Logout from ActiveAdmin destroy other sessions

问题

I am using devise with activeadmin and one other model. If I open both interfaces on browser and logout from one it will also destroy other sessions.

Started GET "/admin/logout" for 127.0.0.1 at 2015-11-03 19:45:25 +0500
Processing by ActiveAdmin::Devise::SessionsController#destroy as HTML

By default when Devise::SessionsController#destroy is invoked it will destroy the sessions from all scopes. This is configurable via sign_out_all_scopes. So to disable it, set it to false:

# config/initializers/devise.rb
config.sign_out_all_scopes = false
