Use helper methods within a controller

Question

I defined a helper abc() in annotations_helper.rb. What do I have to do such that I can use this method in annotations_controller.rb?

Answer 1

In general helpers are supposed to be "view helpers" and not called from controllers.

You probably want to put something like that in application_controller.rb

Answer 2

This is usually not a good practice to use a helper in your controllers. You should try to move the logic inside a model or if the logic is too generic, you should move that to lib/some_lib.rb and include that in your model to use.
