大佬教程收集整理的这篇文章主要介绍了Django内置Admin，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

Django内置的Admin是对于model中对应的数据表进行增删改查提供的组件，使用方式有：

Django内置Admin

messages django.contrib.sessions

模板的context_processors：
    django.contrib.auth.context_processors.auth
    django.contrib.messages.context_processors.messages

中间件：
    django.contrib.auth.middleware.AuthenticationMiddleware 
    django.contrib.messages.middleware.messageMiddleware</span></pre>

一. 配置路由






当前配置的路由可以创建一些路由映射关系：










二. 定制Admin
在admin.py中只需要讲Mode中的某个类注册，即可在Admin中实现增删改查的功能，如：

LPADding="0">

number1 index0 alt2">1
</td>

<td class="code">

<div class="container">

<div class="line number1 index0 alt2"><code class="python plain">admin.site.register(modelS.UserInfo)

</td>
</tr>

</table>

但是，这种方式比较简单，如果想要进行更多的定制操作，需要利用ModelAdmin进行操作，如：




</td>

<td class="code">

<div class="container">

<div class="line number1 index0 alt2"><code class="python plain">方式一：


<div class="line number2 index1 alt1"><code class="python spaces"><code class="python keyword">class <code class="python plain">UserAdmin(admin.ModelAdmin):


<div class="line number3 index2 alt2"><code class="python spaces"><code class="python plain">list_display <code class="python keyword">= <code class="python plain">(<code class="python string">'user'<code class="python plain">,

<code class="python string">'pwd'<code class="python plain">,)

<div class="line number5 index4 alt2"><code class="python spaces"><code class="python plain">admin.site.register(models.UserInfo,UserAdmin) <code class="python comments"># 第一个参数可以是列表

<div class="line number8 index7 alt1"><code class="python plain">方式二：

<div class="line number9 index8 alt2"><code class="python spaces"><code class="python decorator">@admin<code class="python plain">.register(models.UserInfo) <code class="python comments"># 第一个参数可以是列表

<div class="line number10 index9 alt1"><code class="python spaces"><code class="python keyword">class <code class="python plain">UserAdmin(admin.ModelAdmin):

<div class="line number11 index10 alt2"><code class="python spaces"><code class="python plain">list_display <code class="python keyword">= <code class="python plain">(<code class="python string">'user'<code class="python plain">,)

</td>

</tr>

</table>

ModelAdmin中提供了大量的可定制功能，如

1.list_display，列表时，定制显示的列。

LPADding="0"> number1 index0 alt2">1

number2 index1 alt1">2

number3 index2 alt2">3

number4 index3 alt1">4

number5 index4 alt2">5

number6 index5 alt1">6

</td>

</tr>

</table>

2.list_display_links，列表时，定制列可以点击跳转。

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2"><code class="python decorator">@admin<code class="python plain">.register(models.UserInfo)

<div class="line number2 index1 alt1"><code class="python keyword">class <code class="python plain">UserAdmin(admin.ModelAdmin):

<div class="line number3 index2 alt2"><code class="python spaces"><code class="python plain">list_display <code class="python keyword">= <code class="python plain">(<code class="python string">'user'<code class="python plain">,<code class="python string">'xxxxx'<code class="python plain">)

<div class="line number4 index3 alt1"><code class="python spaces"><code class="python plain">list_display_links <code class="python keyword">= <code class="python plain">(<code class="python string">'pwd'<code class="python plain">,)

</td>

</tr>

</table>

3.list_filter，列表时，定制右侧快速筛选。

LPADding="0"> number1 index0 alt2">1

number2 index1 alt1">2

number3 index2 alt2">3

number4 index3 alt1">4

number5 index4 alt2">5

number6 index5 alt1">6

number21 index20 alt2">21

number22 index21 alt1">22

number23 index22 alt2">23

number24 index23 alt1">24

number25 index24 alt2">25
