Log in user using either email address or username in Django

Question

I am trying to create an auth backend to allow my users to log in using either their email address or their username in Django 1.6 with a custom user model. The backend work

Answer 1

I wrote the code for this in 2 simple steps :

1. VIEWS.py

     if request.method == 'POST':
            userinput = request.POST['username']

            try:
                username = userbase.objects.get(email=userinput).username
            except userbase.DoesNotExist:
                username = request.POST['username']
            password = request.POST['password']

2. INDEX.html

   I created 2 input fields from which 1st is for username/email. I take whatever input is given and try to search the same data in email column of db, if it matches, I return the username and then try to authenticate , if it doesn't , I use input directly as Username.

I'm using Django 2.2
