更新从 django 中的用户模型获取数据的模型字段

Question

我有一个使用 AbstractBaseUser 的用户模型。我有一个使用模型类的模型员工。我希望通过注册创建用户时，用户继承 Employee 模型的所有字段。我已经在 User 模型和 Employee 之间建立了 OnetoOne 关系。但是在查询员工模型时创建用户后，我找不到与创建的用户相关的任何数据。 用户管理员：

class UserManager(BaseUserManager):
    """
    Creates and saves a User with the given email and password.
    """
    def create_user(self, email, username, password=None):
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
            username=username
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_staffuser(self, email,username, password):
        user = self.create_user(
            email,
            password=password,
            username=username
        )
        user.is_staff = True
        user.save(using=self._db)
        return user

    def create_superuser(self, email, username, password):
        user = self.create_user(
            email,
            password=password,
            username=username
        )
        user.is_staff = True
        user.is_admin = True
        user.save(using=self._db)
        return user

用户：

class User(AbstractBaseUser):
    """
    Creates a customized database table for user
    """
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,
    )
    username = models.CharField(max_length=255, unique=True)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    is_admin = models.BooleanField(default=False)

    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['email',]

    objects = UserManager()

    def get_full_name(self):
        # The user is identified by their email address
        return self.email

    def get_short_name(self):
        # The user is identified by their email address
        return self.email

    def __str__(self):
        return self.email

    def has_perm(self, perm, obj=None):
        "Does the user have a specific permission?"
        # Simplest possible answer: Yes, always
        return True

    def has_module_perms(self, app_label):
        "Does the user have permissions to view the app `app_label`?"
        # Simplest possible answer: Yes, always
        return True

我使用 OneToOneField(User, on_delete=models.CASCADE, null=True) 扩展了具有 OnetoOne 关系的用户模型

Employee model:

    class Employee(models.Model):
        """
        Create employee attributes
        """
        employee_user = models.OneToOneField(User, on_delete=models.CASCADE, null=True)
        e_id = models.IntegerField(unique=True, null=False)
        first_name = models.CharField(max_length=128)
        last_name = models.CharField(max_length=128)
        address = models.CharField(max_length=256, blank=True)
    phone_number = models.CharField(max_length=128, blank=True)
    email = models.EmailField(max_length=128, unique=True)
        def get_absolute_url(self):
            return reverse("employee:employee-list")
        @receiver(post_save, sender=User)
    def create_or_update_user_profile(sender, instance, created, **kwargs):
        if created:
            Employee.objects.create(employee_user=instance)
        instance.Employee.save()

在此模型中，还有一个名为 email 的字段。我必须保留这个字段，因为我正在使用这个模型来创建一个用于创建员工的表单。但问题是，用户模型的电子邮件字段与员工电子邮件字段冲突。我必须保留两个电子邮件字段。

我可以用用户电子邮件字段更新员工电子邮件字段吗？如果是，那么查询应该是什么？？？

您已经创建了一个自定义用户模型，因此您需要从您的设置文件中导入他的 Auth_User_model，而不是使用 django 内置的身份验证用户。 你可以这样做

from django.conf import settings

employee_user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
