In Active Record, the callbacks for save are before_save/after_save, the callbacks for destroy are before_destroy/after_destroy, and so forth.
Except that the callbacks for validate are before_validation/after_validation. Why not before_validate/after_validate?
I have been using rails for over a decade and never noticed that. Now it’s going to bother me!
As you say, consistency would demand
before_[noun]
before_saving
before_destruction
before_validation
or
before_[verb]
before_save
before_destroy
before_validate
I’d love to know whether there is a rationale behind this, or whether it is just a historical artifact…
