module WillPaginate
  module ActionView
    def will_paginate(collection = nil, options = {})
      options[:renderer] ||= BootstrapLinkRenderer
      super.try :html_safe
    end

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

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

    end
  end
end

this is amazing. thanks.

For reference, I had to add a require line, but only the action_view require mentioned by @grosser was necessary.

This gist worked a treat for me, although it did also need the two require modules pointed out by @grosser. Thanks you.

Just use: tag :ul, html, container_attributes instead of tag :div, tag(:ul, html), container_attributes
and it will work just fine with Bootstrap 3. They removed the div (http://getbootstrap.com/components/#pagination).

Thank you @grosser

thanks @grosser but why I needed to add it while it was working on development and I was getting error only on production.

don't remember what was going on here 🤷‍♂️

It was better for me to add this gem https://github.com/delef/will_paginate-bootstrap4 and solves the issue
