Iterate over hashes in liquid templates
I'm writing a site in Jekyll, which uses Liquid.
I have front matter for pages that I'd like to look like this:
---
title: Designing algorithms that scale horizontally
speaker: Luke Ehresman, CopperEgg
category: notes.mongodallas.talks
links:
- demo: http://www.github.com/copperegg/mongo-scaling-demo
layout: talknotes
---
In Liquid, the links section of YAML comes through as:
[{'demo' => 'http://www.github.com/copperegg/mongo-scaling-demo' }]
I'd like to be able to iterate over the array, doing something like this:
<a href="{{ link.value }}">{{ link.key }}</a>
But any ideas I've had so far have failed me.
Answer
When you iterate over a hash using a variable called hash, hash[0] contains the key and hash[1] contains the value on each iteration.
{% for link_hash in page.links %}
{% for link in link_hash %}
<a href="{{ link[1] }}">{{ link[0] }}</a>
{% endfor %}
{% endfor %}
