LINK_TO从类中删除按钮：不能转换成字符串哈希

Question

我有这个简单的Ruby类（我用它从一个控制器内创建产品的集合）：

class ProductDashboardDecorator 
    include ApplicationHelper 
    include ActionView::Helpers::NumberHelper 
    include ActionView::Helpers::TagHelper 
    include ActionView::Helpers::AssetTagHelper 
    include ActionView::Helpers::UrlHelper 
    include ActionController::UrlWriter 

    def initialize(p) 
     @product = p 
    end 

    def special_links 
     ret = '' 
     # this works! 
     ret << content_tag(:a, 'X', :href => removee_product_path(@product), :title => 'rimuovi', :class => 'remove_link', :method => :delete) 

     # this don't! 
     ret << link_to('X', removee_product_path(@product), :title => 'rimuovi', :class => 'remove_link', :method => :delete) 

     return ret.html_safe 
    end 
end 

我想用link_to创建一个“删除”按钮。但是，当我这样做，我得到这个错误：

can't convert String into Hash 

这些路线：

map.resources :products, :member => { :removee => :delete }, :as => 'prodotti' do |product| 
    product.resources :watchers, :collection => { :add => :get } 
    end 

任何帮助吗？

尝试该语法中，未测试

content_tag(:span, link_to('X', removee_product_path(@product), :title => 'rimuovi', :class => 'remove_link', :method => :delete))
