Django-站点管理

概述

  • 内容发布:负责添加、修改、删除内容,开发这些重复的功能是一件非常没有意义的事情,并且缺乏创造力。Django会根据定义的模型类来自动生成管理模块
  • 公共访问

配置Admin应用

  • 默认已经配置:'django.contrib.admin',

创建管理员用户

1
python manage.py createsuperuser

按顺序输入用户名、邮箱、密码

登陆

  • 启动服务
  • 在浏览器地址栏输入
    1
    http://127.0.0.1:8000/admin

    输入账号和密码

配置中文显示

1

3
LANGUAGE_CODE = 'zh-Hans'

TIME_ZONE = 'Asia/Shanghai'

修改settings.py文件

管理表数据

  • 将要管理的表添加到应用目录下的admin.py文件中进行注册

    from myApp.models import Student, Grade

    # Register your models here.
    admin.site.register(Student)
    admin.site.register(Grade)

自定义管理界面

  • ModelAdmin类

    • 是模型在Admin界面中的表现形式,通过定义ModelAdmin子类来定义模型在Admin界面的显示方式(admin.py)

  • 属性说明

    • 列表页属性
      • list_display:显示字段,可以点击进行排序
      • list_filter:过滤字段,过滤框出现在页面右侧
      • search_fields:搜索字段,搜索框会出现在列表上方
      • list_per_page:分页显示,确定每页有多少条数据
      • actions_on_top:执行动作框是否显示在上方
      • actions_on_bottom:执行动作框是否显示在下方
    • 添加、修改页属性
      • fields:属性排列顺序
      • fieldsets:属性分组,各组进行排序
      • 注意:以上两个属性不能同时使用
  • 关联对象(在添加班级的时候可以直接添加几个学生)

重写模板

  • templates目录下创建名为admin的目录
  • 找到默认模板的路径
    1
    C:\Users\xlg\AppData\Local\Programs\Python\Python36\Lib\site-packages\django\contrib\admin\templates\admin
  • 将想要修改的模板复制到自己模板目录下的admin目录下就可以进行自定义修改
