路由錯誤呼喚「新」的方法與嵌套資源

Question

我有兩個嵌套的資源：

class Customer < ActiveRecord::Base 
    has_many :locations, :dependent => :destroy 
    accepts_nested_attributes_for :locations 
end 

class Location < ActiveRecord::Base 
    belongs_to :customer 
end 

在routes.rb中我有

resources :customers do 
    resources :locations 
end  

創建一個新的位置的代碼是

<%= link_to image_tag("add.png"), new_customer_location_path(@customer), :class => "button" %> 

當我嘗試創建新位置時，出現以下錯誤

路由錯誤

沒有路由匹配{：動作=> 「秀」，：控制器=> 「位置」，：CUSTOMER_ID =>＃：ID =>＃}

爲什麼：動作=>」顯示「被調用而不是」新「？

耙路輸出

customer_locations  GET /customers/:customer_id/locations(.:format)     {:action=>"index", :controller=>"locations"} 
         POST /customers/:customer_id/locations(.:format)     {:action=>"create", :controller=>"locations"} 
new_customer_location GET /customers/:customer_id/locations/new(.:format)    {:action=>"new", :controller=>"locations"} 
edit_customer_location GET /customers/:customer_id/locations/:id/edit(.:format)   {:action=>"edit", :controller=>"locations"} 
customer_location  GET /customers/:customer_id/locations/:id(.:format)    {:action=>"show", :controller=>"locations"} 
         PUT /customers/:customer_id/locations/:id(.:format)    {:action=>"update", :controller=>"locations"} 
         DELETE /customers/:customer_id/locations/:id(.:format)    {:action=>"destroy", :controller=>"locations"} 

在locations_controller.rb新動作控制器代碼

before_filter :find_customer 

def new 
    @location = @customer.locations.new 

    respond_to do |format| 
    format.html # new.html.erb 
    format.json { render json: @location } 
    end 
end 

我不明白的錯誤，我有正常工作，另外兩個嵌套資源，檢查了所有的代碼，看起來完全一樣... 「位置」是保留字還是有缺失/錯誤？

Answer 1

嘗試把一個右括號的IMAGE_TAG。

<%= link_to image_tag("add.png"), new_customer_location_path(@customer), :class => "button" %> 

Answer 2

好的，發現問題了。

內部應用程序/視圖/位置/ _form.html.erb 這是由應用程序/視圖/位置/ new.html.erb調用

有一個錯誤的道路幫手鍊接：

<%= link_to "Cancel", customer_location_path(@customer,@location) %> 

我已經把它改爲

​​

，現在一切正常
