我正在创建一个使用Django-rest-auth请求用户名和电子邮件的登录名，该电子邮件是密钥，因为它将用于登录用户。但是用户名在我的应用程序中也很重要，因为当搜索用户时，我想做类似“ accounts //”的事情。
在尝试执行此操作时，我按照以前的帖子中的建议添加了一个后端。
请问我该怎么办，所以注册时可以输入我的用户名和电子邮件，但是登录时我仅使用电子邮件？
backend.py
class EmailAndUsernameBackend(ModelBackend):
"""
this model backend would help me use both username and email,
remember to overide your AUTHENTICATION_BACKENDS to this one
"""
def authenticate(self, request, username=None, password=None, **kwargs):
UserModel = get_user_model()
if username is None:
username = kwargs.get(UserModel.USERNAME_FIELD)
try:
user = UserModel.objects.get(Q(email=username) | Q(username=username))
except UserModel.DoesNotExist:
UserModel().set_password(password)
else:
if user.check_password(password) and self.user_can_authenticate(user):
return user
在我的settings.py中，除了已安装的应用程序和身份验证后端外，我还有：

# 'django.contrib.auth.backends.ModelBackend',

当我尝试以上方法时，我得到：
