Django Email As User Name

Question

Is there any way I can use email as user name with out specifying custom user model. I am new to django, From past few hour I am searching and trying to find a way. I try creating custom modal but then everything get changed like admin login.

Secondly is there any way to define a custom model for specific app. eg. fronted only. So that back-end stay as is.

I just need to use email as username for users login.

Is it possible to use

USERNAME_FIELD = 'email'

Answer 2

Get the email and password using form

email = form.cleaned_data['email']
password = form.cleaned_data['password']

If the given email matches with exiting record.

try:
    user = User.objects.get(email=email)
    if user.check_password(password):
        username = user.username
        user = authenticate(username=username, password=password)
        login(request, user)
        messages.success(request, "Welcome {}".format(email))
    else:
        messages.error(request, "Password not match for  {}".format(email))
except User.DoesNotExist:
    pass
