推荐答案

Serializers allow通过在初始化序列化器时指定 partial=True 来部分更新.这就是 PATCH 请求的处理方式 默认在通用视图中.

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)

这将允许您更新序列化程序中的单个字段，或根据需要更新所有字段，而不受标准 PUT 请求的任何限制.

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.
