I've a normal Category model implemented with acts_as_tree (name,
parent_id) that has_many :products (name, category_id).
What I'm asking for is a method to fetch every product that belongs
fall into a particular category and its children, eg: if I'm asking
for a root node (/category/show/1) I need to display every product
that have category_id = 1 AND every product of the children
After that I must paginate results, search, but that's really another
Somebody got an advice how to accomplish this?
