admin后台管理可以帮助你快速的实现已经注册了的模型表数据的增删改查
1.在项目文件夹的admin.py文件中注册你要操作的模型表
2.创建超级管理员,登录后台进行数据的管理
admin.py:
# 注册模型表用的方法 admin.site.register(模型表)
models.py
class Meta: verbose_name_plural = ‘表名‘ # admin后台中文显式表名
创建超级管理员 createsuperuser
django admin会自动给注册了的模型表生成起码四条url(增删改查)
http://127.0.0.1:8000/admin/app01/userinfo/ 展示数据 http://127.0.0.1:8000/admin/app01/userinfo/add/ 添加数据 http://127.0.0.1:8000/admin/app01/userinfo/2/change/ 编辑数据 http://127.0.0.1:8000/admin/app01/userinfo/2/delete/ 删除数据 http://127.0.0.1:8000/admin/app01/article/ 展示数据 http://127.0.0.1:8000/admin/app01/article/add/ 添加数据 http://127.0.0.1:8000/admin/app01/article/2/change/ 编辑数据 http://127.0.0.1:8000/admin/app01/article/2/delete/ 删除数据
1.list_display:控制展示字段信息(不能放多对多外键字段) 2.list_display_links:控制跳转链接 3.search_fields:多条件的或查询 页面上会出现一个搜索框 4.list_filter:过滤 (推荐放外键字段) 右侧过滤栏 5.actions:批量处理函数 def patch_init(self,request,queryset): queryset.update(...) patch_init.short_description = ‘函数注释‘ actions = [patch_init,]
