Django REST框架:非模型序列化程序
Django REST框架:非模型序列化程序
提问于 2012-11-28 18:35:23
我是Django REST框架的初学者，需要你的建议。我正在开发一个web服务。服务必须提供到其他服务的REST接口。我需要实现的REST接口并不直接使用我的模型(我指的是get、put、post、delete操作)。相反，它为其他服务提供了一些计算结果。在请求时，我的服务进行一些计算并返回结果(不将结果存储在自己的数据库中)。
下面是我对REST接口如何实现的理解。如果我错了，请纠正我。
- 创建进行计算的类。将其命名为'CalcClass‘。CalcClass在其工作中使用了这些模型。
- Params necessary for the calculations are passed to the constructor.
- Implement the calc operation. It returns results as 'ResultClass'.
- Create ResultClass。
- Derived from object.
- It just only has attributes containing the calc results.
- One part of the calc results is represented as tuple of tuples. As I understand, it would be better for further serialization to implement a separate class for those results and add list of such objects to ResultClass.
用于ResultClass.的
- 创建序列化程序
- Derive from serializers.Serializer.
- The calc results are read-only, so use mostly Field class for fields, instead of specialized classes, such as IntegerField.
- I should not impl save() method neither on ResultClass, nor on Serializer, because I am not going to store the results (I just want to return them on request).
- Impl serializer for nested results (remember tuple of tuples mentioned above).
- 创建视图以返回计算结果。
- Derive from APIView.
- Need just get().
- In get() create CalcClass with params retrieved from the request, call its calc(), get ResultClass, create Serializer and pass the ResultClass to it, return Response(serializer.data).
- URLs
- There is no api root in my case. I should just have URLs to get various calc results (calc with diff params).
- Add calling format\_suffix\_patterns for api browsing.
我错过了什么吗？这种方法总体上是正确的吗？
