当我点击http://127.0.0.1:8000/things/another-things/edit/时没问题

然而，当我点击编辑图像链接提交上传图片时，它说没有文件被选择？我无法上传图片

Answer 1

您必须检查

的文件权限

edit_thing_uploads.html

，确保该文件可访问。因为路径是正确的。而且Django看不到它。

Answer 2

我知道为什么，因为我在edit_thing_uploads.html中输错了<form role="form" action="" method="post" enctype="multipart/form-data"> ---> <form role="form" action="" method="post" enctype="multipart/form\-data">

无法上传图片
