[英]Rails - will_paginate gem not working when using .each do
EDIT: I've altered the code to now read: 编辑:我已更改代码以读取:
View code: 查看代码:
<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: 控制器代码:
@customer = Customer.find(params[:id])
@orders = @customer.orders.paginate page: params[:page], order: 'id desc',
per_page: 5
Routes: 路线:
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: 现在的问题是我遇到了错误:
The @orders variable appears to be empty. @orders变量似乎为空。 Did you forget to pass the collection object for will_paginate?
您是否忘记为will_paginate传递收集对象?
whenever I click on a "Show" link in the list of orders in the view. 每当我单击视图中的订单列表中的“显示”链接时。 Tried restarting the server just in case, but can't get it working :S!
尝试重新启动服务器以防万一,但无法使其工作:S!
It should be 它应该是
<% @orders.each do |order| %>
not 不
<% @customer.orders.each do |order| %>
Pls check this code 请检查此代码
@customer = Customer.find(params[:id])
@orders = @customer.orders.paginate page: params[:page], order: 'title',per_page: 5
in view 鉴于
<% @orders.each do |order| %>
