Django admin后台管理页面的常用设置
选择列表选项choices
# filename: models.pyfrom django.db import models# 例1 int类型：STATUS = ((0, 0),(1, 1))class Team1(models.Model):status = models.IntegerField('状态', choices=STATUS, default=1) #default状态默认为1# 例2 字符类型：class Team2(models.Model):team_name = models.CharField(max_length=40)TEAM_LEVELS = (('U09', 'Under 09s'),('U10', 'Under 10s'),('U11', 'Under 11s'),... #list other team levels)team_level = models.CharField(max_length=3, choices=TEAM_LEVELS, default='U11')
输入框
name = models.CharField('用户名', max_length=200, unique=True)remark = models.TextField('备注', null=True, blank=True)num = models.IntegerField('数字', null=True, blank=True, default=0)
时间
accountcreated = models.DateField('时间', null=True, blank=True) # 自己选时间 updated = models.DateField('更新时间', auto_now=True) # 自动更新时间created = models.DateField('创建时间', auto_now_add=True) # 自动更新时间
主键
id = models.AutoField(primary_key=True)
显示在页面
## filename: views.pyfrom django.shortcuts import renderfrom .models import Teamdef index(request):list_teams = Team.objects.filter(team_level__exact="U09")context = {'youngest_teams': list_teams}return render(request, '/best/index.html', context)## filename: best/templates/best/index.html<!DOCTYPE html><html lang="en"><head><meta charset="utf-8"><title>Home page</title></head><body>{% if youngest_teams %}<ul>{% for team in youngest_teams %}<li>{{ team.team_name }}</li>{% endfor %}</ul>{% else %}<p>No teams are available.</p>{% endif %}</body></html>
以format_html动态方式返回结果的函数
# 例1：def Job_detail(self):href = f'/job_detail/?query={self.job_name}&city={self.job_add}/'return format_html(f'<a href={href}>job</a>')Job_detail.short_description = 'Job_detail'#例2：class ImageColumn(tables.Column):def render(self, value):return format_html('<a href="/media/{0}" download>{0}</a>', value)
只写模型类、不写__str__：
写模型类、写__str__：
def __str__(self):return self.name
字段名默认为app_name， 而表明默认为app名+_类名，如果不想要默认的就要指定，如下：
class ItemForSale(models.Model):app_id = models.ForeignKey(App) app_name = models.CharField(verbose_name='应用名', max_length=32, db_column='对应的字段名') class Meta: db_table = 'ItemForSale' #对应的表名verbose_name = '用户名' #指定在admin管理界面中显示中文，单数形式的显示verbose_name_plural = '用户名'#复数形式的显示
整体代码如下：
from django.db import modelsfrom django.utils.html import format_htmlSTATUS = ((0, 0),(1, 1))class Accounts(models.Model):id = models.AutoField(primary_key=True)name = models.CharField('用户名', max_length=200, unique=True)job_add = models.CharField('地址', max_length=200, unique=True)status = models.IntegerField('状态', choices=STATUS, default=1)def __str__(self):return self.namedef Job_detail(self):href = f'/job_detail/?query={self.name}&city={self.job_add}/'return format_html(f'<a href={href}>Job_detail</a>')Job_detail.short_description = 'Job_detail'
后台顶部标题的修改：app/admin.py中设置
admin.site.site_title ='site_title'admin.site.site_header = 'site_header'admin.site.index_title='index_title'
更改后
