【问题描述】:
将项目从 django 1.7.4 迁移到 1.8.5 时遇到一个奇怪的问题
在我的项目中,我像这样扩展基本用户模型:
应用用户:
class User(AbstractUser):
age = models.IntegerField()
def __unicode__(self):
return self.username
现在由于某些原因在 django 1.8.5 中迁移时,我必须从做开始
python manage.py makemigrations
这将为用户应用程序进行迁移。
如果我这样做了
python manage.py migrate
在此之后直接失败并出现此错误
django.db.utils.ProgrammingError: relation "users_user" does not exist
然后我做:
python manage.py migrate users
失败了
"Error creating new content types. Please make sure contenttypes "
RuntimeError: Error creating new content types. Please make sure
contenttypes is migrated before trying to migrate apps individually.
有趣的是,即使这失败了,现在正在运行
python manage.py migrate
作品

在从较旧的 django 版本迁移到 1.8 时,有没有人遇到过同样的问题?
