Django 1.6 AbstractUser m2m模型验证错误

标签: python django validation django-models

我没有使用Django 1.5.4(稳定版)的错误,但是当我在官方tar.gz上测试Django 1.6 beta 4上的应用程序时,我在启动时遇到了验证模型的错误。


models.py

from django.contrib.auth.models import AbstractUser, User

class ShopUser(AbstractUser):
    model_car = models.CharField(max_length=200)
    date_car = models.DateField()
    description = models.TextField(blank=True, db_index=True)

    manager = models.ForeignKey(User)

这是 manage.py runserver 控制台日志:

Validating models...

解决这个问题需要做些什么?

您必须在 settings.py 上声明 AUTH_USER_MODEL 。在你的情况下:

AUTH_USER_MODEL = 'your_app.ShopUser'

答案 1 :(得分:1)

对我来说,通过改变这个来修复Django 1.6.5:

from django.contrib.auth.models import AbstractUser

class CustomUser(AbstractUser):
    pass

到此:

from django.contrib.auth.models import AbstractBaseUser

class CustomUser(AbstractBaseUser):
    pass

Django 1.6.5中无需其他更改。 @ Stormlifter的建议值得,但我通过python-social-auth将这个东西用于OAuth2:

$ pip freeze
Django==1.6.5
Markdown==2.4.1
MySQL-python==1.2.5
PyJWT==0.2.1
South==1.0
basicauth==0.2
boto==2.28.0
django-filter==0.7
django-guardian==1.2.0
django-storages==1.1.8
djangorestframework==2.3.14
httplib2==0.9
oauth2==1.5.211
oauthlib==0.6.3
python-memcached==1.53
python-oauth2==0.7.0
python-openid==2.2.5
python-social-auth==0.2.1
requests==2.4.1
requests-oauthlib==0.4.1
shortuuid==0.4.2
six==1.7.2
wsgiref==0.1.2

我的新CustomUser将比默认用户做得更多,并且需要成为AUTH_USER_MODEL='myapp.CustomUser'settings.py的@jordiburgos建议。

我希望这有帮助!

您希望继承AbstractBaseUser而不是AbstractUser

但是,您似乎只想为用户存储一些其他信息,我不建议使用自定义用户模型。只需使用关系。

class ShopUser(models.Model):
    model_car = models.CharField(max_length=200)
    date_car = models.DateField()
    description = models.TextField(blank=True, db_index=True)
    user = models.OneToOneField(User)

如果您需要多个ShopUser与单个用户相关,那么您可以将其设为ForeignKey,但我认为OneToOne最有意义。

正如Django Documents所说:

Specifying a custom user model

AbstractBaseUser
