如果我们想要使用序列化器对应的是Django的模型类,DRF为我们提供了ModelSerializer模型类序列化器来帮助我们快速创建一个Serializer类。 ModelSerializer与常规的Serializer相同,但提供了: 基于模型类自动生成一系列字段 包含默认的create()和update()的实现 1. 将对象转换为字典 -- 序列化 2. 验证的字典数据 -- 反序...
从序列化程序中动态删除字段的一种简单方法是向序列化程序添加以下代码:

raw querysets don't support pagination out of the box. Here's a snippet of the relevant code: queryset = CheckTraModelTotal.objects.raw(sql_query) page = RawQuerySetPaginator(queryset, 15) serializer = self.get_serializer(page, many=True) return self.get_paginated_response(serializer.data...
