Adding database to Mezzanine project produces "sqlite3.OperationalError: no such table: django_site"
Adding database to Mezzanine project produces "sqlite3.OperationalError: no such table: django_site"
我正在尝试将第三方数据库添加到 Mezzanine 4.2.3 项目(根据 requirements.txt
,它使用 Django 1.10.8)。它由名为 food_crud
的应用程序使用。但是,它会产生此错误:sqlite3.OperationalError: no such table: django_site
.
我读过的大多数解决方案都针对 makemigrations
和 migrate
。少数人说要将 django.contrib.sites
添加到 INSTALLED_APPS
。我都试过了。

同样的项目目录布局及其各种设置(包括数据库设置)与 Django 2.0 项目配合良好。我在这个夹层项目中复制了它们,但编辑了名称以适合它。我错过了什么?
您的路由器将模型硬编码为电影,这并不奇怪意味着它始终与 food_crud 应用匹配。所以所有数据库请求都被路由到您的 sqlite 数据库。
不要那样做;删除 model
变量的覆盖。
