Django viewsets 视图集与 router 路由实现评论接口开发

news 2025/9/14 6:43:35

正常来说遵循restful风格编写接口，定义一个类包含了 get post delete put 四种请求方式，这四种请求方式是不能重复的
例如:获取单条记录和多条记录使用的方式都是get，如果两个都要实现的话那么得定义两个类，因为在同一个类中不能有两个get
这里继承ViewSetMixin来解决该问题(根据是否传参)

comment/views
注意ViewSetMixin继承顺序要放在第一个

from django.http import JsonResponse
from django.shortcuts import render
from rest_framework.generics import GenericAPIView
from rest_framework.mixins import ListModelMixin, CreateModelMixin, RetrieveModelMixin, UpdateModelMixin, \DestroyModelMixin
from rest_framework.viewsets import ViewSetMixinfrom apps.comment.models import Comment
from apps.comment.serializers import CommentSerializer# Create your views here.
class CommentGenericAPIView(ViewSetMixin,GenericAPIView,ListModelMixin,CreateModelMixin,RetrieveModelMixin,UpdateModelMixin,DestroyModelMixin):queryset = Comment.objectsserializer_class = CommentSerializerdef single(self,request,pk):print("我是查询一个")return self.retrieve(request,pk)def my_list(self,request):print("我是查询多个")return self.list(request)def edit(self,request,pk):print("我是更新")return self.update(request,pk)def my_save(self,request):print("我是保存")return self.create(request)def my_delete(self,request,pk):print("我是删除")return self.destroy(request,pk)

comment/urls

from django.urls import path, re_path
from .views import CommentGenericAPIViewurlpatterns = [path("",CommentGenericAPIView.as_view({"get":"my_list","post":"my_save"   #保存})),re_path("(?P<pk>.*)",CommentGenericAPIView.as_view({"get":"single","post":"edit",  #编辑"delete":"my_delete"})),
]

comment/models

from django.db import models# Create your models here.
from django.db import modelsclass Comment(models.Model):user_id = models.IntegerField(blank=True, null=True)sku_id = models.CharField(max_length=255, blank=True, null=True)content = models.CharField(max_length=255, blank=True, null=True)user_image_url = models.CharField(max_length=255, blank=True, null=True)reference_name = models.CharField(max_length=255, blank=True, null=True)score = models.IntegerField(blank=True, null=True)nickname = models.CharField(max_length=255, blank=True, null=True)reply_count = models.CharField(max_length=255, blank=True, null=True)create_time = models.DateTimeField(blank=True, null=True)class Meta:managed = Falsedb_table = 'comment'

comment/serializers.py

from rest_framework import serializersfrom apps.comment.models import Comment
from apps.goods.models import Goodsclass CommentSerializer(serializers.ModelSerializer):class Meta:model = Commentfields = "__all__"
