我將我的 Django 專案遷移到了新的生產服務器。在以前的生產服務器上，一切正常。遷移時，我升級到了 Ubuntu 20.04 和 Django 4.0.3。現在一切都恢復正常了，除了上傳檔案。
當我嘗試創建 Invoice 物件的實體時，它可以作業，只要我不嘗試將檔案與它一起上傳。添加帶有檔案的發票會出現以下錯誤：

該檔案已上傳到正確的（cifs 掛載）檔案夾，但由于某種原因，無法將包含檔案鏈接的物件實體添加到資料庫中？
我想問題是某種許可問題。我嘗試通過將所有內容設定為 777 來解決這個問題，所以我至少可以看看這是否解決了問題，但事實并非如此。/var/www/html/media 的檔案夾權限目前為：
drwxrwxrwx 2 root root 0 Mar 17 08:57 invoices
chown doesn't work for some reason (I read about this having something to do with the cifs mount?), but var-www wasn't the owner of the invoices folder on the previous server either, and that worked fine...
Any help would be very much appreciated!
uj5u.com熱心網友回復：
我找到了解決方案。
我必須將uid=www-data,forceuid 添加到 cifs mount 命令。apache 用戶沒有正確的權限。
（然后卸載，再次安裝）
