“没有路线匹配”的错误，但只有在新的

Question

我有一个窗体模型有一个嵌套的资源（一个图像上传与Carrierwave），并在嵌套的资源我有一个link_to，允许删除图像。点击链接将删除载波项目并删除图像。这一切都完全适用的编辑功能，而是试图去新的屏幕，我收到以下错误时：

No route matches {:controller=>"listings", :action=>"remove_image"} 
(ActionView::Template::Error) 

这里是有问题的链接：

<%= link_to "Delete this image", remove_image_path(builder.object.id), 
     :confirm => "Are you sure you want to delete this image?", 
     :method => :delete %> 

这里是我的路线进入：

match "/remove_image/:id" => "listings#remove_image", :as => "remove_image" 

下面是从ListingsController方法：

def remove_image 
    @image = SecondaryImage.find(params[:id]) 
    @listing = Listing.find(@image.listing_id) 
    @image.remove_image 
    @image.destroy 
    respond_to do |format| 
    format.html { redirect_to edit_listing_path(@listing), 
       notice: "Successfully deleted secondary image" } 
    end 
end 

UPDATE：耙路线 按照要求，在这里是如何简单地做这涉及到ListingsController

的路线？

<%= link_to "Delete this image", "/remove_image/#{builder.object.id}", 
    :confirm => "Are you sure you want to delete this image?", 
    :method => :delete %>
