*Rails 3.0.0 [beta 2] (April 1st, 2010)*
|
|
|
|
* #new_record? and #destroyed? were removed from ActiveModel::Lint. Use
|
|
persisted? instead. A model is persisted if it's not a new_record? and it was
|
|
not destroyed? [MG]
|
|
|
|
* Added validations reflection in ActiveModel::Validations [JV]
|
|
|
|
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]
|
|
|
|
|
|
*Rails 3.0.0 [beta 1] (February 4, 2010)*
|
|
|
|
* 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)
|
|
klass.add_observer(self)
|
|
klass.class_eval 'def after_find() end' unless
|
|
klass.respond_to?(:after_find)
|
|
end
|
|
|
|
* Change the ActiveModel::Base.include_root_in_json default to true for Rails 3 [DHH]
|
|
|
|
* Add validates_format_of :without => /regexp/ option. #430 [Elliot Winkler, Peer Allan]
|
|
|
|
Example :
|
|
|
|
validates_format_of :subdomain, :without => /www|admin|mail/
|
|
|
|
* Introduce validates_with to encapsulate attribute validations in a class. #2630 [Jeff Dean]
|
|
|
|
* Extracted from Active Record and Active Resource.
