Hi,
I've tried looking for an answer to this via Google, various forums etc but have not found one yet - which seems surprising as I don't think the requirement is that unusual.
Is there an 'off the shelf' gem or rails plugin to create a grid or matrix based upon attributes of a model?
I've written a mechanism to suit my immediate needs but I'm wondering if there's a general purpose one available; or whether it's worth making my implementation more generic and releasing it for others to use.
Basically, what I'm looking to do is take a list of objects which have attributes 'name','A' and 'B' and produce a table with A across the top, B down the side and 'name' in cells where the object matches both A and B.
eg my object contains "name", "category" and "context" the range of values for each of "category" and "context" is fixed.
What I'd like is (and this looks OK in fixed width fonts)
