Django中Admin样式定制

Django自带的admin在展示数据是样式有点单一,我们可以自己定义数据的展示样式。

一、自定义数据展示样式

1、后台查询书记列表时,同时列出出版社和出版时间:

admin.py文件

from django.contrib import admin

import models

class BookAdmin(admin.ModelAdmin):
    list_display = ('name','publisher','publication_date')    #展示

admin.site.register(models.Author)
admin.site.register(models.Publisher)
admin.site.register(models.Book,BookAdmin)

这样,展示效果如下图:

2、添加搜索框

admin.py

from django.contrib import admin


import models

class BookAdmin(admin.ModelAdmin):
    list_display = ('name','publisher','publication_date')
    search_fields = ('name','publisher__name')   #搜索,'__'表示需要关连到其他表中查询

admin.site.register(models.Author)
admin.site.register(models.Publisher)
admin.site.register(models.Book,BookAdmin)

这样,就有搜索框了:

3、添加过滤器

admin.py

from django.contrib import admin

import models

class BookAdmin(admin.ModelAdmin):
    list_display = ('name','publisher','publication_date')
    search_fields = ('name','publisher__name')
    list_filter = ('name','publisher','publication_date')   #过滤

admin.site.register(models.Author)
admin.site.register(models.Publisher)
admin.site.register(models.Book,BookAdmin)

这样,在admin页面的右侧就添加了一个过滤器

 

4、编辑每行字段

admin.py

from django.contrib import admin

import models

class BookAdmin(admin.ModelAdmin):
    list_display = ('id','name','publisher','publication_date')
    search_fields = ('name','publisher__name')
    list_filter = ('name','publisher','publication_date')
    list_editable = ('name','publisher','publication_date')    #可编辑的字段,注意,默认第一个字段不可编辑,因此添加'id'为第一个字段

admin.site.register(models.Author)
admin.site.register(models.Publisher)
admin.site.register(models.Book,BookAdmin)

效果如下:

5、设置每页显示的条数

admin.py

BookAdmin类中添加

list_per_page = 10

6、如果选项太多,可以先搜索,然后再添加

admin.py

filter_horizontal = ('authors',)

现实效果为:

 

二、Admin中Actions

给book新添加一个状态,表示出版和未出版,让其显示在admin里书籍的页面中。

1、在models中book类下添加status字段

class Book(models.Model):
    name = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)
    publisher = models.ForeignKey(Publisher)
    publication_date = models.DateField()

    status_choices=(
        ('published','已出版'),
        ('publishing','未出版'),
        ('forbidden','禁止出版'),
    )

    status = models.CharField(choices=status_choices,max_length=32,default='publishing')    #default字段必须添加,否则同步数据库会出错,默认为未出版

    def __unicode__(self):
      return self.name
    class Meta:
        verbose_name_plural='书籍名称'

2、同步数据库

sudo python manage.py makemigrations

sudo python manage.py migrate

然后在amdin中book信息显示叶就多了status的选项:

3、显示数据信息时,将状态显示出来

admin.py

class BookAdmin(admin.ModelAdmin):
    list_display = ('id','name','publisher','publication_date','status')

默认每本书的状态都是'未出版',如果现在要批量修改为'已出版'或者'禁止出版',就要使用action了。

在actions中添加已出版和禁止出版选项,然后不同的状态显示不同的背景颜色。

models.py


#!_*_ coding:utf-8 _*_
from __future__ import unicode_literals
from django.db import models
from django.utils.html import format_html #format_html是将html代码传给admin时依html格式显示,否则只显示本身字符串

class
Book(models.Model): name = models.CharField(max_length=100) authors = models.ManyToManyField(Author) publisher = models.ForeignKey(Publisher) publication_date = models.DateField() status_choices=( ('published',u'已出版'), ('publishing',u'未出版'), ('forbidden',u'禁止出版'), ) status = models.CharField(choices=status_choices,max_length=32,default='publishing') def __unicode__(self): return self.name class Meta: # 显示中文 verbose_name_plural=u'书籍名称' def status_color(self): if self.status=='published': format_td=format_html('<span style="padding:2px;background-color:yellowgreen;color:white">已出版</span>') if self.status=='publishing': format_td=format_html('<span style="padding:2px;background-color:pink;color:white">未出版</span>') if self.status=='forbidden': format_td=format_html('<span style="padding:2px;background-color:orange;color:white">禁止出版</span>') return format_td #将html样式传递给admin展示页面 status_color.short_description='status' #admin展示时名称为status(一个别名)

admin.py

def make_published(modelAdmin,request,queryset):      #queryset是选中的对象的集合
    queryset.update(status='published')
    make_published.short_description='出版'

def make_forbidden(modelAdmin,request,queryset):
    queryset.update(status='forbidden')
    make_forbidden.short_description='禁止出版'

class BookAdmin(admin.ModelAdmin):
    list_display = ('id','name','publisher','publication_date','status_color')   #添加model中新定义的函数status_color,在admin中显示出来
    search_fields = ('name','publisher__name')
    list_filter = ('name','publisher','publication_date')
    list_editable = ('name','publisher','publication_date')
    filter_horizontal = ('authors',)
    actions = [make_published,make_forbidden]   #action中显示的选项

效果如下:

这样就可以批量的修改了。
