Merging ActiveAdmin users with existing user model

Question

I\'ve set up ActiveAdmin early in my project and used the default admin_users model for authentication. I\'ve since used Devise to set up a separate User model and

Answer 1

For a quick code block of how to do this using an existing "User" model with activeadmin, the answer is actually really easy. In the ApplicationController:

class ApplicationController < ActionController::Base
    def authenticate_admin_user! #use predefined method name
      redirect_to '/' and return if user_signed_in? && !current_user.is_admin? 
      authenticate_user! 
    end 
    def current_admin_user #use predefined method name
      return nil if user_signed_in? && !current_user.is_admin? 
      current_user 
    end 
end

And just use what Devise already has set up for authentication. The redirect_to is where you want to send users who ARE signed in and DO NOT have administrative privileges.
