Question

我是Django的初学者。我填写注册表时遇到问题。我无法上传任何图片。如果ImageField设置为required=true，则它永远不会被验证，无法提交。如果required=false，则可以提交，但图片永远不会保存在目标文件夹（模型）中。但是，我可以作为超级用户从管理面板上传图像。

也许图片没有保存......我迷路了。我在这里阅读了3天的帖子，但我还没找到任何解决方案。我看到了与我类似的问题，但采用了不同的方法，但尚未解决。 Django: upload image to form

感谢。

Answer 1

您必须在表单类

中添加request.FILES

form = UserRegistrationForm(request.POST)

还有form.photo = request.FILES['photo']

Answer 2

我认为也许您忘记将enctype="multipart/form-data"添加到表单中。
