https://www.django-rest-framework.org/tutorial/quickstart/#serializers -- 序列化
一个 例子
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘books/(d+)/‘, views.BookHandle.as_view()), url(r‘books/‘, views.BookHandle.as_view()), ]
class BookHandle(APIView): # 获取所有书籍 def get(self, request,id=None): if id: books_obj_list = models.Book.objects.filter(id=id) else: books_obj_list = models.Book.objects.all() book_se = BookSerializer(books_obj_list, many=True) # 要点 return Response(book_se.data)
查询全部和带参数的查询 --
from django.shortcuts import render from app01 import models from rest_framework.views import APIView from rest_framework import serializers from rest_framework.response import Response # 响应 class BookSerializer(serializers.ModelSerializer): class Meta: model = models.Book fields = ‘__all__‘ # exclude = (‘user‘,) 排除某些字段的方法 fields=[‘‘,‘‘]列表
class BookHandle(APIView): # 获取所有书籍 def get(self, request,id=None): if id: books_obj_list = models.Book.objects.filter(nid=id) else: books_obj_list = models.Book.objects.all() book_se = BookSerializer(books_obj_list, many=True) # 要点 return Response(book_se.data) def post(self, request): cs = BookSerializer(data=request.data,many=False) if cs.is_valid(): cs.save() # create 新建 return Response(cs.data) else: return Response(cs.errors) class SBookHandle(APIView): # 更新数据 def put(self,request,id): old_obj = models.Book.objects.filter(pk=id).first() # querySet cs = BookSerializer(data=request.data,many=False,instance=old_obj) if cs.is_valid(): cs.save() # 更新 update return Response(cs.data) else: return Response(cs.errors) def delete(self,request,id): models.Book.objects.filter(pk=id).delete() # 删除 return Response(‘‘) def get(self,request,id): books_obj_list = models.Book.objects.get(pk=id) # model 类型 book_se = BookSerializer(books_obj_list,many=False) return Response(book_se.data)
from django.conf.urls import url from django.contrib import admin from app01 import views urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘books/$‘, views.BookHandle.as_view()), # 不带参数的 url(r‘books/(d+)/‘, views.SBookHandle.as_view()), # 带参数的 ]
