我是 django 新手，我想对用户进行身份验证，因此email我编写了一个自定义身份验证，如文档中所示，但它似乎没有被调用，我不知道我该怎么做？usernamepassword

设置.py

AUTHENTICATION_BACKENDS = ('accounts.backend.AuthBackend',)

视图.py

            return render(request, 'accounts/login.html')
    else:
         return render(request, 'accounts/login.html')

from django.contrib.auth.models import User
from django.db.models import Q


class AuthBackend(object):
    supports_object_permissions = True
    supports_anonymous_user = False
    supports_inactive_user = False

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None …
