django基础

1、pip安装（阿里云）

pip install -i https://mirrors.aliyun.com/pypi/simple django==2.1

2、建立项目

django-admin startproject app

3、添加模块

cd app
python manage.py startapp home

4、INSTALL APP配置

5、修改模板路径，创建template

'DIRS':[os.path.join(BASE_DIR,'templates').replace('\','/')],

6、mysql数据库配置

DATABASES = {
    'default':{
        'ENGINE':'django.db.backends.mysql',
        'NAME':'yzl_admin',
        'USER':'root',
        'PASSWORD':'root',
        'HOST':'127.0.0.1',
        'PORT':'3306'
    }
}

7、配置urls

from home.views import ListView,IndexView
from home import api

urlpatterns = [
    path('admin/', admin.site.urls),
    path('list/',ListView.as_view(),name="list"),
    path('',IndexView.as_view(),name="index"),
    path('api/client',api.api_client),
    path('api/nav',api.api_nav),
    path('api/shop',api.api_shop),
    path('api/img',api.api_image),
    path('api/content',api.api_content),
]

8、安装DjangoRestFrame

9、创建Models

10、创建api文件

from rest_framework.decorators import api_view
from rest_framework.response import Response
from home.models import Client,Nav,Shop,Image,Content
from home.toJson import Client_data,Nav_data,Shop_data,Img_data,Content_data

@api_view(['GET','POST'])
def api_client(request):
    client=Client.objects.all()
    client_data=Client_data(client,many=True)

    return Response({'data':client_data.data})

11、创建序列化文件

from rest_framework import serializers
from home.models import Client,Nav,Shop,Image,Content

class Client_data(serializers.ModelSerializer):
    class Meta:
        depth=1
        model=Client
        fields='__all__'
