pycharm配置django rest framework

安装django rest framework
```
pip install 
```

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',

]

连接mysql数据库

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

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__'

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')

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)),

]
