Devise redirect after login fail

1. Create a custom_failure.rb in your lib directory, with:

    class CustomFailure < Devise::FailureApp
      def redirect_url
        your_path
      end
   
      def respond
        if http_auth?
          http_auth
        else
          redirect
        end
      end
    end
   

2. In your Devise initializer, include:

      config.warden do |manager|
        manager.failure_app = CustomFailure
      end
   

3. Make sure Rails is loading your lib files, in your application.rb :

    config.autoload_paths += %W(#{config.root}/lib)
   

Don’t forget to restart your server.

I don’t think there’s an easier way to do this.
