[基本上，当我查看inspect element中的“网络”选项卡时，我看到POST request已发送并且form数据有效，但是instance对象没有保存
class UpdateProfile(UpdateView):
template_name = 'dashboard/edit-profile.html'
form_class = UserForm
success_url = None
def get_object(self, queryset=None):
return User.objects.get(username=self.kwargs['username'])
def form_valid(self, form):
self.instance = form.save(commit=False)
self.instance.user = self.get_object()
self.instance.save()
return render(self.request, self.template_name, self.get_context_data())
我试图通过从instance获取数据直接将get_object中的数据分配给模型，但仍然没有效果。

所以我的问题是，由于使用Pillow库，无法正确上传图像。这是我为了使其工作而进行的更改
from PIL import Image
def save_profile_image(instance, filename):
name = filename.split('.')[0]
if instance:
im = Image.open(filename)
im.save(im.filename, quality=100)
return '{}/{}'.format(instance.id, filename)
