我之前使用Django 1.7创建了一个可以运行的项目,现在我将它迁移到Django 1.8上。
我可以使用SQLite进行syncdb
并运行应用程序,但是当我切换到PostgreSQL时,syncdb失败了:
Creating tables...
Creating table x
Creating table y
Running deferred SQL...
Traceback (most recent call last):

django.db.utils.ProgrammingError: relation "auth_user" does not exist
我尝试删除数据库并重新创建它。 此外,我还尝试了:
python manage.py migrate auth
也会失败的:
django.db.utils.ProgrammingError: relation "django_site" does not exist
LINE 1: SELECT (1) AS "a" FROM "django_site" LIMIT 1
请帮忙解决这个问题。
python manage.py migrate --fake-initial myapp
时,它会给出错误提示:该应用程序没有迁移(您无法选择性地同步未迁移的应用程序)。 - max
