This will use your User model to create a set of needed routes (you can see them by running `rake routes`). If you invoked the devise generator, you noticed that this is exactly what the generator produces for us: model, routes and migrations.
-
-Don't forget to run rake db:migrate and you are ready to go! But don't stop reading here, we still have a lot to tell you.
-
-=== Controller filters and helpers
-
-Devise will create some helpers to use inside your controllers and views. To set up a controller with user authentication, just add this before_filter:
-
-  before_filter :authenticate_user!
-
-To verify if a user is signed in, use the following helper:
-
-  user_signed_in?
-
-For the current signed-in user, this helper is available:
-
-  current_user
-
-You can access the session for this scope:
-
-  user_session
-
-After signing in a user, confirming the account or updating the password, Devise will look for a scoped root path to redirect. Example: For a :user resource, it will use user_root_path if it exists, otherwise default root_path will be used. This means that you need to set the root inside your routes:
-
-  root :to => "home"
-
-You can also overwrite after_sign_in_path_for and after_sign_out_path_for to customize your redirect hooks.
-
-Finally, you need to set up default url options for the mailer in each environment. Here is the configuration for config/environments/development.rb:
-
-  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
-
-Notice that if your devise model is not called "user" but "member", then the helpers you should use are:
-
-  before_filter :authenticate_member!
-
-  member_signed_in?
-
-  current_member
-
-  member_session
-
-=== Configuring Models
-
-The devise method in your models also accepts some options to configure its modules. For example, you can choose which encryptor to use in database_authenticatable:
-
-  devise :database_authenticatable, :confirmable, :recoverable, :stretches => 20
-
-Besides :stretches, you can define :pepper, :encryptor, :confirm_within, :remember_for, :timeout_in, :unlock_in and other values. For details, see the initializer file that was created when you invoked the "devise:install" generator described above.
-
-=== Configuring multiple models
-
-Devise allows you to set up as many roles as you want. For example, you may have a User model and also want an Admin model with just authentication, trackable, lockable and timeoutable features and no confirmation or password-recovery features. Just follow these steps:
-
-  # Create a migration with the required fields
-  create_table :admins do |t|
-    t.database_authenticatable
-    t.lockable
-    t.trackable
-    t.timestamps
-  end
-
-  # Inside your Admin model
-  devise :database_authenticatable, :trackable, :timeoutable, :lockable
-
-  # Inside your routes
-  devise_for :admins
-
-  # Inside your protected controller
-  before_filter :authenticate_admin!
-
-  # Inside your controllers and views
-  admin_signed_in?
-  current_admin
-  admin_session
-
-=== Configuring views
-
-We built Devise to help you quickly develop an application that uses authentication. However, we don't want to be in your way when you need to customize it.
-
-Since Devise is an engine, all its views are packaged inside the gem. These views will help you get started, but after sometime you may want to change them. If this is the case, you just need to invoke the following generator, and it will copy all views to your application:
-
-  rails generate devise:views
-
-Devise currently supports generating views for the following template engines (use the `-e` flag for the devise:views generator):
-
-* Erb
-* Haml (http://github.com/nex3/haml)
-* Slim (http://github.com/stonean/slim)
-
-Note: If you are generating Haml or Slim templates, you will need to have a few dependencies such as `ruby_parser` (for Haml), `hpricot` (for both Haml and Slim) and `haml2slim` (for Slim) installed.
-
-If you have more than one role in your application (such as "User" and "Admin"), you will notice that Devise uses the same views for all roles. Fortunately, Devise offers an easy way to customize views. All you need to do is set "config.scoped_views = true" inside "config/initializers/devise.rb".
-
-After doing so, you will be able to have views based on the role like "users/sessions/new" and "admins/sessions/new". If no view is found within the scope, Devise will use the default view at "devise/sessions/new". You can also use the generator to generate scoped views:
-
-  rails generate devise:views users
-
-=== Configuring controllers
-
-If the customization at the views level is not enough, you can customize each controller by following these steps:
-
-1) Create your custom controller, for example a Admins::SessionsController:
-
-    class Admins::SessionsController < Devise::SessionsController
-    end
-
-2) Tell the router to use this controller:
-
-    devise_for :admins, :controllers => { :sessions => "admins/sessions" }
-
-3) And since we changed the controller, it won't use the "devise/sessions" views, so remember to copy "devise/sessions" to "admin/sessions".
-
-Remember that Devise uses flash messages to let users know if sign in was successful or failed. Devise expects your application to call "flash[:notice]" and "flash[:alert]" as appropriate.
-
-=== Configuring routes
-
-Devise also ships with default routes. If you need to customize them, you should probably be able to do it through the devise_for method. It accepts several options like :class_name, :path_prefix and so on, including the possibility to change path names for I18n:
-
-  devise_for :users, :path => "usuarios", :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification', :unlock => 'unblock', :registration => 'register', :sign_up => 'cmon_let_me_in' }
-
-Be sure to check devise_for documentation for details.
