Django我如何将Queryset返回到AJAX响应？

Question

Have a QuerySet object

userorder = UserOrder.objects.filter(
        user_id=user_id, is_closed=0)

response_data['uo'] = serializers.serialize('json', [ userorder, ])

But have Error

Traceback (most recent call last):
File "C:\Python27\lib\site-packages\django\core\handlers\exception.py", line 39, in inner
response = get_response(request)

我假设queryset.values()是您所需要的（ 注意它已经是一个列表 ）：

response_data['uo'] = serializers.serialize('json', userorder.values())
