In the first run of the sell-out Magic Models - â??I canâ??t believe its an
ActiveRecordâ? - Super Show - you were amazed as we stripped away the
necessary essentials of an ActiveRecord - right in front of your eyes -
the necessary became unnecessary.
We removed the validates_presence_of validationsâ?¦ and the Magic Model
still validated.
We removed the has_many, belongs_to, and has_many :through associationsâ?¦
and the Magic Model still associated.
We removed the actual class definition itself - the very thing that
provides the ActiveRecord CRUD layerâ?¦ and the Magic Model still CRUDded.
In the new Magic Models, Virtual Validations get Virtuous!
g = Group.new
g.name = “x” * 51
=> "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxâ?
g.valid?
=> false
g.errors.full_messages
=> [“Name is too long (maximum is 50 characters)”]
