link_to（：controller =>「something」）helper +設計無法正常工作

Question

all！ 也許有人知道爲什麼這樣的：

def index_link(object, content = t("#{object.to_s.pluralize}.index")) 
    #link_to(content, {:controller=>object.to_s.pluralize}, :scope=>"") if can?(:read, p(object)) #this doesn't work too 
    link_to(content, :controller=>"trademarks") 
    #link_to(content, trademarks_path) #this do work, but I need to set path from object 
end 

使得這樣一個例外：

No route matches {:controller=>"devise/trademarks"} 

堆棧：

，以及如何使其工作？

Answer 1

您必須向路徑添加斜槓。 例如：

<li><%= link_to "Events" , :controller => "/events", :action => "index" %></li>

這裏是耙路線的一部分：

      user_session POST /users/login(.:format)   {:controller=>"devise/sessions", :action=>"create"}

     user_password POST /users/password(.:format)  {:controller=>"devise/passwords", :action=>"create"} 
    new_user_password GET /users/password/new(.:format) {:controller=>"devise/passwords", :action=>"new"} 
    edit_user_password GET /users/password/edit(.:format) {:controller=>"devise/passwords", :action=>"edit"} 
         PUT /users/password(.:format)  {:controller=>"devise/passwords", :action=>"update"}

         PUT /content/:id(.:format)   {:controller=>"contents", :action=>"update"} 
         DELETE /content/:id(.:format)   {:controller=>"contents", :action=>"destroy"}

         PUT /trademarks/:id(.:format)  {:controller=>"trademarks", :action=>"update"} 
         DELETE /trademarks/:id(.:format)  {:controller=>"trademarks", :action=>"destroy"}
