admin增加数据

#admin.py
from django.contrib import admin
from host import models
# Register your models here.

class PermissionModelAdmin(admin.ModelAdmin):
    list_display = ['title', 'url', 'menu', 'parent', 'name']  # 展示的字段
    list_editable = ['url', 'menu', 'parent', 'name']  # 编辑的字段

class MenuModelAdmin(admin.ModelAdmin):
    list_display = ['title', 'icon', 'weight']  # 展示的字段
    list_editable = ['icon', 'weight']  # 编辑的字段

admin.site.register(models.Permission, PermissionModelAdmin)
admin.site.register(models.Role)
admin.site.register(models.UserInfo)
admin.site.register(models.Menu, MenuModelAdmin)

#创建为完表结构之后，需要创建superadmin用户，及后台admin管理
1.首先我们要新建一个用户名，用来登陆管理网站，可以使用如下命令：
    python manage.py createsuperuser
2.输入想要使用的用户名：
    Username (leave blank to use 'administrator'): admin
3.输入email：
    Email address: (在这里输入你的自己的邮箱帐号)
4.输入密码，需要输入两次，并且输入密码时不会显示出来：
    Password:
    Password (again):
5.当两次密码都相同的时候，就会提示超级帐号创建成功。
    Superuser created successfully.
6.运行服务：
    python manage.py runserver
7.浏览器地址栏输入：http://127.0.0.1:8000/admin
8.登录进入后台管理界面
