I want to override authenticate_user and current_user method of devise gem

Question

I want to override authenticate_user! and current_user method of devise gem in my application Controller can you please help me with regards to that Thanks

Answer 1

You may be able to monkey-patch it like:

module Devise
  module Controllers
    module Helpers
      def authenticate_user!
        #do some stuff
      end
    end
  end
end   

But I would ask what the ultimate goal is, because Devise has some customizability built into it already, and overriding these methods makes me wonder "why use Devise at all?"

Answer 2

On overriding how a user is authenticated:

Devise uses Warden under the hood https://github.com/plataformatec/devise/blob/master/lib/devise/controllers/helpers.rb

So you can just add a new strategy in Warden to authenticate your users. See https://github.com/hassox/warden/wiki/Strategies

You should not need to override current_user. What challenge are you facing ? Do you need a different model returned ?
