Active Model Validation Callbacks
Provides an interface for any class to have before_validation
and after_validation
callbacks.
First, include ActiveModel::Validations::Callbacks
from the class you are creating:
class MyModel
include ActiveModel::Validations::Callbacks
before_validation :do_stuff_before_validation
after_validation :do_stuff_after_validation
end
Like other before_*
callbacks if before_validation
throws :abort
then valid?
will not be called.
