Rails 4: before_filter vs. before_action

Question

In rails >4.0.0 generators creates CRUD operations with before_action not before_filter. It seems to do the same thing. So what\'s the difference b

Answer 1

To figure out what is the difference between before_action and before_filter, we should understand the difference between action and filter.

An action is a method of a controller to which you can route to. For example, your user creation page might be routed to UsersController#new - new is the action in this route.

Filters run in respect to controller actions - before, after or around them. These methods can halt the action processing by redirecting or set up common data to every action in the controller.

Rails 4 –> _action

Rails 3 –> _filter
