内联表单集中的图像字段未填充
我有这段代码：
vehicle = get_object_or_404(Vehicle, stock_number=stock_number)
if request.method == 'POST':
vehicle_form = VehicleForm(request.POST, instance=vehicle)
photos = PhotosFormSet(request.POST, request.FILES, instance=vehicle)
if vehicle_form.is_valid() and photos.is_valid():
vehicle = vehicle_form.save()
photos.save()
request.user.message_set.create(message='The vehicle "%s" was edited
successfully.' % vehicle.__str__())
return HttpResponseRedirect("/vehicles/details/%s/" % stock_number)
else:
vehicle_form = VehicleForm(instance=vehicle)
photos = PhotosFormSet(instance=vehicle)
return render_to_response('vehicles/vehicles-add-edit.html',
{'vehicle_form':vehicle_form, 'photos': photos,},
context_instance=RequestContext(request))
除了 PhotosFormSet 中的 ImageField 之外，表单均已正确初始化。

The forms are initialized correctly except the ImageField in PhotosFormSet.

当你说它没有初始化时你是什么意思？你的意思是用原始数据填充吗？
HTML 文件输入字段永远不会填充现有数据 - 这是浏览器限制，与 Django 无关。这是一项安全措施，旨在阻止恶意网站欺骗您从计算机上传任意内容。
What do you mean when you say it's not initialized? Do you mean populated with the original data?
HTML file input fields are never populated with existing data - this is a browser restriction, nothing to do with Django. It's a security measure, to stop malicious sites tricking you into uploading arbitrary content from your computer.
