你做的有点奇怪。您正试图通过表单访问已上载的文件，该文件的URL存储在模型的一个字段中。问题的直接原因是表单字段不知道URL，它只有一个值。您需要通过底层表单实例来访问它，该实例作为概要文件传入，因此，
{{profile\u form.instance.pro\u pic.url}{{ user.profile.pro_pic.url }}
profile_form = ProfileForm(request.POST, request.FILES, instance=request.user.profile)
首先，您需要创建媒体\u根目录并按照指定将上传到目录
MEDIA_ROOT=os.path.join(BASE_DIR,'obs/media')
pro_pic = models.ImageField(upload_to='profilepic',blank=True)
<form method="post" enctype="multipart/form-data" class="hello">.
profile_form = ProfileForm(request.POST, instance=request.user.profile, request.FILES or None)
希望这会有所帮助。主页的视图是什么？它是否包含个人资料表单？@Daniel Roseman Yes我已经添加了负责主页的视图，我认为您需要使用
request.FILES<form method="post" enctype="multipart/form-data" class="hello">.
profile_form = ProfileForm(request.POST, instance=request.user.profile)
profile_form = ProfileForm(request.POST, instance=request.user.profile, request.FILES or None)
