Question

Django == 1.11.3，wagtail == 1.11.1

我在远程服务器上备份了我的PostgreSQL，并在我的本地服务器上进行了恢复，因此我可以获得所有更改的精确副本。我已经用这种方式做了很长时间，它总是像魅力一样。但是这一次，我做了恢复并得到了以下错误：

column wagtailcore_page.draft_title does not exist LINE 1: ...ore_page"."numchild", "wagtailcore_page"."title", "wagtailco...

我删除了我的数据库并恢复了新鲜但却没有做任何事情。我删除了所有迁移，执行--fake迁移以尝试重置，但没有删除;仍然得到错误。我对此感到茫然，可以使用一些反馈。谢谢。

这是我的跟踪文件：

Answer 1

恢复数据库备份后，您需要运行./manage.py migrate。在Wagtail 1.11中添加了draft_title，因此可能您的备份来自运行Wagtail 1.10或更早版本的站点。

（正在运行--fake与您想要的相反...它告诉Django 不运行任何未完成的迁移，包括添加draft_title的迁移列。）

Answer 2

错误是由于您没有迁移最新版本的wagtail。只需运行python manage.py migrate，当您看到它正在运行时，就会显示：

Running migrations:
Rendering model states ... DONE
Applying 
wagtailcore.0040_page_draft_title 
... OK

重新运行您的项目，您已完成。

Django列wagtailcore_page.draft_title不存在
