There are few questions based on this idea like:
Implementing Ajax requests / response with django-allauth
Log in / Sign up directly on home page
https://www.reddit.com/r/django/comments/30lz11/django_allauth_implement_loginsignup_on_homepage/
but I need a little more help. I understand that I have to make form action url of modal as {% url 'account_login' %}. I have included {% load account %} and changed the 'name' and 'id' of username and password fields. My question is what other things I need to do to achieve this as it is still not working.
I had the same question and I wrote little tutorial for 3 methods I found so far. You can find details at https://stackoverflow.com/a/39235634/4992248
P.S. If it was just one method, I would post it here, but because I do not know which one you would prefer, I simply give you a link.
