Hi all,
The subject sums up what I want to do in a nutshell. I have a collection
of ActiveRecord objects (@galleries), and I want to generate from it
another collection of arrays, each three elements long. This is simply
so I can display preview pictures from all my @galleries in a three
column table.
What I want to end up with is something like this that I can iterate
over to build my table:
@collected -> [[gallery1, gallery2, gallery3],
[gallery4, gallery5, gallery6]]
etc
I cannot for the life of me figure out a clean way to do it. Any
hints or prods in the right direction would be great ;-)
Many thanks,
Dan

That looks just the thing! Thanks (to Greg, too) for the pointer. I should have known Rails could do it for me!
