使用tastypie资源将queryset转换为json [英] Convert a queryset to json using tastypie resource

问题描述

我有一个模特的tastypie资源。我还有一个看法，需要一个需要序列化并发送给客户端的查询器。我正在寻找一种方法来让味美资源处理查询的序列化和脱水。

我看到我可以传递一个对象到

  Resource.build_bundle（self，obj = None，data = None，request = None）] [1] 
  

创建一个捆绑包，然后将捆绑包传递给

  [Resource.full_dehydrate（self，bundle）] [2] 
  

，最后调用

  [Resource.serialize（self，request，data，format，options = None）] [3] 
  

对脱水数据。

但是，我想将完整的查询器转换为json而不仅仅是一个对象。也许我需要的是一种将完整的查询器转换为捆绑的方法。

任何帮助都赞赏！

解决方案

这也是我的错，但是我想在github上查看tastypie的代码后，我找到了答案。

这将使一堆的捆绑包。

  bundles = [Resource.build_bundle（obj = q，request = request）for q in Queryset] 
  

这将执行脱水。

  data = [Resource.full_dehydrate（bundle）for bundle in bundles] 
  

将执行序列化。

  Resource.serialize（无，数据，'application / json'），
  




I have a tastypie resource for a model. I also have a view which comes up with a queryset which needs to be serialised and sent to client. I am looking for a way to let tastypie resource handle the serialisation and dehydration of the queryset.

I see that I can pass a single object to

[Resource.build_bundle(self, obj=None, data=None, request=None)][1]

to create a bundle and then pass the bundle to

[Resource.full_dehydrate(self, bundle)][2]

and finally call

[Resource.serialize(self, request, data, format, options=None)][3]

on the dehydrated data.

But I want to convert full queryset to json and not just a single object. Maybe all I need is a way to convert full queryset to bundle.

Any help is appreciated!

解决方案

This was bugging me too, but I think I found the answer after looking through tastypie's code on github.

This will make a bunch of bundles.

bundles = [Resource.build_bundle(obj=q, request=request) for q in Queryset]

This will perform the dehydration.

data = [Resource.full_dehydrate(bundle) for bundle in bundles]

This will perform the serialization.

Resource.serialize(None, data, 'application/json'),
