Usage with the Subcategory plugin
|
|
---------------------------------
|
|
|
|
If you want to get the neigbors within a subcategory it's a little different.
|
|
Since an article can belong to more than one subcategory, subcategories are
|
|
stored in a list. If you have an article with subcategories like
|
|
|
|
``Category/Foo/Bar``
|
|
|
|
it will belong to both subcategory Foo, and Foo/Bar. Subcategory neighbors are
|
|
added to an article as ``next_article_in_subcategory#`` and
|
|
``prev_article_in_subcategory#`` where ``#`` is the level of subcategory. So using
|
|
the example from above, subcategory1 will be Foo, and subcategory2 Foo/Bar.
|
|
Therefor the usage with subcategories is:
|
|
|
|
.. code-block:: html+jinja
|
|
|
|
<ul>
|
|
{% if article.prev_article_in_subcategory1 %}
|
|
<li>
|
|
<a href="{{ SITEURL }}/{{ article.prev_article_in_subcategory1.url}}">
|
|
{{ article.prev_article_in_subcategory1.title }}
|
|
</a>
|
|
</li>
|
|
{% endif %}
|
|
{% if article.next_article_in_subcategory1 %}
|
|
<li>
|
|
<a href="{{ SITEURL }}/{{ article.next_article_in_subcategory1.url}}">
|
|
{{ article.next_article_in_subcategory1.title }}
|
|
</a>
|
|
</li>
|
|
{% endif %}
|
|
</ul>
|
|
<ul>
|
|
{% if article.prev_article_in_subcategory2 %}
|
|
<li>
|
|
<a href="{{ SITEURL }}/{{ article.prev_article_in_subcategory2.url}}">
|
|
{{ article.prev_article_in_subcategory2.title }}
|
|
</a>
|
|
</li>
|
|
{% endif %}
|
|
{% if article.next_article_in_subcategory2 %}
|
|
<li>
|
|
<a href="{{ SITEURL }}/{{ article.next_article_in_subcategory2.url}}">
|
|
{{ article.next_article_in_subcategory2.title }}
|
|
</a>
|
|
</li>
|
|
{% endif %}
|
|
</ul>
