Middleman - Unique Categories with amount of posts in each sorted

Question

I want to get the Unique categories from my blog posts - but also return the count of how many posts are in each category

Currently I have this

= blog( 'portfolio' ).articles.map { | r | r.data.category }.uniq.sort

I guess I need to remove the Uniq and Sort and do some Group.by then sort.

Any help appreciated to get this one liner sorted and fast

Cheers

Ian

This Stack Overflow question should answer your question too. It shows a number of ways that you could get a Hash mapping from category to count.
