Ruby on Rails - Devise and Active Admin single model HABTM

Im using rails 3.2 and am having trouble using pre-created devise alongside active admin using a single model and an HABTM relation to a Role model.

I've followed this tutorial http://jaysonlane.net/2012/04/rails-devise-and-active-admin-single-user-model

And have altered a few things such as

unless current_user.admin?

for

unless current_user.roles.first.id==1 #checks if its an admin or not

If I log in with a regular user and try to access admin page through :300/admin I get a "Permission denied", which is a good thing.

However, if I log with an admin account(it sucessfully logs as an admin), and go to :3000/admin, it displays and error:

NoMethodError in Admin/dashboard#index
undefined method for 'destroy_admin_user_session_path'

changing it to:

config.logout_link_path = :destroy_current_admin_user_session_path
or
config.logout_link_path = :destroy_current_user_session_path

won't help either.

Thanks you in advance for your help

FIXED:

Had to run rake routes and alter the defaut active_admin initializer path and methods to my routes.

As for the error in logging out, apparently the default method for signing out with Active admin is :get. Therefore, an error occurs when clicking "Logout" in active admin. To fix this, go to config->initializers->active_admin.rb and add

config.logout_link_method= :delete

Hope this helps someone.

Thank you again @pjammer and @iain for your help in poiting me in the right direction. Regards
