在 heroku 上迁移 Django 应用程序：关系“filer_image”不存在

Question

我正在尝试在 heroku 上部署我的 django 应用程序。

那个使用filer，我什至在INSTALLED_APP元组中定义了它，就像in this answer所说的那样。

我一次又一次地更换 filer 名称，以便可能在我之前安装此应用程序，这样我就可以避免这个错误，但是当它全部部署在 heroku 上时，我一直收到这个错误。

当我尝试迁移数据库时，我得到了这个：

Traceback (most recent call last):

知道问题出在哪里吗？

我的 Django 版本是 1.8.5

Answer 1

您是否尝试过运行：

python manage.py syncdb

迁移完成后？

编辑： 如果您对架构进行了任何更改，您还需要运行：

python manage.py schemamigration appname --auto

然后再次迁移。
