Paginate over a collection (Array or Hash)
Sometimes could happen that we need to paginate something different from a collection, I found this very useful method that acts similar to a paginate but it works for Arrays ( and Hashes )
def paginate_collection(collection, options = {}) default_options = {:per_page => 10, :page => 1} options = default_options.merge options pages = Paginator.new self, collection.size, options[:per_page], options[:page] first = pages.current.offset last = [first + options[:per_page], collection.size].min slice = collection[first...last] return [pages, slice] end
