Django log user IP for user_login_failed signal

Unfortunately user_login_failed singal don't pass request as argument.

Checkout django-axes — https://github.com/django-pci/django-axes/

It uses a custom view decorator to track failed logins.

I just found in newer Django version (I am using 2.1) has updated this and now it includes the request object in the user_login_failed signal:
