刚学习django，模仿zabbix写个监控系统
环境：python 2.7.8
django 1.8.3
mysql 5.1.73
开发工具：eclipse
创建了一个my_cmdb的项目，在下面再创建一个web的app
设计表结构：
#_*_coding:utf-8_*_
import sys
reload(sys)
sys.setdefaultencoding("utf-8")

"""5.将设计的表添加到admin.py中
from django.contrib import admin import models # Register your models here. # Register your models here. admin.site.register(models.Idc) admin.site.register(models.Host) admin.site.register(models.Group) admin.site.register(models.UserProfile) admin.site.register(models.ServerStatus,) admin.site.register(models.Templates) admin.site.register(models.Services) admin.site.register(models.Items,) admin.site.register(models.ServiceList) admin.site.register(models.Graphs) admin.site.register(models.Operations) admin.site.register(models.Actions) admin.site.register(models.TrunkServers) admin.site.register(models.Conditions) admin.site.register(models.Formulas) admin.site.register(models.Operators) admin.site.register(models.TaskCenter) admin.site.register(models.TaskLog)
6.使用eclipse 直接makemigrations——migrate--run，启动程序
7.
Performing system checks...

March 04, 2016 - 06:17:27 Django version 1.8.3, using settings ‘my_cmdb.settings‘ Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C.
8.输入http://127.0.0.1:8000/admin/ 进入后台，但提示需要账号密码
9.在my_cmdb项目的目录下，python manage.py createsuperuser 创建admin的账号密码
10.进入后台
可以对数据操作了
