Django与json querydict和消息

Question

一旦收到请求django，我在db中查找并使用json.dumps发送dbresult到客户端，当然在应用serializers之后。现在，如果我需要以json格式向客户端发送任何失败消息或异常。我怎样才能做到这一点。我可以将消息追加到json。还是有更好的方法来做到这一点。

如果需要追加我怎么追加到我的JSON。这是我json data

products = Products.objects.all() 
    serialized = serializers.serialize("json", products) 
    json_data = json.dumps("json", serialized) 

    message = "got all products" # or "success" 

myjson输出无消息：

[{"pk": 1, "model": "Analysis.product", "fields": {"product": "Books", "company": 1, "product_desc": "None", "product_id": null, "user": 2}}, {"pk": 2, "model": "Analysis.product", "fields": {"product": "Moveis", "company": 1, "product_desc": "None", "product_id": null, "user": 2}}]

你可以做你自己的JSON对象，然后转储对象HttpResponse

to_json = { 
     "products": prodcuts, 
     "message": "got all products" 
    } 
serialized = serializers.serialize("json", to_json) 
return HttpResponse(simplejson.dumps(to_json), mimetype='application/json') 

希望帮助！
