我是 django 的新手,在从 AbstractBaseUser 模型创建用户时遇到了一些困难。现在我开始怀疑我的用户模型是否没有以正确的方式构建。这是我的用户模型
from django.db import models
from django.contrib.auth.models import AbstractBaseUser
class User(AbstractBaseUser):
'''
Custom user class.
'''
username = models.CharField('username', max_length=10, unique=True, db_index=True)
email = models.EmailField('email address', unique=True)
joined = models.DateTimeField(auto_now_add=True)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
并且用户仅在此其他模型中被引用
from django.db import models
from user_profile import User
class Tweet(models.Model):
'''
Tweet model
'''
user = models.ForeignKey(User)
text = models.CharField(max_length=160)
created_date = models.DateTimeField(auto_now_add=True)
country = models.CharField(max_length=30)
is_active = models.BooleanField(default=True)
然后当我尝试将我的新模型迁移到 db 时
Traceback (most recent call last):

from user_profile import User
ImportError: cannot import name 'User'
我在 ubuntu 16.04 上使用 django 1.10.1,使用 python3.5 和 mysql 作为数据库。
最佳答案
您没有从正确的包中导入。
用:
from user_profile.models import User
关于python - Django:导入错误:无法导入名称 'User',我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/39559635/
