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
