module Callbacks
Ruby on Rails 7.1.6
Since v3.0.20Active Model Validation Callbacks
Provides an interface for any class to have ClassMethods#before_validation and ClassMethods#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.
