我使用两个应用(自定义用户和客户端)启动新项目。在 customuser 中,我重新定义默认用户模型,在客户端中,将UserTrofile与OneToOne字段一起设置为User。然后我跑
from selenium import webdriver
driver = webdriver.Chrome(executable_path='/path/to/chromedriver')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()
在这一点上都好 发髻然后我跑
makemigartions customuser
makemigrations client
migrate
出现错误
createsuperuser
customuser / models.py
return Database.Cursor.execute(self, query, params)
django.db.utils.IntegrityError: NOT NULL constraint failed: client_profile.position_id
的客户机/ models.py
from django.contrib.auth.models import AbstractUser, BaseUserManager
from django.db import models
from django.utils.translation import ugettext_lazy as _
class UserManager(BaseUserManager):
"""Define a model manager for User model with no username field."""
use_in_migrations = True

if not email:

email = self.normalize_email(email)
user = self.model(email=email, **extra_fields)
user.set_password(password)
user.save(using=self._db)
return user

if extra_fields.get('is_superuser') is not True:
raise ValueError('Superuser must have is_superuser=True.')
return self._create_user(email, password, **extra_fields)
class User(AbstractUser):
"""User model."""
username = None
email = models.EmailField(_('email address'), unique=True)
phone = models.CharField(max_length=20, blank=True)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
objects = UserManager()
帮助理解为什么会发生这种情况并解决此问题。
答案 0 :(得分:2)
您收到错误是因为您创建的用户没有设置position
。如果在数据库中允许null,则需要设置null=True
。
class Profile(models.Model):
...
position = models.ForeignKey('Position',blank=True, null=True)
完成此操作后,您需要创建迁移并迁移以删除数据库中的NOT NULL约束。
