如何使用Django Rest Framework PATCH单个字段？ [英] How to PATCH a single field using Django Rest Framework?

问题描述

我有一个具有许多字段的模型MyModel，我想使用PATCH方法更新一个字段'status'。我正在使用基于类的视图。有没有办法实施PATCH？

解决方案

序列化器允许 partial = True 进行部分更新。这是 PATCH 请求被默认处理 通用视图。

  serializer = CommentSerializer（comment，data = request.data，partial = True）
  

这将允许您更新序列化程序或所有字段中的各个字段（如果需要），而没有任何标准的$ code> PUT 请求。

I have a model 'MyModel' with many fields and I would like to update a field 'status' using PATCH method. I'm using class based views. Is there any way to implement PATCH?

解决方案

Serializers allow partial updates by specifying partial=True when initializing the serialzer. This is how PATCH requests are handled by default in the generic views.

serializer = CommentSerializer(comment, data=request.data, partial=True)

This will allow you to update individual fields in a serializer, or all of the fields if you want, without any of the restrictions of a standard PUT request.
