这是我一直在做的事情：麻烦的Django建立在Heroku利用南 - 不断收到ProgrammingError：关系不存在
本地 - 在那里我有一个全新的Postgres数据库，以及两种机型.py文件从两个不同的应用程序：
python manage.py syncdb
python manage.py schemamigration api --initial
python manage.py schemamigration extapi --initial
python manage.py migrate api 0001 --fake
python manage.py migrate extapi 0001 --fake
这工作膨胀，我可以添加东西到数据库就好了。
然后，推到Heroku的，在那里我已经创建了一个空的应用程序时：
git add .
git commit -m "Ready to go to Heroku"
git push heroku master
heroku run python manage.py syncdb
输出这样的：
Running `python manage.py syncdb` attached to terminal... up, run.9548

Not synced (use migrations):
- api
- extapi
然后我试着将这些应用程序迁移与heroku run python manage.py migrate并获得这个错误：
Running `python manage.py migrate` attached to terminal... up, run.3724
Running migrations for api:
- Migrating forwards to 0001_initial.

django.db.utils.ProgrammingError: relation "extapi_summary" does not exist
对我来说，它看起来像表只是不是cr吃了，但我不知道为什么不。当我运行heroku run python manage.py sqlall时，它表示一切都已经完成，但后来我查看了数据库本身（heroku在s3上制作的一个），app_one和app_two中没有任何内容。再次，这一切都在当地完美实现，只是当它在heroku上出现问题时才会崩溃。
如果运行'./manage.py migrate extapi'然后'./manage.py migrate'，会发生什么？ –
运行'heroku run ./manage.py migrate extapi'后，得到'django.db.utils.ProgrammingError：relation“api_userprofile”不存在“。目前在extapi.models的顶部有一个来自api.models import UserProfile的导入。要尝试改变进口... –
是的，同样的问题。 –
