Liquid templates - accessing members by name
- by egarcia
I'm using Jekyll to create a new blog. It uses Liquid underneath.
Jekyll defines certain "variables": site, content, page, post and paginator. These "variables" have several "members". For instance, post.date will return the date of a post, while post.url will return its url.
My question is: can I access a variable's member using another variable as the member name?
See the following example:
{% if my_condition %}
{% assign name = 'date' %}
{% else %}
{% assign name = 'url' %}
{% endif %}
I have a variable called name which is either 'date' or 'url'.
How can I make the liquid equivalent of post[name] in ruby?
The only way I've found is using a for loop to iterate over all the pairs (key-value) of post. Beware! It is quite horrible:
{% for property in post %}
{% if property[0] == name %}
{{ property[1] }}
{% endif %}
{% endfor %}
Argh! I hope there is a better way.
Thanks.
