RESTful 在Django框架中实现的插件：rest_framework
在Django框架中RESTful主要表现在序列化的实现、视图函数的实现和urls路由的实现，在这里我们可能会完全推翻Django基础知识中实现代码的方式。
1. 安装：
pip install restframework
2. 在Django中的配置：
1. settings.py中INSTALLED_APPS添加[‘rest-framework‘,]
2.在应用中创建Serializers.py
3.将模型序列化为JSON
Serializers中三个基础的序列化类:
3.1 。serializers.HyperLinkedModelSerializer：
# models.py from django.db import models class Books(models.Model): b_name = models.CharField(max_length=30) b_price = models.FloatField(default=1) def to_dict(self): return {‘id‘:self.id, ‘b_name‘:self.b_name, ‘b_price‘:self.b_price}
# urls.py from django.urls import include, path from rest_framework import routers from REST import views router = routers.DefaultRouter() router.register(r‘Books‘, views.BookViewSet) urlpatterns = [ path(‘‘, include(router.urls)), ]
from django.shortcuts import render # Create your views here. from rest_framework import viewsets from REST.models import Books from REST.serializers import BookSerializer class BookViewSet(viewsets.ModelViewSet): queryset = Books.objects.all() serializer_class = BookSerializer
# serializers.py from rest_framework import serializers from REST.models import Books class BookSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Books fields = (‘url‘, ‘b_name‘,‘b_price‘)
models.py : 建立模型
urls.py :建立路由
views.py :建立序列化类视图
serializers.py :序列化
3.2 。serializers.Serializer
class Person(models.Model): p_name = models.CharField(max_length=32) p_age = models.IntegerField(default=1) p_sex = models.BooleanField(default=False) class Meta: db_table = ‘Person‘
from django.urls import path from REST import views urlpatterns = [ path(‘person‘, views.PersonView.as_view()), ]
class PersonView(View): def post(self,request): p_name = request.POST.get(‘p_name‘) p_age = request.POST.get(‘p_age‘) print(‘*********‘,p_name) person = Person() person.p_name = p_name person.p_age = p_age print(‘***##***‘, p_name) person.save() person_serializer = PersonSerializer(person) return JsonResponse(person_serializer.data)
class PersonSerializer(serializers.Serializer): # 和模型中的字段对应 id = serializers.IntegerField(read_only=True) # 表示只读 p_name = serializers.CharField(max_length=32) p_age = serializers.IntegerField(default=1) p_sex = serializers.BooleanField(default=False) # 进行对象的创建 def create(self,validated_data): return Person.objects.create(**validated_data) # 对象的更新 def update(self, instance, validated_data): # 分别拿到对象，并对对象进行更新 instance.p_name = validated_data.get(‘p_name‘,instance.p_name) print(‘@@@@@@‘) instance.p_age = validated_data.get(‘p_age‘, instance.p_age) instance.p_sex = validated_data.get(‘p_sex‘, instance.p_sex) instance.save() return instance
3.3 。serializers.ModelSerializer
class StudentSerializer(serializers.ModelSerializer): class Meta: model = Students fields = (‘s_name‘, ‘s_age‘)
（省略了models.py,urls.py,views.py,和serializers.Serializer类似）ModelSerializer简单，常用！！！
