Question

我试图扩展Django的BaseUserManager，所以当你创建一个超级用户时，我要检查organization是否存在（如果没有创建）然后使用ForeignKey为用户分配。

我得到的错误是：

我想这与模特有关吗？

帐户

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager
from project.organizations.models import Organization

class UserManager(BaseUserManager):

    def create_user(self, email, password=None):
        ...

    def create_superuser(self, email, password):

        print "Creating Demo Data..."

        if Organization.objects.filter(name="Demo Inc.").count() < 1:
            organization = Organization.objects.create(name="Demo Inc.")
            organization.save()
            print "Demo data created successfully!"
        else:
            organization = Organization.objects.all().first()

        user = self.create_user(email, password=password)
        user.organization = organization
        user.is_active = True
        user.is_admin = True
        user.save(using=self._db)
        return user

用户模型

class User(AbstractBaseUser):

    id = models.AutoField(primary_key=True)  # custom User models must have an integer PK
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now=True)

    email = models.EmailField(max_length=255, unique=True, db_index=True)
    full_name = models.CharField(max_length=255)
    organization = models.ForeignKey(Organization, related_name="users")

组织

class Organization(models.Model):

    id = UUIDField(primary_key=True, auto=True, db_index=True)
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now=True)

    name = models.CharField(max_length=200, unique=True)
    website = models.URLField(max_length=200, blank=True)

Answer 1

此处发生错误：

user = self.create_user(email, password=password)

此方法会将organization设置为None的新创建用户保存。将组织的检查和分配从create_superuser()移至create_user()。

Django，扩展BaseUserManager，
