<h1>为你的 Django 博客添加 Disqus 评论系统</h1>
<div class="read-more clearfix">

</div><!-- article -->
<div class="article-content">
<p>首先，先去 <a href="https://disqus.com/"> Disqus 官网</a>注册个账号啦.注册完账号之后去首页末尾<br/>
→API→Application，找到 DISQUS_API_KEY 一项，复制一下KEY，等下会用到。</p>
<span id="more"></span><!-- more -->
<hr />
<p>安装 Disqus ,依官方推荐，使用pip自动安装~</p>
<pre class=black>sudo pip install django-disqus</pre>
若是没有 pip 也不用着急，去<a href="http://pypi.python.org/pypi/django-disqus/">官方下载一份二进制包</a>，然后解压，进入目录安装
<pre class=black>python install setup.py</pre>
<hr />
<p>修改 setting.py ,在 INSTALLED_APPS 中添加 disqus 项并在文件末尾添加两项参数。其中一项就是刚才复制的KEY啦。</p>
<pre>
INSTALLED_APPS = (
...
'disqus',
)
DISQUS_API_KEY = 'FOOBARFOOBARFOOBARFOOBARFOOBARF'
DISQUS_WEBSITE_SHORTNAME = 'foobar'
</pre>
<hr />
<p>通过Django Shell 执行以下命令。恩里面的domain和name改成你自己的就好啦。</p>
<pre class="black">
$ python manage.py shell
Python 2.7.3 (default, Mar 18 2014, 05:13:23)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.contrib.sites.models import Site
>>> Site.objects.all()
[<Site: example.org>]
>>> s = Site.objects.all()[0]
>>> s.domain = 'foobar.com'
>>> s.name = 'foobar.com'
>>> s.save()
>>> Site.objects.all()
[<Site: foobar.com>]
</pre>
<p>我自己在这一步遇到了一个错误，执行<code>Site.objects.all()</code>的时候报错，提示<br/>
<pre class=black><br/>
ProgrammingError: (1146, "Table 'Blog.django_site' doesn't exist")<br/>
</pre><br/>
这是由于没有安装django.sites模块造成的。<br/>
只需要在 INSTALLED_APPS 中添加这一模块然后 syncdb就好了。<br/>
<pre><br/>
INSTALLED_APPS = (<br/>
...<br/>
'django.contrib.sites'<br/>
'disqus',<br/>
)<br/>
</pre><br/>
<pre class=black>python manage.py syncdb</pre></p>
<hr />
<p>修改模板文件，在指定位置添加 Disqus </p>
<pre>
{% load disqus_tags %}
{% disqus_show_comments %}
{% disqus_num_replies %}
{% disqus_recent_comments shortname num_items excerpt_length hide_avatars avatar_size %}
</pre>
<p>其中第一项必选，加载 disqus ，第二至第四项可选。</p>
<p>后三项分别是</p>
<ol>
<li>显示评论</li>
<li>显示评论数</li>
<li>显示最近评论。</li>
</ol>
<p>其中显示评论数是通过JS修改含data-disqus-identifier=“{{ object.id }}"属性的<a\>标签来显示的。所以记得加上哦。</p>
<p>以上，就是 Disqus 的安装啦</p>
