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django应用程序。

那是使用filer ，我什至已经在INSTALLED_APP元组中定义了它，如本答案所述。

我一次又一次地交换filer名称，以可能在我的防雷filer之前安装此应用程序，这样就可以避免此错误，但是当所有错误都部署在heroku上时，我会不断收到此错误。

当我尝试迁移数据库时，得到以下信息：

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

迁移完成之后？

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。
