Devise authentication with ActionController::Metal

Question

I need to make an API with Devise authentication. API is better to implement with ActionController::Metal descendant, but Devise relies on before_filter method which is only defined in ActionController::Base descendants.

Any solutions?

Answer 1

Simply include some helpers in your ApplicationController

Example:

class ApplicationController < ActionController::Metal
    include AbstractController::Callbacks # This adds before_filter
    include Devise::Controllers::Helpers # This adds current_user
    ...
end
