Make will_paginate generate HTML that bootstrap.less will render nicely, fixed for will_paginate 3.0.2

  class BootstrapLinkRenderer < ::WillPaginate::ActionView::LinkRenderer
    protected

    def html_container(html)
      tag :div, tag(:ul, html), container_attributes
    end

    def page_number(page)
      tag :li, link(page, page, :rel => rel_value(page)), :class => ('active' if page == current_page)
    end

    def gap
      tag :li, link(super, '#'), :class => 'disabled'
    end

    def previous_or_next_page(page, text, classname)
      tag :li, link(text, page || '#'), :class => [classname[0..3], classname, ('disabled' unless page)].join(' ')
    end
  end

  def page_navigation_links(pages)
    will_paginate(pages, :class => 'pagination', :inner_window => 2, :outer_window => 0, :renderer => BootstrapLinkRenderer, :previous_label => '&larr;'.html_safe, :next_label => '&rarr;'.html_safe)
  end

Thank you so much for this!

@pplegend: Me too. This gist above is for will_paginate 3.0.2, not will_paginate 3.0.pre2. Check your gemfile. I'm still trying to find a solution for the old 'pre' version. Unfortunately, our app is entrenched it without a simple upgrade path.

I adjusted the css classes for bootstrap 3!

def html_container(html)
  tag :div, tag(:ul, html, :class => 'pagination')
end

def page_navigation_links(pages)
will_paginate(pages, :inner_window => 2, :outer_window => 0, :renderer => BootstrapLinkRenderer, :previous_label => '«'.html_safe, :next_label => '»'.html_safe)
end
