这是我们《手把手教你用django搭建博客》系类的第三篇，这篇我们接上篇内容，解决如何实现首页文章分页的功能， 要实现分页要用到django的一个插件， 所以要先安装django_pagination，安装方式随意了，pip或者用自己的IDE功能来安装就可以，安装完毕后我们修改下配置文件就可以实现了，说实话，我在没用之前，真没见过实现分页如此简单的，好，废话不多说，我们开始，打开myblog下seettings.py文件，修改INSTALLED_APPS，MIDDLEWARE_CLASSES，TEMPLATE_CONTEXT_PROCESSORS这三段的内容，所以最后你的settings.py文件看起来应该像下面一样（算了，就把我的settings.py全部贴出来了吧）：

设置完settings.py文件后，我们需要再修改下我们的模板文件，打开index.html,修改内容如下：
|
1 2 3 4 5 6 7 8 9 10 11 12 |
{% extends 'base.html' %} {% load pagination_tags %} {% block content %} {% autopaginate posts 2 %} {% for post in posts %} <h2>{{ post.title }}</h2> <p>{{ post.timestamp|date:"1, F jS" }}</p> <p>{{ post.body }}</p> {% endfor %} <span style="padding-right: 60;float:right;list-style-type:none;">{% paginate %}</span> {% endblock %} |
默认的{% paginante %}是在左边，我加入了<span> 标签和行css样式，这样就移到了右边，这样就完成全部的分页功能了，什么？？是，你没听错，真的没有了，所以我开篇就说了，用django设置分页如此简单，平生我也是第一次见到，怎么？不信？不信启动项目，访问下：

看看是否已经实现了分页，这时候你看完，心头一乐，发现还TM实现了，转眼间你又心头一愣，哎，不对，这这跟开篇的第一张图不一样呀，我这分页是英文表示的，可你显示的中文：上一页，下一页呀，好吧，兄弟，算你好眼力，我们接下来就看看如何修改下默认的样式，打开pagination.html文件（在C:\Python27\Lib\site-packages\pagination\templates\pagination下），修改后如下：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
{% if is_paginated %} {% load i18n %} <div class="pagination"> {% if page_obj.has_previous %} <a href="?page={{ page_obj.previous_page_number }}{{ getvars }}{{ hashtag }}" class="prev">‹‹ {% trans "上一页" %}</a> {% else %} <span class="disabled prev">‹‹ {% trans "上一页" %}</span> {% endif %} {% for page in pages %} {% if page %} {% ifequal page page_obj.number %} <span class="current page">{{ page }}</span> {% else %} <a href="?page={{ page }}{{ getvars }}{{ hashtag }}" class="page">{{ page }}</a> {% endifequal %} {% else %} ... {% endif %} {% endfor %} {% if page_obj.has_next %} <a href="?page={{ page_obj.next_page_number }}{{ getvars }}{{ hashtag }}" class="next">{% trans "下一页" %} ››</a> {% else %} <span class="disabled next">{% trans "下一页" %} ››</span> {% endif %} </div> {% endif %} |
把对应英文的显示换成中文就可以了，这次是真的完成了。
好吧，到现在你可以去庆祝下你所学的东西了，既然这么高兴，你可以去喝二杯，当然也可以去请找妹子吃个饭，没准还能….你懂的。
