In Django admin custom style

Django admin comes in a single display data is the style a little, we can show your own style definition data.

A custom data presentation style

1, when the secretary background check lists, lists both Publisher and time:

admin.py file

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)

Thus, it shows the following picture:

2, add a search box

admin.py

from django.contrib import admin


import models

class BookAdmin(admin.ModelAdmin):
    list_display = ('name','publisher','publication_date')
    search_fields = ( 'name', 'publisher__name') # Search '__' represents a related need to query other tables

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

In this way, there is a search box:

3, add filters

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)

In this way, the right of the admin page to add a filter

4, edit each row field

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;color:white">已出版</span>')
        if self.status=='publishing':
            format_td=format_html('<span style="padding:2px;color:white">未出版</span>')
        if self.status=='forbidden':
            format_td=format_html('<span style="padding:2px;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 = 'prevent publication'

class BookAdmin(admin.ModelAdmin):
    list_display = ( 'id', 'name', 'publisher', 'publication_date', 'status_color') # add functions newly defined in status_color model, shown in the admin
    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] option in the displayed #action

Results are as follows:

So that it can modify the batch
