Django REST电子邮件地址匹配查询不存在

我正在使用django

restauth

和

allauth

对用户进行身份验证。在成功注册和电子邮件验证之后，我实现了一个登录视图，它的子类为

rest auth.views.LoginView

，如下所示：

class ThLoginView(LoginView):

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

以我自己的形式：

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

问题是登录时出现以下错误：

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

我改变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 我的

user

模型覆盖了

AbstractBaseUser

，如下所示：

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

这个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监督这一点。为什么会发生这种错误

注意：如果我使用REST可浏览API，因此它未链接到我的表单和模板，也会发生此错误

完全回溯

当我处理自定义用户模型时，我也面临同样的问题。原因是我首先进行了迁移并使用django用户模型迁移到数据库。过了一会儿，我实现了我的自定义用户模型并进行了迁移。 Django详细描述了挑战：

创建数据库表后更改AUTH_USER_模型要困难得多，因为它会影响外键和多对多关系

此更改无法自动完成，需要手动修复架构，从旧用户表中移动数据，并可能手动重新应用某些迁移。请参见#25313了解步骤的概要

---

如果可以的话，我建议从一个新的数据库开始。我就是这样解决这个问题的。否则，请尝试按照教程进行操作。

由于数据库表Account email address中不存在用于登录的电子邮件地址，因此会出现此错误

Dj rest-auth

或

Django rest-auth

packages为电子邮件地址创建一个表，以跟踪已验证的用户

当您尝试使用通过

manage.py

命令（如

manage.py createsuperuser

）创建的用户登录时，可能会遇到此错误。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，您可能必须从管理控制台的

帐户>电子邮件地址下创建一个新条目，或从管理控制台的
身份验证和授权>用户中删除该用户
，然后使用django rest auth API端点重新注册（这将自动在电子邮件地址表中添加此条目）.
请显示您的完整回溯。@DanielRoseman添加了完整回溯这似乎根本没有使用您的LoginView。您确定已正确配置URL吗？
/users/login/
正在使用
ThLoginView
子类化
LoginView
：
path（'login/'，views.ThLoginView.as_view（），name='rest_logout'），
我不明白您在这里做什么。rest_auth不使用表单，它使用序列化程序，您还没有自定义它将使用的序列化程序。您的身份验证用户模型设置是什么？
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
