Hi blackcaps,
This error is due to "before_filter :login_required" . you have added an before filter in you controller and the method "login_required" in not defined in that controller. so it may check for the method in application controller. i think you have not mentioned the "login_required" method in the application controller. so do cross check and make sure to have "login_required" method in application controller .
Thank You,
Uma. |
