老师你好！请指点下。

启动时报错：AttributeError: type object 'UploadImageForm' has no attribute 'as_view'

相关代码是：class UploadImageForm(forms.ModelForm):
   class Meta:
       model = UserProfile
       fields = ['image']

class UploadImageView(LoginRequiredMixin,View):
   """
   用户修改头像
   """
   def post(self, request):
       image_form = UploadImageForm(request.POST, request.FILES, instance=request.user)
       if image_form.is_valid():
           pass
