## Rails 4.0.0 (unreleased) ##
* Add `ActiveModel::Errors#full_messages_for`, to return all the error messages
for a given attribute.
Example:
class Person
include ActiveModel::Validations
attr_reader :name, :email
validates_presence_of :name, :email
end
person = Person.new
person.valid? # => false
person.errors.full_messages_for(:name) # => ["Name can't be blank"]
*Volodymyr Shatsky*
* Added a method so that validations can be easily cleared on a model.
For example:
class Person
include ActiveModel::Validations
validates_uniqueness_of :first_name
validate :cannot_be_robot
def cannot_be_robot
errors.add(:base, 'A person cannot be a robot') if person_is_robot
end
end
Now, if someone runs `Person.clear_validators!`, then the following occurs:
Person.validators # => []
Person._validate_callbacks.empty? # => true
*John Wang*
* `has_secure_password` does not fail the confirmation validation
when assigning empty String to `password` and `password_confirmation`.
Fixes #9535.
Example:
# Given User has_secure_password.
@user.password = ""
@user.password_confirmation = ""
@user.valid?(:update) # used to be false
*Yves Senn*
* `validates_confirmation_of` does not override writer methods for
the confirmation attribute if no reader is defined.
Example:
class Blog
def title=(new_title)
@title = new_title.downcase
end
# previously this would override the setter above.
validates_confirmation_of :title
end

## Rails 4.0.0.beta1 (February 25, 2013) ##
* Add `ActiveModel::Validations::AbsenceValidator`, a validator to check the
absence of attributes.
class Person
include ActiveModel::Validations
attr_accessor :first_name
validates_absence_of :first_name
end
person = Person.new
person.first_name = "John"
person.valid?
# => false
person.errors.messages
# => {:first_name=>["must be blank"]}
*Roberto Vasquez Angel*
* `[attribute]_changed?` now returns `false` after a call to `reset_[attribute]!`.
*Renato Mascarenhas*
* Observers was extracted from Active Model as `rails-observers` gem.
*Rafael Mendonça França*
* Specify type of singular association during serialization.
*Steve Klabnik*
* Fixed length validator to correctly handle `nil`. Fixes #7180.
*Michal Zima*
* Removed dispensable `require` statements. Make sure to require `active_model` before requiring
individual parts of the framework.
*Yves Senn*

* Use BCrypt's `MIN_COST` in the test environment for speedier tests when using `has_secure_password`.
*Brian Cardarella + Jeremy Kemper + Trevor Turk*
* Add `ActiveModel::ForbiddenAttributesProtection`, a simple module to
protect attributes from mass assignment when non-permitted attributes are passed.
*DHH + Guillermo Iguaran*
* `ActiveModel::MassAssignmentSecurity` has been extracted from Active Model and the
`protected_attributes` gem should be added to Gemfile in order to use
`attr_accessible` and `attr_protected` macros in your models.
*Guillermo Iguaran*
* Due to a change in builder, `nil` and empty strings now generate
closed tags, so instead of this:
<pseudonyms nil=\"true\"></pseudonyms>
it generates this:
<pseudonyms nil=\"true\"/>
*Carlos Antonio da Silva*
* Inclusion/exclusion validators accept a method name passed as a symbol to the
`:in` option.
This allows to use dynamic inclusion/exclusion values using methods, besides
the current lambda/proc support.
*Gabriel Sobrinho*
* `ActiveModel::Validation#validates` ability to pass custom exception to the
`:strict` option.
*Bogdan Gusiev*
* Changed `ActiveModel::Serializers::Xml::Serializer#add_associations` to by default
propagate `:skip_types, :dasherize, :camelize` keys to included associations.
2013-03-15 02:25:03 -04:00
It can be overridden on each association by explicitly specifying the option on one
or more associations
*Anthony Alberto*
* Changed `ActiveModel::Serializers::JSON.include_root_in_json` default value to false.
change AMS::JSON.include_root_in_json default value to false Changes: * Update `include_root_in_json` default value to false for default value to false for `ActiveModel::Serializers::JSON`. * Remove unnecessary change to include_root_in_json option in wrap_parameters template. * Update `as_json` documentation. * Fix JSONSerialization tests. Problem: It's confusing that AM serializers behave differently from AR, even when AR objects include AM serializers module. class User < ActiveRecord::Base; end class Person include ActiveModel::Model include ActiveModel::AttributeMethods include ActiveModel::Serializers::JSON attr_accessor :name, :age def attributes instance_values end end user.as_json => {"id"=>1, "name"=>"Konata Izumi", "age"=>16, "awesome"=>true} # root is not included person.as_json => {"person"=>{"name"=>"Francesco", "age"=>22}} # root is included ActiveRecord::Base.include_root_in_json => false Person.include_root_in_json => true # different default values for include_root_in_json Proposal: Change the default value of AM serializers to false, update the misleading documentation and remove unnecessary change to false of include_root_in_json option with AR objects. class User < ActiveRecord::Base; end class Person include ActiveModel::Model include ActiveModel::AttributeMethods include ActiveModel::Serializers::JSON attr_accessor :name, :age def attributes instance_values end end user.as_json => {"id"=>1, "name"=>"Konata Izumi", "age"=>16, "awesome"=>true} # root is not included person.as_json => {"name"=>"Francesco", "age"=>22} # root is not included ActiveRecord::Base.include_root_in_json => false Person.include_root_in_json => false # same behaviour, more consistent Fixes #6578.
2012-06-06 02:11:39 -04:00
Now, AM Serializers and AR objects have the same default behaviour. Fixes #6578.
class User < ActiveRecord::Base; end
class Person
include ActiveModel::Model
include ActiveModel::AttributeMethods
include ActiveModel::Serializers::JSON
attr_accessor :name, :age
def attributes
instance_values
end
end
user.as_json
=> {"id"=>1, "name"=>"Konata Izumi", "age"=>16, "awesome"=>true}
# root is not included
person.as_json
=> {"name"=>"Francesco", "age"=>22}
# root is not included
*Francesco Rodriguez*
* Passing false hash values to `validates` will no longer enable the corresponding validators.
*Steve Purcell*
* `ConfirmationValidator` error messages will attach to `:#{attribute}_confirmation` instead of `attribute`.
*Brian Cardarella*
* Added `ActiveModel::Model`, a mixin to make Ruby objects work with AP out of box.
*Guillermo Iguaran*
* `AM::Errors#to_json`: support `:full_messages` parameter.
*Bogdan Gusiev*
2012-04-23 21:30:24 -04:00
* Trim down Active Model API by removing `valid?` and `errors.full_messages`.
*José Valim*
* When `^` or `$` are used in the regular expression provided to `validates_format_of`
and the `:multiline` option is not set to true, an exception will be raised. This is
to prevent security vulnerabilities when using `validates_format_of`. The problem is
described in detail in the Rails security guide.
*Jan Berdajs + Egor Homakov*
