Add in the kaminari gem

Restart the server.

Load in a few orders

edit script/load_orders.rb
Order.transaction do
  (1..100).each do |i|
    Order.create(name: "Customer #{i}", address: "#{i} Main Street",
      email: "customer-#{i}@example.com", pay_type: "Check")
  end
end
rails runner script/load_orders.rb

Modify the controller to do pagination

edit app/controllers/orders_controller.rb
  def index
    @orders = Order.order('created_at desc').page(params[:page])
  end

Add some navigational aids

edit app/views/orders/index.html.erb
<p id="notice"><%= notice %></p>
 
<h1>Orders</h1>
 
<table>
  <thead>
    <tr>
      <th>Name</th>
      <th>Address</th>
      <th>Email</th>
      <th>Pay type</th>
      <th colspan="3"></th>
    </tr>
  </thead>
 
  <tbody>
    <% @orders.each do |order| %>
      <tr>
        <td><%= order.name %></td>
        <td><%= order.address %></td>
        <td><%= order.email %></td>
        <td><%= order.pay_type %></td>
        <td><%= link_to 'Show', order %></td>
        <td><%= link_to 'Edit', edit_order_path(order) %></td>
        <td><%= link_to 'Destroy', order, method: :delete,
              data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>
  </tbody>
</table>
