* master: Bring returning back to ease migration. Remove duplicated logic. Eager loading an association should not change the count of children fix loading of different elements in array then int and string [#5036 state:resolved] Tidy up previous commit. test and fix collection_singular_ids= with string primary keys [#5125 state:resolved] Handle edge cases in the previous patch. Improved how AppGenerator generates the application name. It now detects the current app name whenever possible. This means that renaming the residing directory will not effect the app name generated by AppGenerator. ActiveModel::Errors json serialization to work as Rails 3b4 [#5254 state:resolved] Add missing require in ActiveSupport::HashWithIndifferentAccess [#5189 state:resolved] Add an internal (private API) after_touch callback. [#5271 state:resolved] added failing touch propagation test Makes rails destroy scaffold don't duplicate routes.draw do |map| |map| when using the deprecated syntax Failing test to check for route file corruption if legacy map parameter is used. [#5263 state:open] Corrected the rake test:units and test:functionals description [#5251 state:committed] Use AS::OrderedHash when trusting in the order of the hash Fix label form helper to use I18n and html options, without the need of 'nil' text param:
== Welcome to Rails
Rails is a web-application framework that includes everything needed to create
database-backed web applications according to the Model-View-Control pattern.
This pattern splits the view (also called the presentation) into "dumb"
templates that are primarily responsible for inserting pre-built data in between
HTML tags. The model contains the "smart" domain objects (such as Account,
Product, Person, Post) that holds all the business logic and knows how to
persist themselves to a database. The controller handles the incoming requests
(such as Save New Account, Update Product, Show Post) by manipulating the model
and directing data to the view.
In Rails, the model is handled by what's called an object-relational mapping
layer entitled Active Record. This layer allows you to present the data from
database rows as objects and embellish these data objects with business logic
methods. You can read more about Active Record in
link:files/vendor/rails/activerecord/README.html.
The controller and view are handled by the Action Pack, which handles both
layers by its two parts: Action View and Action Controller. These two layers
are bundled in a single package due to their heavy interdependence. This is
unlike the relationship between the Active Record and Action Pack that is much
more separate. Each of these packages can be used independently outside of
Rails. You can read more about Action Pack in
link:files/vendor/rails/actionpack/README.html.
== Getting Started
1. Install Rails at the command prompt if you haven't yet:
gem install rails
2. At the command prompt, create a new Rails application:
rails new myapp
where "myapp" is the application name.
3. Change directory to +myapp+ and start the web server:
cd myapp; rails server
Run with <tt>--help</tt> for options.
4. Go to http://localhost:3000/ and you'll see:
"Welcome aboard: You're riding Ruby on Rails!"
5. Follow the guidelines to start developing your application. You can find
the following resources handy:
* The README file created within your application.
* The {Getting Started Guide}[http://guides.rubyonrails.org/getting_started.html].
* The {Ruby on Rails Tutorial Book}[http://railstutorial.org/book].
