Rails/Devise: execute action after automatic login

Alright, so I am rather new to the Rails environment, and I feel I am missing something.

I wish to execute a particular action after login, be it after login from a form or automatic login.

I found out that after_sign_in_path_for is executed after a "regular" login. I already use it in my Application controller.

class ApplicationController < ActionController::Base

[…]

def after_sign_in_path_for(resource)
    myAction
end

However, it seems that this method isn't called when a user is logged in through the Devise Remember option.

I found out that after_remembered is executed after a user is automatically logged in, however I don't understand how to use it. I don't want to modify the Devise gem just to add my action to the method, and the following doesn't seem to work:

class ApplicationController < ActionController::Base

[…]

def after_remembered()
    myAction
end

I am at a loss here. Either I don't understand how to use after_remembered, or I look at it the wrong way and there is another solution for that (should it cover either both cases or only the case with "remember me" automatic login, is fine for me). Does anyone have any idea to make it work?

PS: I am working on an app I haven't developed myself. If you feel you need more code in order to answer, tell me and I will edit my post.
