Question

index.html.erb

<%= form_tag(:controller => 'publishers', :action => 'playlist' ) do  %>
<table id='audio_list' >

  <thead>
     <tr>
      <th></th> 
       <th>Nr </th>
       <th>Title</th>

       <th></th>    
      </tr>
  </thead>
<tbody>

<% @publishers.each do |publisher| %>
<tr>
   Here is my check_box_tag am sending to the controller
    <td><%= check_box_tag  "publisher_ids[]", publisher.id  %></td>
      <td><%=  publisher.id  %></td>
    <td><%=  publisher.title  %></td>  
    <%= link_to 'Play',  publisher ,:remote => true  %>  
    </td>      

 </tr> 
  <% end %>
  </tbody>
</table>    
<br/>
<br/>
<%= submit_tag "Create Playlist" %>
<% end %>

控制器

def playlist
@test_list=Publisher.order('id DESC').find(params[:publisher_ids])
end

现在控制器只从一个页面获取检查值，我想从所有页面获取检查值。

.find()返回一个项目，其输入（如果是微不足道的话）被解释为该模型的ID。试试.find_all_by_publisher_id()

如何从所有页面检索选定的check_box_tag值？实际上在控制器中，我只从一页获得
