Finding all parents of acts_as_tree relationship
I''m using acts_as_tree to maintain a hierarchy of categories (each
top-level category can contain multiple categories and each
sub-category can contain multiple sub-categories, etc.).
I want to be able to find all parents of a particular category. I
realize that I can use @category.parent or even
@category.parent.parent to move up in the hierarchy, but I need this
to happen dynamically
