Ruby On Rails authentication with Devise and (warden) callbacks

I have a rails app that is using Devise, with a User model, no scope. I've also added activeadmin gem in to the app, Active Admin is a gem used for adding an admin dashboard in your application. It uses Devise for logging in users and creates a separate admin_user model for the admins.

I am allowing anonymous, non-logged in users to create shopping carts, creating a session[:cart_id]. If a user logs in I want associate the user with the cart, something like 

Cart.find(session[:cart_id]).user = current_user

I was planning to use Wardens callbacks wardens callbacks to impliment this, something like so :

Warden::Manager.after_set_user :scope => :user do |user, auth, opts|

    Cart.find(session[:cart_id]).user = user 

end

However I get an error if I do that:

<% unless user_signed_in? %> throws an error :admin_user user is not logged in

Anyone got any ideas what is going on?

I've looked at related questions, but no help:

Where should warden callbacks be placed in a rails app?

Actually it turned out the issue was solved by setting the default scope in warden,in the devise initializer file.

  # Configure the default scope given to Warden. By default it's the first
  # devise role declared in your routes (usually :user).
  # config.default_scope = :user

Since the active admin routes were added above the devise routes for my user, the adminuser became the default user.

The AdminUser model that Active Admin uses also executes this callback. So, maybe, an if can solve your problem:

 Warden::Manager.after_set_user :scope => :user do |user, auth, opts|
   Cart.find(session[:cart_id]).user = user if user.class == User
 end
