rails--rails/activemodel/CHANGELOG.md
Steve Purcell b3ccd7b27a Don't enable validations when passing false hash values to ActiveModel.validates
Passing a falsey option value for a validator currently causes that validator to
be enabled, just like "true":

    ActiveModel.validates :foo, :presence => false

This is rather counterintuitive, and makes it inconvenient to wrap `validates` in
methods which may conditionally enable different validators.

As an example, one is currently forced to write:

      def has_slug(source_field, options={:unique => true})
        slugger = Proc.new { |r| r[:slug] = self.class.sluggify(r[source_field]) if r[:slug].blank? }
        before_validation slugger
        validations = { :presence => true, :slug => true }
        if options[:unique]
          validations[:uniqueness] = true
        end
        validates :slug, validations
      end

because the following reasonable-looking alternative fails to work as expected:

      def has_slug(source_field, options={:unique => true})
        slugger = Proc.new { |r| r[:slug] = self.class.sluggify(r[source_field]) if r[:slug].blank? }
        before_validation slugger
        validates :slug, :presence => true, :slug => true, :uniqueness => options[:unique]
      end

(This commit includes a test, and all activemodel and activerecord tests pass as before.)

Rails 4.0.0 (unreleased)

  • Passing false hash values to validates will no longer enable the corresponding validators Steve Purcell

  • 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

  • No changes.

Rails 3.2.0 (January 20, 2012)

  • Deprecated define_attr_method in ActiveModel::AttributeMethods, because this only existed to support methods like set_table_name in Active Record, which are themselves being deprecated.

    Jon Leighton

  • Add ActiveModel::Errors#added? to check if a specific error has been added Martin Svalin

  • Add ability to define strict validation(with :strict => true option) that always raises exception when fails Bogdan Gusiev

  • Deprecate "Model.model_name.partial_path" in favor of "model.to_partial_path" Grant Hutchins, Peter Jaros

Rails 3.1.3 (November 20, 2011)

  • No changes

Rails 3.1.2 (November 18, 2011)

  • No changes

Rails 3.1.1 (October 7, 2011)

  • Remove hard dependency on bcrypt-ruby to avoid make ActiveModel dependent on a binary library. You must add the gem explicitly to your Gemfile if you want use ActiveModel::SecurePassword:

    gem 'bcrypt-ruby', '~> 3.0.0'

    See GH #2687. Guillermo Iguaran

Rails 3.1.0 (August 30, 2011)

  • Alternate I18n namespace lookup is no longer supported. Instead of "activerecord.models.admins.post", do "activerecord.models.admins/post" instead José Valim

  • attr_accessible and friends now accepts :as as option to specify a role Josh Kalderimis

  • Add support for proc or lambda as an option for InclusionValidator, ExclusionValidator, and FormatValidator Prem Sichanugrist

    You can now supply Proc, lambda, or anything that respond to #call in those validations, and it will be called with current record as an argument. That given proc or lambda must returns an object which respond to #include? for InclusionValidator and ExclusionValidator, and returns a regular expression object for FormatValidator.

  • Added ActiveModel::SecurePassword to encapsulate dead-simple password usage with BCrypt encryption and salting DHH

    Model.validators
    Model.validators_on(:field)
    
  • #to_key was added to ActiveModel::Lint so we can generate DOM IDs for AMo objects with composite keys MG

  • ActiveModel::Observer#add_observer!

    It has a custom hook to define after_find that should really be in a ActiveRecord::Observer subclass:

    def add_observer!(klass)

  • Introduce validates_with to encapsulate attribute validations in a class. #2630 Jeff Dean

  • Extracted from Active Record and Active Resource.
