## Constuct an array of hashes that will allow the user, using Liquid, to
|
||
|
|
## iterate through the keys of _kv_hash_ and be able to iterate through the
|
||
|
|
## elements under each key.
|
||
|
|
##
|
||
|
|
## Example:
|
||
|
|
## categories = { 'Ruby' => [<Post>, <Post>] }
|
||
|
|
## make_iterable(categories, :index => 'name', :items => 'posts')
|
||
|
|
## Will allow the user to iterate through all categories and then iterate
|
||
|
|
## though each post in the current category like so:
|
||
|
|
## {% for category in site.categories %}
|
||
|
|
## h1. {{ category.name }}
|
||
|
|
## <ul>
|
||
|
|
## {% for post in category.posts %}
|
||
|
|
## <li>{{ post.title }}</li>
|
||
|
|
## {% endfor %}
|
||
|
|
## </ul>
|
||
|
|
## {% endfor %}
|
||
|
|
##
|
||
|
|
## Returns [ {<index> => <kv_hash_key>, <items> => kv_hash[<kv_hash_key>]}, ... ]
