Devise redirect after login fail

Question

All the questions I've found are related for a successful login with the helper after_sign_in_path_for(resource)

I have a login form in the index of the site, and when the login fails it redirects to "users/sign_in"

But how can I redirect to my "site#index" when the login fails?

Answer 1

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 you Devise initializer, include:

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

3. Make sure Rails is loadin 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. Good luck.
