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.
