will_paginate在相同的實例變量，但爲三個不同的顯示屏

Question

這是控制器我有訂單的寫入器。

def index 
    if current_user.has_role? :admin 
     @orders = Order.all.paginate(:page => params[:page], :per_page => 5) 
    elsif current_user.has_role? :customer 
     @orders = Order.where(:email => current_user.email).paginate(:page => params[:page], :per_page => 5) 
    elsif current_user.has_role? :white_label 
     @orders = Order.where(:performer_id => (Performer.where(:white_label_id => current_user.white_label.id))).paginate(:page => params[:page], :per_page => 5) 
    else 
     @orders = current_user.performer.orders.paginate(:page => params[:page], :per_page => 5) 
    end 
    @custom_video = CustomVideo.new 
    end 

如你所見，我用will_paginate寶石來做分頁。這是我正在做分頁的瀏覽頁面。

<div class="container"> 
    <div class="span 8"> 
      <% if current_user.has_role? :admin %> 
      <%role =1%> 
      <%elsif current_user.has_role? :performer %> 
      <%role =2%> 
      <% else %> 
      <%role =3%>   
      <% end %>

問題是這樣的。如果我點擊第一張桌子的第二頁，那麼它也是第二張桌子。我試着給：param_name =>'questions_page'建議here。但是這裏的麻煩是，我沒有爲表格使用不同的實例變量，而是使用同一個變量。我如何解決這個問題？>

你幾乎已經回答了你自己的問題。如果您希望它們單獨運行，則需要爲每個表使用單獨的實例變量。
