Instance Method Details

#add_callback(resource, &block) ⇒ Object

Add an additional callback hook to not loaded resource. If given resource already loaded callback will be invoked immediately.

This method will be replaced by explicit callback handling when query methods return explicit future objects.

Examples:

user = MyUser.find 1, &callback_one
Acfs.add_callback(user, &callback_two)
