当我使用Django admin时，我当前的代码非常有效。如果我输入Django admin并向用户添加一个映像，该映像将正常显示在系统上

但是我想将用户配置文件图像添加到我的系统中，但是当我转到editafoto.html页面并提交时，它不会将新图像保存到数据库中，不会出现错误，它只是不保存，也不会发生任何事情

有人能告诉我哪里出了问题吗？

您忘记在代码中添加

request.FILES

UserProfileForm(request.POST or None, request.FILES or None, instance=foto)

另外，请确保将

enctype=“multipart/form data”

添加到

标记中

<form action="{% url 'edita_foto' user.id %}" method="POST" enctype="multipart/form-data">

您忘记在代码中添加

请求.file

UserProfileForm(request.POST or None, request.FILES or None, instance=foto)

另外，请确保将

enctype=“multipart/form data”

添加到
