Need to know after_create callbacks

Is there any way to know all after_create call-back functions written in a particular model level?

For instance: I have written callback_function1 and callback_function2 in after_create for the User model. I need to know both callback functions.

Sure. This wil give you all callbacks:

MODEL.__callbacks

You can then filter the result

MODEL.__callbacks[:create].select{_1.kind == :after}.map(&:filter)

If the callback is a symbol for a method, it will give you that symbol. It it’s a block, it will give you the file and line of the block.

@brenogazzola Fantastic. Thank you :pray:

In case the naming of that variable is unclear, that looks like undocumented internals. Just be a little careful using that in production. Those kinds of things can change without notice.
