This example is not my real app, but it's modeled pretty closely to it.

My mom schedules a couple hundred employees at a local warehouse. In their system, a worker can earn "points" for being late or missing shifts. Here we have a sort of summary screen for my mom, who may need to follow up with new employees or discipline employees with concerning levels of points.

Questions that arise as I code something like this:

• Which objects deserve presenters?

$('#products').append('<%= j render(@products) %>');
<% if @products.next_page %>
  $('.pagination').replaceWith('<%= j will_paginate(@products) %>');
<% else %>
  $('.pagination').remove();
<% end %>
