blog应用的数据库模型源码：

# This is an auto-generated Django model module.
    # You'll have to do the following manually to clean this up:
    #   * Rearrange models' order
    #   * Make sure each model has one field with primary_key=True
    #   * Make sure each ForeignKey has `on_delete` set to the desired behavior.
    #   * Remove `managed = False` lines if you wish to allow Django to create, modify, and delete the table
    # Feel free to rename the models, but don't rename db_table values or field names.

blog应用的功能函数views.py

from django.http import HttpResponse
    from blog.models import TItem
    
    
    def welcome(request):
        list = TItem.objects.all()
        for i in range(len(list)):
            print("序号：%s   值：%s" % (i + 1, list[i]))
        return HttpResponse("<h1>Welcome to Python3</he>")
    
    
    def insert(request):
        item = TItem(name='5')
        item.save()
        return HttpResponse('数据插入成功')
    
    
    def update(request):
        item = TItem.objects.get(id=1)
        item.name = '10'
        item.save()
        return HttpResponse("数据更新成功")
    
    
    def delete(request):
        item = TItem.objects.get(id=2)
        item.delete()
        return HttpResponse('数据删除成功')
    
    
    def select(request):
        list = TItem.objects.all()
        for i in range(len(list)):
            print("序号：%s   值：%s" % (i + 1, list[i].id))
        return HttpResponse('数据查询成功')

blog 应用的路由配置urls.py

from django.conf.urls import url
    from . import views
    
    urlpatterns = [
        url(r'^insert/', views.insert),
        url(r'^delete/', views.delete),
        url(r'^update/', views.update),
        url(r'^select/', views.select),
    ]
