我正在创建一个网站，供人们在Django中上传图片

应向代码中添加哪些内容，以便当页面用户使用以下通用查看功能上载图像时，数据库可以保存所有者，并将用户作为所有者与图像模型关联起来：

models.ForeignKey（UserProfile，on_delete=models.CASCADE）

用户上载图像时出现错误消息：

“User”对象没有属性“userprofile”

您可以通过覆盖

表单\u valid

方法来实现这一点。要获取当前用户，请使用

self.request.user

：

class ImageCreate (CreateView):
    model = Image
    fields = ['title', 'photo']

    def form_valid(self, form):
        form.instance.owner = self.request.user.userprofile
        return super().form_valid(form)
