Ruby on Rails爲第三個模型形成路徑

Question

我正在爲我的建築物中的網絡製作地圖。我有單獨的樓層模型工作，當你點擊顯示方法時列出每個開關。然後，我想擁有它，以便您可以單擊每個交換機以查看每個交換機端口上的插孔編號。由於我提出了另一個問題，我對交換機的工作有了一些看法，但現在我仍然試圖在同一節目中顯示插孔。下面是我部分的接口（應用程序/視圖/插孔/ _jacks.html.erb）：

<%= form_for <WhatDoIPutHere?> do |f| %> 
    <div class="field"> 
    <%= f.label :number %><br /> 
    <%= f.text_field :number %> 
    </div> 
    <div class="actions"> 
    <%= f.submit %> 
    </div> 
<% end %> 

現在我知道我需要運行一個耙途徑找出路。 這裏是我耙路線的結果是：

floor_switch_jacks GET /floors/:floor_id/switches/:switch_id/jacks(.:format)   jacks#index 
        POST /floors/:floor_id/switches/:switch_id/jacks(.:format)   jacks#create 
new_floor_switch_jack GET /floors/:floor_id/switches/:switch_id/jacks/new(.:format)  jacks#new 
edit_floor_switch_jack GET /floors/:floor_id/switches/:switch_id/jacks/:id/edit(.:format) jacks#edit 
floor_switch_jack GET /floors/:floor_id/switches/:switch_id/jacks/:id(.:format)  jacks#show 
        PUT /floors/:floor_id/switches/:switch_id/jacks/:id(.:format)  jacks#update 
        DELETE /floors/:floor_id/switches/:switch_id/jacks/:id(.:format)  jacks#destroy 
    floor_switches GET /floors/:floor_id/switches(.:format)       switches#index 
        POST /floors/:floor_id/switches(.:format)       switches#create 
    new_floor_switch GET /floors/:floor_id/switches/new(.:format)      switches#new 
edit_floor_switch GET /floors/:floor_id/switches/:id/edit(.:format)     switches#edit 
     floor_switch GET /floors/:floor_id/switches/:id(.:format)      switches#show 
        PUT /floors/:floor_id/switches/:id(.:format)      switches#update 
        DELETE /floors/:floor_id/switches/:id(.:format)      switches#destroy 
      floors GET /floors(.:format)            floors#index 
        POST /floors(.:format)            floors#create 
     new_floor GET /floors/new(.:format)           floors#new 
     edit_floor GET /floors/:id/edit(.:format)          floors#edit 
      floor GET /floors/:id(.:format)           floors#show 
        PUT /floors/:id(.:format)           floors#update 
        DELETE /floors/:id(.:format)           floors#destroy 
     home_index GET /home/index(.:format)           home#index 
       root  /               home#index 

我的問題是我怎麼讀耙路線以查找的form_for行的正確語法？我有同樣的問題讓我的開關視圖在第一時間工作。如果這是一個簡單的問題，並有一個指導，那麼請隨時發送給我。我似乎無法找到一個具體到這個。

在此先感謝您的幫助！

編輯：

class JacksController < ApplicationController 

    def create 
    @switch = Switch.find(params[:switch_id]) 
    @jack = @switch.jacks.create(params[:jack]) 
    redirect_to switch_path(@switch) 
    end 

    def destroy 
    @switch = Switch.find(params[:switch_id]) 
    @jack = @switch.jacks.find(params[:id]) 
    @jack.destroy 
    redirect_to switch_path(@switch) 
    end 

end

您可以嵌套形式爲您嵌套模型。

form_for @floor do |f| 
    f.fields_for :switches do |g| 
    g.fields_for :jacks do |h| 
     h.label :number 
    end 
    end 
end
