在Heroku Django部署：失败在createsuperuser：django.db.utils.OperationalError：没有这样的表：auth_user

有关于这个特定的错误有很多stackoverflow问题，但我认为没有类似的情况，我有。我一直在关注djangogirls heroku部署教程，从settings.py的数据库设置中确保我已经做得正确。在Heroku Django部署：失败在createsuperuser：django.db.utils.OperationalError：没有这样的表：auth_user

我在应用程序中启动并运行了应用程序。尝试访问管理员，它仍然有auth_user的操作错误。因此，我认为我可能在移植过程中出错了。所以以下步骤我这样做：

1）蟒蛇manage.py makemigrations

2）Python的manage.py迁移

3）git的补充。 ，git的承诺-m “ - ” 混帐推Heroku的主

4）Heroku的执行python manage.py makemigrations

5）Heroku的执行python manage.py迁移

现在最后一步，这里的一切都失败了，说还有东西要迁徙。

6）Heroku的执行python manage.py createsuperuser

我做的步骤是，他们提出和被接受的建议，但它似乎无法在我的情况下工作。有任何想法吗？

似乎是错在这里在这一点上了。 迁移说，这是申请，但showmigrations说否则

最后，我最终重新做了整个设置，并没有任何问题没有问题。无论如何，只要万一有人遇到同样的问题，这个问题最终会得到更好的回答。

看来你的Heroku错误陈述那里......

You have 16 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, blog, contenttypes, sessions. Run 'python manage.py migrate' to apply them.

我只想跑......

>>> python manage.py migrate

嗯是的就是这样。正如我上面所说，我做了相应的步骤......一次又一次地做错误状态的迁移，但每次我进入到createsuperuser步骤时，它将声明相同的错误 – Reiion

，因此您的数据库表必须位于createsuperuser看起来你的表不存在哪个是问题，没有用户表就不能创建超级用户。 –

迁移命令不应该自动创建表吗？它确实表示它“应用”了迁移。从admin，auth，contenttypes和session加上我的模型。我想知道这些警告是否会阻碍从迁移中创建表格。 – Reiion
