Question

EDIT: I’ve altered the code to now read:

View code:

<h3>Your Orders:</h3>
<table class="order-items">
<th>Date</th>
<th>Order No.</th>
<th>View Order</th>
<% @orders.each do |order| %>
    <tr>
        <td><%= order.created_at.strftime("%d %b. %Y") %></td>
        <td><%= order.id %></td>
        <td><%= link_to 'Show',  order_path(order) %></td>
    </tr>
<% end %>   
</table>

<p><%= will_paginate @orders %></p>

Controller Code:

@customer = Customer.find(params[:id])
@orders = @customer.orders.paginate page: params[:page], order: 'id desc',
  per_page: 5

Routes:

resources :orders

resources :customers

get 'admin' => 'admin#index'

get 'account' => 'customers#show'

match '/account', :to => 'customers#show'

match'/signup', :to => 'customers#new'

controller :sessions do
  get  'login' => :new
  post 'login' => :create
  delete 'logout' => :destroy
end


resources :users

resources :line_items

resources :carts

get "store/index"

resources :products do
  get :who_bought, on: :member
end

resources :line_items do
  put 'decrease', on: :member
  put 'increase', on: :member
end

root to: 'store#index', as: 'store'

The problem is now that I’m getting the error:

The @orders variable appears to be empty. Did you forget to pass the collection object for will_paginate?

whenever I click on a “Show” link in the list of orders in the view. Tried restarting the server just in case, but can’t get it working :S!

Answer 1

It should be

<% @orders.each do |order| %>

not

<% @customer.orders.each do |order| %>
