Manage.py 迁移从未在 Aldryn 项目中奏效——不可能很好，对吧？
Manage.py migration hasn't ever worked in Aldryn project -- can't be good, right?
过去几周，我在 Aldryn 网站上工作时偶尔会尝试 运行 python manage.py migrate，但从未奏效。它并没有太困扰我，但我认为它可能应该如此（我对 Django CMS 及其方法还很陌生，如果我现在不让它工作，恐怕以后会影响到我）。这是我在 运行 执行命令时得到的输出：

我知道 Python 中的 NoneType 情况意味着正在调用的东西不存在，或者没有正确定义，它似乎指向这里的 NGINX 配置，但我我不知道如何解决它。有人在其他地方的线程上（不记得在哪里）建议有人通过完全摆脱涉及 NGINX 的代码段来解决基本相同的问题，但是......我需要那个东西！这是 aldryn_config.py 文件中 aldryn-django 部分的代码（我认为没有人希望我 post 整个文件，但如果有帮助我会编辑它):

非常感谢您阅读本文 - 任何建议都会很棒！我喜欢前端编辑，但如果您不能 CSS 它就不是很有用了！我想我可以使用 git（git 和 docker 都在没有迁移命令工作的情况下工作，这就是我推迟这么久的原因），但我怀疑我缺乏迁移导致我的虚拟环境出现问题，这最终可能成为一场噩梦：/
看起来您是从本地机器 运行ning python manage.py migrate 而不是从 docker 容器内部。
容器路径不同（例如源代码位于 /app），所有需要的要求都已安装，并且 postgres 数据库已链接并可用。
试试这个：
docker-compose run --rm web python manage.py migrate
它的作用是：
docker-compose：该命令根据同目录docker-compose.yml文件中的配置进行docker操作run：创建并运行一个新容器--rm：命令完成后删除容器（因为这是一次性命令，所以保留它没有意义）web：从 docker-compose.ymlweb”服务
python manage.py migrate：在容器
也可以运行bash作为命令。这将在容器内为您提供交互式提示。
