showing error when i customized will_paginate

i want the pagination to look like this "1 prev5<< prev< 6 next> next5>> 50"

1 means first page

50 means last page

6 means current page

so i customized the code somewhat like below in config/initializers/ PaginationListLinkRenderer (created new file to customize)

module WillPaginate

  class PaginationListLinkRenderer < LinkRenderer


 def to_html
       links = []

      links.unshift page_link_or_span(1, 'disabled first_page', 1)

  links.push  page_link_or_span(@collection.previous_page - 4, 'disabled prev5_page', @options[:previous])

  links.push  page_link_or_span(@collection.previous_page, 'disabled prev_page', @options[:previous_label])


   links.push page_link_or_span(@collection.current_page, 'current')

   links.push page_link_or_span(@collection.next_page, 'disabled next_page', @options[:next_label])

   links.push page_link_or_span(@collection.next_page + 4, 'disabled next5_page', @options[:next])

   links.push    page_link_or_span(@collection.total_pages,     'disabled last_page', @collection.total_pages)

  html = links.join(@options[:separator])



  html = html.html_safe if html.respond_to? :html_safe
  @options[:container] ? @template.content_tag(:div, html, html_attributes) : html
end

end 
end