-
-If you have the need for more deep customization, for instance to also allow "/sign_in" besides "/users/sign_in", all you need to do is to create your routes normally and wrap them in a +devise_scope+ block in the router:
-
-  devise_scope :user do
-    get "sign_in", :to => "devise/sessions#new"
-  end
-
-This way you tell devise to use the scope :user when "/sign_in" is accessed. Notice +devise_scope+ is also aliased as +as+ and you can also give a block to +devise_for+, resulting in the same behavior:
-
-  devise_for :users do
-    get "sign_in", :to => "devise/sessions#new"
-  end
-
-Feel free to choose the one you prefer!
-
-=== I18n
-
-Devise uses flash messages with I18n with the flash keys :success and :failure. To customize your app, you can set up your locale file:
-
-  en:
-    devise:
-      sessions:
-        signed_in: 'Signed in successfully.'
-
-You can also create distinct messages based on the resource you've configured using the singular name given in routes:
-
-  en:
-    devise:
-      sessions:
-        user:
-          signed_in: 'Welcome user, you are signed in.'
-        admin:
-          signed_in: 'Hello admin!'
-
-The Devise mailer uses a similar pattern to create subject messages:
-
-  en:
-    devise:
-      mailer:
-        confirmation_instructions:
-          subject: 'Hello everybody!'
-          user_subject: 'Hello User! Please confirm your email'
-        reset_password_instructions:
-          subject: 'Reset instructions'
-
-Take a look at our locale file to check all available messages. You may also be interested in one of the many translations that are available on our wiki:
-
-http://github.com/plataformatec/devise/wiki/I18n
-
-=== Test helpers
-
-Devise includes some tests helpers for functional specs. To use them, you just need to include Devise::TestHelpers in your test class and use the sign_in and sign_out method. Such methods have the same signature as in controllers:
-
-  sign_in :user, @user   # sign_in(scope, resource)
-  sign_in @user          # sign_in(resource)
-
-  sign_out :user         # sign_out(scope)
-  sign_out @user         # sign_out(resource)
-
-You can include the Devise Test Helpers in all of your tests by adding the following to the bottom of your test/test_helper.rb file:
-
-  class ActionController::TestCase
-    include Devise::TestHelpers
-  end
-
-If you're using RSpec and want the helpers automatically included within all +describe+ blocks, add a file called spec/support/devise.rb with the following contents:
-
-  RSpec.configure do |config|
-    config.include Devise::TestHelpers, :type => :controller
-  end
-
-Do not use such helpers for integration tests such as Cucumber or Webrat. Instead, fill in the form or explicitly set the user in session. For more tips, check the wiki (http://wiki.github.com/plataformatec/devise).
-
-=== OAuth2
-
-Devise comes with OAuth support out of the box if you're using Devise from the git repository (for now). You can read more about OAuth2 support in the wiki:
-
-* http://github.com/plataformatec/devise/wiki/OAuth2:-Overview
-* http://github.com/plataformatec/devise/wiki/OAuth2:-Testing
-
-=== Other ORMs
-
-Devise supports ActiveRecord (default) and Mongoid. To choose other ORM, you just need to require it in the initializer file.
-
-=== Migrating from other solutions
-
-Devise implements encryption strategies for Clearance, Authlogic and Restful-Authentication. To make use of these strategies, you need set the desired encryptor in the encryptor initializer config option and add :encryptable to your model. You might also need to rename your encrypted password and salt columns to match Devise's fields (encrypted_password and password_salt).
-
-== Additional information
-
-=== Warden
-
-Devise is based on Warden, which is a general Rack authentication framework created by Daniel Neighman. We encourage you to read more about Warden here:

+    # ==== Routes integration
+    #
+    # +devise_for+ is meant to play nicely with other routes methods. For example,
+    # by calling +devise_for+ inside a namespace, it automatically nests your devise
+    # controllers:
+    #
+    #     namespace :publisher do
+    #       devise_for :account
+    #     end
+    #
+    # The snippet above will use publisher/sessions controller instead of devise/sessions
+    # controller. You can revert this change or configure it directly by passing the :module
+    # option described below to +devise_for+.
+    #
+    # Also note that when you use a namespace it will affect all the helpers and methods
+    # for controllers and views. For example, using the above setup you'll end with
+    # following methods: current_publisher_account, authenticate_publisher_account!,
+    # publisher_account_signed_in, etc.
+    #
+    # The only aspect not affect by the router configuration is the model name. The
+    # model name can be explicitly set via the :class_name option.
     #
     # ==== Options
     #
     # You can configure your routes with some options:
     #
-    #  * :class_name => setup a different class to be looked up by devise,
-    #                   if it cannot be correctly find by the route name.
+    #  * class_name: setup a different class to be looked up by devise, if it cannot be
+    #    properly found by the route name.
