pycharm配置django rest framework

1. 安装django rest framework

   pip install 

2. 添加rest_framework app  在settings.py
   

   INSTALLED_APPS = [
       'django.contrib.admin',
       'django.contrib.auth',
       'django.contrib.contenttypes',
       'django.contrib.sessions',
       'django.contrib.messages',
       'django.contrib.staticfiles',
   　　 //添加 rest_framework 应用，在你自己创建的app上面
       'rest_framework',
       'devops',
   ]

3. 连接mysql数据库
   请参考这个链接
4. 编辑model，创建ORM模型
   

   from django.db import models
   class SystemBaseInfo(models.Model):
       # 系统IP地址
       sip = models.GenericIPAddressField('sip', protocol='both', blank=True, null=True, default='0.0.0.0')
       # 带外管理IP地址
       mip = models.GenericIPAddressField('mip', protocol='both', blank=True, null=True, default='0.0.0.0')
       # 隶属业务线
       service_line = models.CharField('service_line', max_length=32, default='none')
       # 业务类别
       service_class = models.CharField('service_class', max_length=32, default='none')
   
   // 检查ORM模型有没有错误
   python manage.py makemigrations
   // 执行变更
   python manage.py migrate

5. 创建序列化文件，在你的应用下面 serializers.py
   

   from rest_framework import serializers
   from devops import models
   
   # 将serializers和model连接起来
   class SystemBaseInfo(serializers.HyperlinkedModelSerializer):
       class Meta:
           model = models.SystemBaseInfo
           fields = '__all__'

6. 在views.py 创建viewset
   

   from django.shortcuts import render, HttpResponse
   
   from rest_framework import viewsets
   from devops import models
   from devops import serializers as ss
   
   
   # 这个文件的作用是querysets和model instances这些复杂的数据结构转化为native Python 
   # 以便于以json,xml或其它内容类型的形式render出去。
   
   class SystemBaseInfo(viewsets.ModelViewSet):
       queryset = models.SystemBaseInfo.objects.all()
       serializer_class = ss.SystemBaseInfo
   
   def index(request):
       return HttpResponse('ok')

7. 配置urls.py
   

   """autoever URL Configuration
   
   The `urlpatterns` list routes URLs to views. For more information please see:
       https://docs.djangoproject.com/en/3.1/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.urls import path
   from devops import views as devops
   
   # 新增---导入库
   from django.conf.urls import url, include
   from rest_framework import routers, serializers, viewsets
   
   # 新增--添加router
   router = routers.DefaultRouter()
   router.register('systeminfo', devops.SystemBaseInfo)
   
   urlpatterns = [
       path('admin/', admin.site.urls),
       path('', devops.index),
       path('index/', devops.index),
       # 新增
       path('api-auth/', include('rest_framework.urls', namespace='rest_framework')),
       path('api/v1/', include(router.urls)),
   ]
