当我点击http://127.0.0.1:8000/things/another-things/edit/是确定

然而当我点击编辑图像链接提交上传图像时，它表示没有文件已被选择？我不能上传图像

Answer 1

你必须检查

edit_thing_uploads.html

的文件权限，确保文件的访问。因为路径是正确的。 Django看不到它。

Answer 2

我知道为什么,,因为在edit_thing_uploads.html我错别字<form role="form" action="" method="post" enctype="multipart/form-data"> ---> <form role="form" action="" method="post" enctype="multipart/form\-data">
