django.db.utils.OperationalError: attempt to write a readonly database
django.db.utils.OperationalError: attempt to write a readonly database
我正在尝试部署我的第一个网络应用程序。
我正在使用 django + docker + nginx + uwsgi。尝试先在我的笔记本电脑上部署。
当我 运行 我的 web 应用程序使用 django 服务器时一切正常，当我尝试使用 docker 启动没有 nginx 的 web 应用程序时它看起来也不错，但是当我使用使用 nginx 代理将数据写入数据库时出现问题（login/logout 用户会话）。如果我只去阅读页面，Web 应用程序可以很好地处理静态文件并在用户会话更改期间崩溃（登录 in/log 输出）
我的默认数据库权限问题
