I need to flip the direction, so that the next button takes you to the next newest and the previous takes you to the previous oldest page.

pagnation flip!

<% (page_number - num_pages .. page_number + num_pages).select{|i| i > 0 && i <= num_pages}.each do |i| %>
    <% if i == page_number %>

      <li>
        <span class="active">
          <%= i %>
        </span>
      </li>

    <% else %>

      <li>
        <% page = nil %>
        <% (i .. page_number).each do page = page ? page.metadata[:locals]['prev_page'] : prev_page; end %>
        <% (page_number ... i).each do page = page ? page.metadata[:locals]['next_page'] : next_page; end %>
        <%= link_to "#{i}", page && page.url %>
      </li>

    <% end %>
  <% end %>

  <% if paginate %>
    <% if next_page %>

      <li><%= link_to 'Next page <i class="fa fa-angle-right"></i>', next_page %></li>

    <% else %>
      
    <li>
      <span class="disabled">Last Page <i class="fa fa-angle-right"></i></span>
    </li>

    <% end %>
  <% end %>
