【问题描述】：

有一个 QuerySet 对象

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

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

但有错误

Traceback (most recent call last):

response = get_response(request)

想在客户端获取json对象与他一起工作

【解决方案1】：

我假设 queryset.values() 是您需要的 (note it is already a list)：

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

【讨论】：

addresses = UserAddress.objects.filter(user_id=user_id) response_data['addresses'] = serializers.serialize('json',addresses.values()) ///////concrete_model = obj._meta.concrete_model AttributeError: 'dict' 对象没有属性 '_meta'
你能用json.dumps代替serializers.serialize吗？
