在引擎（特别是在Devise）中覆盖控制器

Question

I want to remove Devise's set_flash_message on signin/signout, so I created my own sessions_controller, copied verbatim from devise's. I copied the view over to app/views/sessions, and changed the route. Now, when I sign in, it redirects me back to the sign in page. The rails log shows

Processing by SessionsController#new as HTML

which doesn't show up when I use the built-in session controller. Any ideas?

I can work around this without overriding the controller, but I suspect I'll want to do that anyway at some point and hit this same problem. Jose has no idea. How can I troubleshoot this?

If you are just wanting to customize the messages that devise uses, just edit the devise.en.yml file

config/locales/devise.en.yml

en:
  ...
  devise:
    sessions:
      signed_in: 'Signed in successfully.'
      signed_out: 'Signed out successfully.'
