Ruby on Rails：link_to表现得很奇怪

Question

所以......这是我的link_to

＆lt;％= link_to“Archive”，：action =＆gt; 'archive'％＆gt;

和我在控制台中的输出

 Parameters: {"action"=>"archive", "controller"=>"achievables"}

为什么动作不“归档”？ 该方法在控制器中定义...拼写正确且一切。

编辑： 来自routes.rb

  map.archives 'achievable/archive', :controller => 'achievables', :action => 'archive'

  map.resources :achievables, :member => {:build => [:get,:post], :publish_detail => [:get,:post], :publish=>[:get,:post], :confirm_publish=>[:get,:post], :confirm_delete=>[:get,:post]}

现在，错误是

Showing app/views/layouts/build_archivable.html.erb where line #6 raised:

Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id

这又是错误的道路。 = \

尝试将操作指定为字符串而不是符号：

<%= link_to 'Archive', :action => 'archive' %>

或者，您可能在config/routes.rb内定义了更高优先级的路由，该路由在默认/:controller/:action/:id路由之前匹配（Rails从文件顶部开始并向下工作，直到达到路径为止匹配网址。
