Devise + LocomotiveCMS - Remember the page I was trying to visit before being asked to log in

Question

I'm trying to add a simple feature to locomotivecms (github). A very simple feature: currently users are redirected to the "main admin hub" (/admin/) after logging in - even if they were trying to edit a different page. I want them to be directed to that page after logging in instead.

It seems a very simple and reasonable thing to add, but after two days trying I've decided to ask for help.

This is what I've found out so far.

• This app doesn't use ActiveRecord, but Mongoid (the backend db is MongoDB)
• Locomotive doesn't use a simple "User" schema. Authentication is divided into two parts: "accounts" (email, password, name, etc) and "site" (it's a multi-site cms). A "site" has many "memberhips". A membership has one site_id and account_id (and also, a role, but that's not important for this, I think).
• Most of the "action" in locomotive is behind the /admin/ route. For example, the login path is /admin/log_in . Most controllers are inside an /admin/ subfolder, too.
• I've found this bit in the /admin/sessions_controller that apparently "fixes" the url to be visited after being logged in to the /admin/ root.

Here's the relevant bit:

def after_sign_in_path_for(resource)
  admin_pages_url
end

I'm nearly sure that what I need is this instead:

def after_sign_in_path_for(resource)
  stored_location_for(resource) || admin_pages_url
end

If I have understood Devise's documentation correctly, stored_location_for searches for a value in the session (session['admin_return_to'] in Locomotive's case) to "see if someone wants to go back somewhere". If it's empty, the || ensures a safe path to the admin root.

Unfortunately this doesn't work. It seems that the session variable that I need is never set up. I was assuming that Devise did this kindof automatically.

Must I set the session value myself? If so, where? Or are my assumptions wrong?

Thanks a lot!
