Django 的css和js压缩插件：django_compressor

作者：Wally Yu

今天尝试了django_conpressor，一个在django框架中压缩css和js的插件，灰常有用

我把它加载在我的base的HTML template中，原来未经压缩的css和js是：

<link rel="stylesheet" href = "include/style.css" type="text/css">	
<link rel="stylesheet" href = "include/demo_page.css" type="text/css">
<link rel="stylesheet" href = "include/demo_table.css" type="text/css">


<script type="text/javascript" src="include/CloudTesting.js"></script>
<script src='include/jquery.min.js' type='text/javascript'></script> 
<script type='text/javascript' src='include/jquery.dataTables.js'></script>

压缩后会变成：

<link rel="stylesheet" href="include/CACHE/css/31b7bf7183d6.css" type="text/css" />
<script type="text/javascript" src="include/CACHE/js/3b54f0a1ee64.js"></script>

具体的做法：

详细的参见官方说明：http://django_compressor.readthedocs.org/en/latest/quickstart/

自己整理的关键步骤：

1. 安装：

pip install django_compressor

2. 添加到setting.py中：

INSTALLED_APPS = (
    # other apps
    "compressor",
)

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    # other finders..
    'compressor.finders.CompressorFinder',
)

3. 在settings.朋友中加入一些必要的配置：

COMPRESS_ROOT = 'Templates/include/'
COMPRESS_URL = 'include/'
COMPRESS_ENABLED = True

4. 使用起来很方便：

{% load compress %}
{% compress css %}
<link rel="stylesheet" href = "include/style.css" type="text/css">	
<link rel="stylesheet" href = "include/demo_page.css" type="text/css">
<link rel="stylesheet" href = "include/demo_table.css" type="text/css">
{% endcompress %}
{% compress js %}
<script type="text/javascript" src="include/CloudTesting.js"></script>
<script src='include/jquery.min.js' type='text/javascript'></script> 
<script type='text/javascript' src='include/jquery.dataTables.js'></script>
{% endcompress %}

一切搞定了，运行起来就是压缩后的效果了

注意：

COMPRESS_URL一定要以“/”结尾，否则会报“django.core.exceptions.ImproperlyConfigured: URL settings (e.g. COMPRESS_URL) mu
st have a trailing slash”这样的错
