django扩展django rest framework的使用

1：安装 django rest framework

pip install djangorestframework

2： settings.py的 INSTALLED_APPS 字段新增

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    
    "rest_framework", #新增
    "BookTest"
]

3：BookTest（自己的其中一个app）目录下创建serializers.py文件，内容如下：

from rest_framework import serializers
from .models import Book #自己的一个model类

class BookSerializer(serializers.ModelSerializer):

    class Meta:
        model = Book
        fields = '__all__'

4：创建视图集

BookTest/views.py

from rest_framework.viewsets import ModelViewSet
from .models import Book
from .serializers import BookSerializer

class BookView(ModelViewSet):

    queryset = Book.objects.all()
    
    serializer_class = BookSerializer

5：BookTest/urls.py修改路由

from rest_framework.routers import DefaultRouter
from . import views

urlpatterns = [

]

router = DefaultRouter()
router.register(r'books', views.BookView)
urlpatterns += router.urls

6：运行如下：
