视图和路由设置

同一个视图相应不同的方法

from django.db import models

# Create your models here.

class Book(models.Model):
    nid=models.AutoField(primary_key=True)
    name=models.CharField(max_length=32)
    price=models.DecimalField(max_digits=5,decimal_places=2)

    def __str__(self):
        return self.name

#!/usr/bin/env python 
# -*- coding: utf-8 -*-

from rest_framework import serializers
from app01 import models


class BookSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Book
        fields = '__all__'

from django.shortcuts import render

# Create your views here.
from app01 import models, mySer
from rest_framework.viewsets import ViewSetMixin
from rest_framework.views import APIView
from rest_framework.response import Response


class Book(ViewSetMixin, APIView):
    def get_all(self, request):
        response = {'status': 100, 'msg': '查询成功'}
        book_list = models.Book.objects.all()
        ser = mySer.BookSerializer(instance=book_list, many=True)
        response['data'] = ser.data

        return Response(response)

    def get_one(self, request, pk):
        response = {'status': 100, 'msg': '查询成功'}
        book_list = models.Book.objects.all().filter(pk=pk).first()
        if book_list:
            ser = mySer.BookSerializer(instance=book_list, many=False)
            response['data'] = ser.data

        else:
            response['status'] = 101
            response['msg'] = '查询失败'

        return Response(response)

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.Book.as_view({'get':'get_all'}) ),
    url(r'^books/(?P<pk>d+)',views.Book.as_view({'get':'get_one'}) ),


]

在视图函数中,如果将

return Response (response)  转化为Json格式字符串,如下

return JsonResponse(response,safe=False)

自动生成路由视图验证

from django.db import models

# Create your models here.

class Book(models.Model):
    nid=models.AutoField(primary_key=True)
    name=models.CharField(max_length=32)
    price=models.DecimalField(max_digits=5,decimal_places=2)

    def __str__(self):
        return self.name

from django.conf.urls import url,include # include用作路由分发
from django.contrib import admin
from app01 import views

from  rest_framework import routers
# 实例化产生一个对象
router=routers.DefaultRouter()
# 传两个参数
router.register('books',views.Book)

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    # url(r'^books/$',views.Book.as_view({'get':'get_all'}) ),
    # url(r'^books/(?P<pk>d+)',views.Book.as_view({'get':'get_one'}) ),
    url(r'',include(router.urls))
    


]

from app01 import models, mySer
from rest_framework.views import APIView
from rest_framework.viewsets import ModelViewSet

# 自动生成路由
class Book(ModelViewSet, APIView):
    queryset = models.Book.objects.all()
    serializer_class = mySer.BookSerializer

手写配置文件

有两套配置文件,默认配置,用户的配置

如果某个字段,用户配置了,就用用户的,如果没配置,就用默认的
