我正在尝试将 Django 与 MongoDB 数据库连接。 为什么我在迁移时会收到这些警告?
【问题讨论】:
this 对您的问题有帮助吗? 【参考方案1】:Django 项目本身不支持 MongoDB,只能通过 Djongo 适配器支持。
这些模型/迁移使用 Djongo 目前不支持的某些 Django 核心功能,从错误消息中可以明显看出。
【讨论】:
其实这条消息来自Djongo
适配器,而不是Django
。
@Charnel 呃,是吗?
MongoDB isn't supported by the Django project itself, only via the Djongo adapter
- 我的意思是这个人已经在使用Djongo
采用者并且他们不是由Django
而是Djongo
提出的,可能是因为安装了错误的lib 版本。
我认为错误是由于 Djongo 不支持 Django 迁移所需的某些功能造成的。以上是关于Django MongoDB 迁移警告的主要内容,如果未能解决你的问题,请参考以下文章
