问题是在创建新用户时出现的。它说相关的对象不存在。

accounts model

class Accounts(AbstractBaseUser):
    username = models.CharField(max_length=30, unique=True)
    email = models.EmailField(verbose_name="email", max_length=60, unique=True)
    date_created = models.DateTimeField(
        verbose_name='date_joined', auto_now_add=True)
    last_login = models.DateTimeField(
        verbose_name='last_login', auto_now_add=True)
    is_admin = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    # setting username as a key to login. Note: email can also be used in it
    USERNAME_FIELD = 'username'
    REQUIRED_FIELDS = ['first_name', 'last_name', 'email']

store model
class Customer(models.Model):
    username = models.OneToOneField(
        Accounts, on_delete=models.CASCADE, null=True, blank=True)
    name = models.CharField(max_length=100,  null=True)
    email = models.CharField(max_length=100, null=True)

    def __str__(self):
        return self.name

Answer 1

在您的视图中，如错误所示，您已尝试

customer = request.user.customer

虽然在您的customer类中除了用户名之外没有任何名称Customer a

因此，要么：

1. 将视图中的查询更改为：

客户= request.user.username

或

1. 将类中的用户名更改为customer：

customer = models.OneToOneField( Accounts，on_delete=models.CASCADE，null=True，blank=True)
