01.Django Admin基本使用

1.1 models.py创建表结构

from django.db import models

class User(models.Model):
    username = models.CharField(max_length=32,verbose_name='用户名')
    pwd = models.CharField(max_length=64,verbose_name='密码')
    ctime = models.DateTimeField(auto_now=True)
    ut = models.ForeignKey(to='UserType',to_field='id',verbose_name='用户类型')
    m2m = models.ManyToManyField("Group")
    def __str__(self):
        return self.username
    class Meta:
        verbose_name_plural = '用户表'

class UserType(models.Model):
    user_type_name = models.CharField(max_length=32)
    def __str__(self):
        return self.user_type_name

class Group(models.Model):
    group_name = models.CharField(max_length=32)
    def __str__(self):
        return self.group_name

1.2 admin.py中注册表

from django.contrib import admin
from app01 import models

class UserAdmin(admin.ModelAdmin):
    list_display = ('username','pwd','ut','ctime',)

admin.site.register(models.User,UserAdmin)
admin.site.register(models.UserType)
admin.site.register(models.Group)

02.Admin自定制常用参数

from django.contrib import admin
from app01 import models

class UserAdmin(admin.ModelAdmin):
    list_display = ('username','pwd','ut','ctime',)
    list_filter = ('source','consultant','date')     #过滤字段
    search_fields = ('qq','name')               #搜索匹配字段
    raw_id_fields = ('consult_course',)
    filter_horizontal = ('tags',)            #多对多字段显示
    list_per_page = 1                    #每页显示几条数据
    list_editable = ('source',)             #可编辑的字段
    readonly_fields = ('qq',)              #只读字段
    exclude = ('name',)                  # 添加和修改时那些界面不显示
    date_hierarchy = 'ctime'               # 详细时间分层筛选　
    actions = ['test_action',]              #之定义的action函数
    def test_action(self, request, arg2):      # 自定义action函数
        '''
        :param self:         crm.CustomerAdmin类本身
        :param request:      客户端request请求
        :param arg2:         前端选中的数据实例
        '''

admin.site.register(models.User,UserAdmin)
admin.site.site_header = '重写DjangoAdmin管理系统'      # 修改系统显示名称
admin.site.site_title = '我的后台管理界面'            # 修改页面 title
