让Django在没有“字段"的情况下序列化对象场地 [英] Getting Django to serialize objects without the "fields" field

问题描述

因此，我正在使用Django编写后端Web服务来创建&使用JSON，而我的同事正在研究ExtJS4前端.我正在使用wadofstuff序列化程序，以便可以序列化嵌套对象.

So I am working on writing the backend web service using Django to create & consume JSON, and my colleague is working on the ExtJS4 frontend. I'm using the wadofstuff serializer so I can serialize nested objects.

我的同事在解析json时遇到问题，特别是Django将对象的字段放在字段"字段中.一个简短的例子:

My colleague is having trouble parsing the json, specifically that Django puts the fields for an object inside a "fields" field. A short example:

现在事物序列化的方式:

The way things are being serialized now:

{
  "pk":1,
  "model":"events.phone",
  "fields":{
     "person":1,
     "name":"Cell",
     "number":"444-555-6666"
  }
}

我想序列化它们以使ExtJS和我的开发人员感到高兴的方式:

The way I would like to serialize them to make ExtJS and my fellow developer happy:

{
  "pk":1,
  "model":"events.phone",
  "person":1,
  "name":"Cell",
  "number":"444-555-6666"
}

我们将需要序列化一些比这复杂得多的对象.

We will need to serialze some objects that are much more complicated than this however.

有什么办法可以手动编写序列化序列，以使Django或wadofstuff序列化序列不使用fields字段?

Is there any way short of writing my serializations by hand to make the Django or wadofstuff serializer not use a fields field?

推荐答案

自定义序列化的最佳方法是让Django首先序列化为Python字典.然后，您可以对自己喜欢的那些字典进行后处理，然后再将它们转储到JSON中:

The best way to customize your serialization is to get Django to serialize to Python dicts first. Then you can post-process those dicts however you like, before dumping them out to JSON:

# this gives you a list of dicts
raw_data = serializers.serialize('python', Phone.objects.all())
# now extract the inner `fields` dicts
actual_data = [d['fields'] for d in raw_data]
# and now dump to JSON
output = json.dumps(actual_data)
