执行python manage.py迁移后，不是从我的models.py数据库中创建表能够从django_session等创建其他表。这里还有其他需要我遵循的东西吗？

After doing python manage.py migrate, tables are not created in database from my models.py it is able to create other tables from django_session etc. Is there anything else that I need to follow here ?

推荐答案

我面临着类似的问题Django 1.10中的问题，上述解决方案都不适合我。

I was facing a similar problem in Django 1.10 and none of the above solutions worked for me.

运行此命令最终有效：

python manage.py migrate --fake myappname zero

这将重置所有迁移（到第零状态），然后是：

This followed by :

python manage.py migrate myappname

为我创建了表。

如果您不想回滚到初始（零）状态，而是说迁移号0005（有效的最后一次迁移），则可以执行以下操作：

If you do not want to roll back to the initial(zero) state but say to the migration number 0005(the last migration that worked), you can instead do this:

python manage.py migrate --fake myappname 0005

然后继续进行实际迁移：

And then proceed with the actual migrate:

python manage.py migrate myappname
