Devise: Unexpectedly unable to log in

I am using Devise 1.3.4 for authentication for the backend in my application. I have not been able to log in for a couple of days. What's happening:

  • I go to the login page / admin / sign _in
  • Login with good credentials
  • See the log in which the login is running (last_sign_in_at, current_sign_in_at and current_sign_in_ip, sign_in_count increases)
  • Session controller setup is trying to redirect me to the after_sign_in_path_for parameter that I specified in the application controller (Admin :: DashboardsController # show)
  • Then, suddenly, the page with the inscription appears again. No redirection, nothing.

I checked before_filters and it is definitely Devise autorize_admin_user! a filter that causes problems (filters before it is called, filters after they are not called). This means that even after a successful login, it does not recognize me as registered.

I understand that it is difficult to find a solution without seeing most of my code. So my first question is:

How can I debug this error? How can I track exactly where the login does not work? Should I delve into the Guardian? Could this be a session / cookie issue? How can I debug this?

All ideas appreciated!

Well, after two days of swaying, I finally found the answer.

I would start debugging at the exact place where your controller is trying to authenticate the user. He “feels” as if this could have happened wrong.

In our development-based application, this is in the controller:

before_filter :authenticate_user!
