Django学习笔记（四）--admin的配置与应用

Adminadmin是django自带的功能强大的自动化数据管理界面被授权的用户可以直接在Admin中管理数据库（增、删、查、改）配置Admin创建超级用户 python manage.py createsuperuser访问后台管理系统：localhost:8000/admin (admin入口）修改setting.py中LANGUAGE_CODE='zh_Hans' (改成中文界面）配置应用：在应用下的admin.py中引入自身的models模块，加入代码  admin.site.register(models.***)admin.py

from django.contrib import admin
from . import models

# Register your models here.
admin.site.register(models.Article)

修改数据默认显示名称models.py

from django.db import models

# Create your models here.

class Article(models.Model):
title = models.CharField(max_length=32,default='Title')
content = models.TextField(null=True)

def __str__(self):
return self.title

这样就能显示标题了若不是python3，则修改__unicode__ 方法即可Admin 增强注册Admin配置类：class ArticleAdmin(admin.ModelAdmin)注册：admin.site.register(models.Article,ArticleAdmin)显示其他字段list_diplay = ('title','content')   （就是models里的字段名）admin.py中添加

from django.contrib import admin
from . import models

class ArticleAdmin(admin.ModelAdmin):
list_display = (  'title','content')

# Register your models here.
admin.site.register(models.Article,ArticleAdmin)

Admin过滤器list_diplay = ('pub_time',)tuple中只有一个成员，加逗号在models中Article类添加发布日期

from django.db import models

# Create your models here.

class Article(models.Model):
title = models.CharField(max_length=32,default='Title')
content = models.TextField(null=True)
pub_time = models.DateTimeField(null=True)

# def __str__(self):
#     return self.title

数据移植（才可以在数据库中显示）执行  

pythonmanage.py makemigrations

再执行

python manage.py migrate

生成了数据表

在admin.py中添加过滤器from django.contrib import adminfrom . import modelsclass ArticleAdmin(admin.ModelAdmin):list_display = ( 'title','content','pub_time')list_filter = ('pub_time',)# Register your models here.admin.site.register(models.Article,ArticleAdmin)
