Since ActiveModel::Errors instance keeps all error messages as hash
we should duplicate this object as well.
Previously ActiveModel::Errors was a subclass of ActiveSupport::OrderedHash,
which results in different behavior on dup, this may result in regression for
people relying on it.
Because Rails 3.2 stills supports Ruby 1.8.7 in order to properly fix this
regression we need to backport #initialize_dup.
Without that patch when using ActiveModel::AttributeMethods
in a class that does not respond to `attributes` method,
stack level too deep error will be raised on non existing
method. While documentation is clear that you need to define
`attributes` method in order to use AttributeMethods module,
`stack level too deep` is rather obscure and hard to debug,
therefore we should try to not break `method_missing` if
someone forgets about defining `attributes`.
Nested I18n namespace lookup under activerecord.models is deprecated now (c19bd4f).
But when a model uses accepts_nested_attributes_for, its Errors object can have
an attribute name with "addresses.street" style. In this case, the dots should be
substituted with slashes so that we can provide the translation under the
"activemodel.attributes.person.addresses/street" key.
This implements the ActiveModel::Serializer object. Includes code, tests, generators and guides.
From José and Yehuda with love.
Conflicts:
railties/CHANGELOG.md
The following constants were renamed:
ActiveModel::Serialization => ActiveModel::Serializable
ActiveModel::Serializers::JSON => ActiveModel::Serializable::JSON
ActiveModel::Serializers::Xml => ActiveModel::Serializable::XML
The main motivation for such a change is that `ActiveModel::Serializers::JSON`
was not actually a serializer, but a module that when included allows the target to be serializable to JSON.
With such changes, we were able to clean up the namespace to add true serializers as the ArraySerializer.
When you've got an AR Model and you override the `as_json` method,
you should be able to add default options to the renderer, like this:
class User < ActiveRecord::Base
def as_json(options = {})
super(options.merge(:except => [:password_digest]))
end
end
This was not possible before this commit. See the added test case.
Previously, it would use send() to get the attribute. In Active
Resource, this would rely on hitting method missing. If a method with
the same name was defined further up the ancestor chain, that method
would wrongly be called.
This change fixes test_to_xml_with_private_method_name_as_attribute in
activeresource/test/cases/base_test.rb, which was broken after
51bef9d8fb, because that change made
to_xml use serializable_hash.
There's no harm in generating a method name that's already defined on
the host class, since we're generating the attribute methods in a module
that gets included. In fact, this is desirable as it allows the host
class to call super.
