Iterate over hashes in liquid templates

Question

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 tha         


        

Answer 1

  {% for link in page.links %}
      {% for item in link %}
        <a href="{{ item[0] }}">{{ link[1] }}</a>
      {% endfor %}
    {% endfor %}

I had a very similar issue, but I had multiple items in my variable so I used the undocumented item variable and it did the job.

Answer 2

I would define them like this in YAML:

links:
  demo: http://www.github.com/copperegg/mongo-scaling-demo

And then iterate:

{% for link in page.links %}
  <a href="{{ link[1] }}">{{ link[0] }}</a>
{% endfor %}

Answer 3

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 %}
