Question

I have a list of items, those items have some attributes one of which is an array list. The array list may be empty or not.

How do i retrieve the items from the list that their array list is not empty

Answer 1

You can use select together with present? (or reject/blank?):

items = items.select{|x| x.array_attribute.present?}
