URLs and Links

Linking to other pages in templates is achieved through the |url and |asseturl filters. These two filters will ensure that the links that are generated are automatically relative to the current page so they will work correctly anywhere you host the page. They also deal with URL paths that have been changed through configuration.

url Filter

The url filter is the most useful filter for URL generation and it comes in two flavors. It takes one optional argument which is the alt if it should differ from the current one (see Alternatives). The filter can be applied to either a string or a Record object.

Basic Navigation

This is an example of how to just link to some specific pages that exist. Because the path starts with a slash it will be treated as absolute path:

<ul class="nav">
  <li><a href="{{ '/'|url }}">Index</a></li>
  <li><a href="{{ '/about'|url }}">About</a></li>
</ul>

Relative Linking

If you want to link relative to the current page, just leave out the slash:

<a href="{{ 'project-a'|url }}">Go To Project A</a>

If you want to link to a page in a different alternative you can use the optional alt parameter. For instance you can link to the current page in another alternative (. indicates the current page):

<a href="{{ '.'|url(alt='ru') }}">Русский</a>

Because the URL filter can also accept entire record objects you can easily link to all children of a page:

<ul class="nav">
{% for page in this.children %}
  <li><a href="{{ page|url }}">{{ page.title }}</a></li>
{% endfor %}
</ul>

asseturl Filter

A second filter that is available is the asseturl filter. It works similar to |url but can only link to assets from the assets/ folder. However unlike |url it will append a dummy query string with a hash of the source asset. This ensures that when the asset changes it will be newly cached.

Example:

<link rel="stylesheet" href="{{ '/static/styles.css'|asseturl }}">

The end result will look something like this:

<link rel="stylesheet" href="static/styles.css?h=deadbeef">
