我正在尝试使用 Django 2.0.4 版中的自定义 MyUser 模型对用户进行身份验证。但是，当代码到达check_password我的自定义后端模块中的行时，我收到此错误：

29 if MyUser.check_password(password):
Exception Type: TypeError at /accounts/login/
Exception Value: check_password() missing 1 required positional argument: 'raw_password'
这是我的自定义后端backends.py：
class EmailAuthenticationBackend(ModelBackend):
def authenticate(self, request, email=None, password=None):
MyUser = get_user_model()
try:
# Check the email/password and return a user
user = MyUser.objects.get(email=email)
# BUG
if MyUser.check_password(password):
return user
except MyUser.DoesNotExist:
return None
密码是这样进来的。登录用户视图：
def login_user(request):
template_name = 'registration/login.html'
if request.method == 'POST':
email = request.POST['email']
password = request.POST['password']
user = authenticate(request=request, email=email, password=password)
虽然错误似乎有点不言自明，但我尝试过的所有组合都失败了。我已经阅读了文档并搜索了其他类似的方法：没有。
