Is there a way to return the number of devise users currently logged in?

Question

Is there a way to figure out how many users are actively logged into a rails app using devise?

Rails 3.1

gem \'devise\', \'~> 1.4\' gem \'dm

Answer 1

I wrote a blog post about this. We had to do this at work, and this solution seems to fit our needs.

You should add last_request_at and logged_in to your user model. last_request_at can be grabbed from the user_session information on the request. Logged_in should be set on sign_in / sign_out.
