Django后台

1、在models.py中新建新的class

coding:utf-8
from django.db import models

class Article(models.Model):
title = models.CharField(u'标题', max_length=256)
content = models.TextField(u'内容')

pub_date = models.DateTimeField(u'发表时间', auto_now_add=True, editable = True)
update_time = models.DateTimeField(u'更新时间',auto_now=True, null=True)

2、同步数据库，在数据库中新建对应的table

python manage.py makemigrations
python manage.py migrate

3、为后台创建一个超级管理员

python manage.py createsuperuser

4、修改admin.py

from django.contrib import admin
from .models import Article

admin.site.register(Article)

5、修改 blog 中的models.py

class Article(models.Model):

title = models.CharField(u'标题', max_length=256)
content = models.TextField(u'内容')

pub_date = models.DateTimeField(u'发表时间', auto_now_add=True, editable=True)
update_time = models.DateTimeField(u'更新时间', auto_now=True, null=True)

def __unicode__(self): # 在Python3中用 __str__ 代替 __unicode__
return self.title

6、打开服务器，登录后台

python manage.py runserver

7、在列表中显示与字段语段的其他内容

(1)、修改admin.py

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

class PersonAdmin(admin.ModelAdmin):
list_display = ('full_name',)

admin.site.register(Article,ArticleAdmin)
admin.site.register(Person,PersonAdmin)

(2)、修改models.py

class Person(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)

def my_property(self):
return self.first_name + ' ' + self.last_name
my_property.short_description = "Full name of the person"
full_name = property(my_property)

8、在admin界面添加新的功能

(1)、搜索功能 search_fields = [‘first_name’]

class PersonAdmin(admin.ModelAdmin):
list_display = ('full_name',)
search_fields = ['first_name']

(2)、筛选功能list_filter = (‘last_name’, )

class PersonAdmin(admin.ModelAdmin):
list_display = ('full_name',)
search_fields = ['first_name']list_filter = ('last_name', )
