@@callbacks =

this bit of code creates a “run_blank” function for everything value in the @@callbacks array. this function can then be inserted in the appropriate place in the save, new, destroy, etc overrides basically, this is how we recreate the callback functions

["before_validation", "before_validation_on_create", "before_validation_on_update",
