Howto paginate an Array

Posted by Sandro Paganotti in Ruby on Rails - comments are closed

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

I really don’t know who is the author, so please if you are the author post a comment.
