我正在尝试将Django与MongoDB数据库连接。 为什么在迁移时会收到这些警告？

Answer 1

MongoDB并非Django项目本身支持的数据库，只能通过Djongo适配器使用。

这些模型/迁移使用了某些Django核心功能，而Djongo目前不支持这些功能，这从错误消息中很明显。

实际上，这些消息来自于 Djongo 适配器，而不是 Django。 - Charnel

@Charnel Er，是的？ - AKX

MongoDB并不是Django项目本身支持的，只能通过Djongo适配器来使用。我的意思是这个人已经在使用Djongo适配器了，而不是Django，可能是因为安装了错误的库版本。 - Charnel

我认为这些错误是由于Djongo不支持一些Django迁移所需的功能引起的。 - AKX
