ruby-on-rails-3 - Rails 3没有路由匹配（浅路由）

Question

这是我的路线.rb

resources :subjects, :shallow => true do
   resources :skills, :only => [:new, :create]
end

resources :skills

这是我的相关控制器（SkillsController）

def new
# if action is called by new_subject_skill_path then
# subject_id is not nil
   if params[:subject_id]
     @subject = Subject.find(params[:subject_id])
   end
   @skill = Skill.new
end

这是相关的观点：（/views/subject/show.html.erb）

<%= link_to 'Add new skill', new_subject_skill_path %>

这是我运行rake 路线时的结果

new_subject_skill GET  /subjects/:subject_id/skills/new(.:format) skills#new

然而，当我尝试渲染视图时，出现以下错误

No route matches {:action=>"new", :controller=>"skills"}

我究竟做错了什么？

干杯:-)

我刚刚想通了 - 我忘记将 @subject 添加到 link_to 方法。

<%= link_to 'Add new skill', new_subject_skill_path(@subject) %>
