Related posts
-------------
This plugin adds the ``related_posts`` variable to the article's context.
By default, up to 5 articles are listed. You can customize this value by
defining ``RELATED_POSTS_MAX`` in your settings file::
RELATED_POSTS_MAX = 10
You can then use the ``article.related_posts`` variable in your templates.
For example::
{% if article.related_posts %}
<ul>
{% for related_post in article.related_posts %}
<li><a href="{{ SITEURL }}/{{ related_post.url }}">{{ related_post.title }}</a></li>
{% endfor %}
</ul>
{% endif %}
Your related posts should share a common tag. You can also use ``related_posts:`` in your post's meta data.
The 'related_posts:' meta data works together with your existing slugs::
related_posts: slug1, slug2, slug3, ... slugN
``N`` represents the ``RELATED_POSTS_MAX``.
Additionally, you can specify::
RELATED_POSTS_SKIP_SAME_CATEGORY = True
in your settings file. With this setting, ``article.related_posts`` will
contain only related posts from categories other than the original article's.
