Rails 3中沒有路由匹配（淺路由）

Question

這是我的routes.rb

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

resources :skills 

這是我的相關控制器（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 

這是相關的觀點：（/人次/subject/show.html.erb）

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

這是結果，當我運行耙路線

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

然而，當我試圖使我得到以下錯誤

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

什麼我做錯了的看法？

乾杯:-)

只是我想通了 - 我忘了@subject添加到的link_to方法。

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