Ruhoh - Insert Tag every x items - ruby

Question

I'm new to Ruby and Ruhoh and have I am trying to do something like "Rails each loop insert tag every 6 items?" but I am using Ruhoh.
Basically, I have a list of posts and every 3 posts I want to create a new row div.
I have looked through all the Ruhoh documentation and there doesn't appear to be an easy way to do this. I think I need to create a plugin in Ruhoh for a collection, but having no experience in ruby I don't really understand what I am doing. Any help or guidance in the right direction would be great,
Cheers.

I'm fairly new to ruby myself, however I think this solution meets your needs!
Create a new file in the plugin directory called pages_collection_view_addons.rb (if it doesn't already exist).
Add this to that file:
module PagesCollectionViewAddons
def chunks(n = 3)
# Get all the pages
pages = all
chunks = []
# Split the 'pages' array into chunks of size n
pages.each_slice(n) { |slice|
chunks.push({pieces: slice})
}
chunks
end
end
# Inform Ruhoh of this new addon
Ruhoh::Resources::Pages::CollectionView.send(:include, PagesCollectionViewAddons)
In your template add something such as:
{{# posts.chunks}}
<div class="row">
{{# pieces }}
<h1>{{ title }}</h1>
{{/ pieces }}
</div>
{{/ posts.chunks }}
This will iterate over each of the chunks where each chunk looks like:
{pieces: [post1, post2, post3]}
Hope this helps.
