这是我为Orders写的控制器。
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
如您所见，我使用will_paginate gem进行分页。这是我正在进行分页的视图页面。
<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 %>

问题在于此。如果我单击第一个表的第二页，它也将转到下一个表的第二页。我试过给出：param_name =＆gt; 'questions_page'建议here。但问题是，我没有为表使用不同的实例变量，而是使用相同的实例变量。我该如何解决这个问题？＆gt;
答案 0 :(得分：0)
你几乎回答了自己的问题。如果希望它们单独运行，则需要为每个表使用单独的实例变量。
