也许有人知道为什么这样：
也许有人知道为什么这样：
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
像这样的例外：
No route matches {:controller=>"devise/trademarks"}

以及如何使它工作？
解决方法
您必须在路径中添加斜杠.
例如：
例如：
<li><%= link_to "Events",:controller => "/events",:action => "index" %></li>