     #
-    #      devise_for :users, :class_name => 'Account'
+    #      devise_for :users, class_name: 'Account'
     #
-    #  * :path => allows you to setup path name that will be used, as rails routes does.
-    #             The following route configuration would setup your route as /accounts instead of /users:
+    #  * path: allows you to setup path name that will be used, as rails routes does.
+    #    The following route configuration would setup your route as /accounts instead of /users:
     #
-    #      devise_for :users, :path => 'accounts'
+    #      devise_for :users, path: 'accounts'
     #
-    #  * :singular => setup the singular name for the given resource. This is used as the instance variable name in
-    #                 controller, as the name in routes and the scope given to warden.
+    #  * singular: setup the singular name for the given resource. This is used as the instance variable
+    #    name in controller, as the name in routes and the scope given to warden.
     #
-    #      devise_for :users, :singular => :user
+    #      devise_for :users, singular: :user
     #
-    #  * :path_names => configure different path names to overwrite defaults :sign_in, :sign_out, :sign_up,
-    #                   :password, :confirmation, :unlock.
+    #  * path_names: configure different path names to overwrite defaults :sign_in, :sign_out, :sign_up,
+    #    :password, :confirmation, :unlock.
     #
-    #      devise_for :users, :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification' }
+    #      devise_for :users, path_names: {
+    #        sign_in: 'login', sign_out: 'logout',
+    #        password: 'secret', confirmation: 'verification',
+    #        registration: 'register', edit: 'edit/profile'
+    #      }
     #
-    #  * :controllers => the controller which should be used. All routes by default points to Devise controllers.
+    #  * controllers: the controller which should be used. All routes by default points to Devise controllers.
     #    However, if you want them to point to custom controller, you should do:
     #
-    #      devise_for :users, :controllers => { :sessions => "users/sessions" }
+    #      devise_for :users, controllers: { sessions: "users/sessions" }
     #
-    #  * :sign_out_via => the HTTP method(s) accepted for the :sign_out action (default: :get),
+    #  * failure_app: a rack app which is invoked whenever there is a failure. Strings representing a given
+    #    are also allowed as parameter.
+    #
+    #  * sign_out_via: the HTTP method(s) accepted for the :sign_out action (default: :get),
     #    if you wish to restrict this to accept only :post or :delete requests you should do:
     #
-    #      devise_for :users, :sign_out_via => [ :post, :delete ]
+    #      devise_for :users, sign_out_via: [:post, :delete]
     #
     #    You need to make sure that your sign_out controls trigger a request with a matching HTTP method.
     #
-    #  * :module => the namespace to find controlers. By default, devise will access devise/sessions,
-    #    devise/registrations and so on. If you want to namespace all at once, use module:
+    #  * module: the namespace to find controllers (default: "devise", thus
+    #    accessing devise/sessions, devise/registrations, and so on). If you want
+    #    to namespace all at once, use module:
     #
-    #      devise_for :users, :module => "users"
+    #      devise_for :users, module: "users"
     #
-    #    Notice that whenever you use namespace in the router DSL, it automatically sets the module.
-    #    So the following setup:
+    #  * skip: tell which controller you want to skip routes from being created.
+    #    It accepts :all as an option, meaning it will not generate any route at all:
     #
-    #      namespace :publisher
-    #        devise_for :account
-    #      end
+    #      devise_for :users, skip: :sessions
     #
-    #    Will use publisher/sessions controller instead of devise/sessions controller. You can revert
-    #    this by providing the :module option to devise_for.
+    #  * only: the opposite of :skip, tell which controllers only to generate routes to:
     #
-    #    Also pay attention that when you use a namespace it will affect all the helpers and methods for controllers
-    #    and views. For example, using the above setup you'll end with following methods:
-    #    current_publisher_account, authenticate_publisher_account!, pusblisher_account_signed_in, etc.
+    #      devise_for :users, only: :sessions
     #
-    #  * :skip => tell which controller you want to skip routes from being created:
+    #  * skip_helpers: skip generating Devise url helpers like new_session_path(@user).
+    #    This is useful to avoid conflicts with previous routes and is false by default.
+    #    It accepts true as option, meaning it will skip all the helpers for the controllers
+    #    given in :skip but it also accepts specific helpers to be skipped:
     #
-    #      devise_for :users, :skip => :sessions
+    #      devise_for :users, skip: [:registrations, :confirmations], skip_helpers: true
+    #      devise_for :users, skip_helpers: [:registrations, :confirmations]
+    #
+    #  * format: include "(.:format)" in the generated routes? true by default, set to false to disable:
+    #
+    #      devise_for :users, format: false
+    #
+    #  * constraints: works the same as Rails' constraints
+    #
+    #  * defaults: works the same as Rails' defaults
+    #
+    #  * router_name: allows application level router name to be overwritten for the current scope
