Django Restful Framework

1. 下载安装

pip install djangorestframework

pip install markdown

pip install django-filter

或者直接从github上下载项目

git clone 

git@github.com:encode/django-rest-framework.git

2. 项目支持

打开自己的Django项目，在项目配置文件settings.py中，添加应用配置

INSTALLED_APPS =(

    …

    ‘rest_framework’

)

在项目根路由中，添加restframework认证路由

INSTALLED_APPS = [
    ......
    'rest_framework',
]

3. 操作案例

第一个案例，创建一个基于数据模型操作的api接口

完成对用户数据的读写操作

rest framework任何配置都是基于全局的REST_FRAMEWORK配置选项，打开你的Django项目配置文件settings.py，添加如下配置

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASS': [
        'rest_framework.permissions.DjangoModelPermissionOrAnonReadOnly'
    ]
}

备注：别忘记在你的INSTALLED_APPS中添加rest_framework哦！

接下来，在我们的主路由urls.py中，添加数据模型的处理方式，如下：

"""myrest_ex01 URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.conf.urls import url, include
from django.contrib.auth.models import User
from rest_framework import routers, serializers, viewsets


class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ['url', 'username', 'email', 'is_staff']


class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer


router = routers.DefaultRouter()
router.register(r'users', UserViewSet)

urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'^api_auth/', include('rest_framework.urls')),
]
