Let's say I have a Recipe model, and it is a parent of the Review
model. Reviews are entered by users of the system, with one or more
tags using the acts_as_taggable_on_steroids plugin (for instance).
What I'm interested in is how to show *all* tags for a particular
Recipe - meaning all tags applied to every child Review of that
For an example of what I'm talking about, look at this page from this
They are showing the most popular tags from all Reviews on a
particular Beer. I'm trying to figure out how to do that.
But I have no idea where to start, since the tagging is such a wily
concept to me. Any suggestions?
