Rails 4.0.1 (November 01, 2013)

  • Fix has_secure_password to honor bcrypt-ruby's cost attribute.

    T.J. Schuck

  • inclusion / exclusion validations with ranges will only use the faster Range#cover for numerical ranges, and the more accurate Range#include? for non-numerical ones.

    Fixes range validations like :a..:f that used to pass with values like :be.

    Fixes #10593.

    Charles Bergeron

Rails 4.0.0 (June 25, 2013)

  • Fix regression in has_secure_password. When a password is set, but a confirmation is an empty string, it would incorrectly save.

    Steve Klabnik and Phillip Calvin

  • 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
    

    Yves Senn

  • 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. 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. 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

  • 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.
