Django REST EmailAddress 匹配查询不存在

Question

我正在使用 Django rest-auth和 allauth来验证用户。成功注册和电子邮件验证后，我实现了一个登录 View ，其子类 rest-auth.views.LoginView像下面这样:

class ThLoginView(LoginView):

    def get(self, request):
        form = CustomUserLoginForm()
        return render(request, "users/login.html", context={"form": form})

用我自己的形式:

class CustomUserLoginForm(AuthenticationForm):
  
    class Meta:
        model = CustomUser
        fields = ('email',)

问题是当我登录时出现此错误:

DoesNotExist at /users/login/
EmailAddress matching query does not exist.

我更改的另一件重要事情是我使用电子邮件作为注册/登录而不是用户名:
设置.py

ACCOUNT_AUTHENTICATION_METHOD = 'email'
ACCOUNT_EMAIL_REQUIRED = True
ACCOUNT_USERNAME_REQUIRED = False
ACCOUNT_EMAIL_VERIFICATION = "mandatory"
ACCOUNT_UNIQUE_EMAIL = True

和我的 user模型覆盖 AbstractBaseUser像这样:

class CustomUser(AbstractBaseUser, PermissionsMixin):

    email = models.EmailField(max_length=254, unique=True)
    name = models.CharField(max_length=254, null=True, blank=True)
    username = models.CharField(max_length=254, blank=True)
    is_staff = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    last_login = models.DateTimeField(null=True, blank=True)
    date_joined = models.DateTimeField(auto_now_add=True)

    USERNAME_FIELD = 'email'

    EMAIL_FIELD = 'email'

    REQUIRED_FIELDS = []

    objects = UserManager()

    def __str__(self):
        return self.email

该错误似乎表明搜索算法没有在正确的位置查找电子邮件。用户的电子邮件肯定是输入的，因为我可以在管理页面中进行监督。为什么会发生这个错误？
注意:如果我使用 REST 可浏览 API，因此它没有链接到我的表单和模板，也会发生此错误。

Answer 1

您收到此错误是因为您用于登录的电子邮件地址在数据库表帐户电子邮件地址中不存在。 Dj-rest-auth或 Django-rest-auth包为电子邮件地址创建一个表以跟踪已验证的用户。
当您尝试使用从 manage.py 创建的用户登录时可能会遇到此错误。命令，例如 manage.py createsuperuser .基本上，从 django 管理控制台或管理命令创建的用户不会在电子邮件地址表中创建条目。
要修复此错误，您可能必须在 Accounts> Email Addresses 下创建一个新条目。从管理控制台或从 Authentication and authorization> Users 中删除用户在管理控制台中并使用 django-rest-auth API 端点再次注册(这将自动在电子邮件地址表中添加此条目)。
