的Rails 3 - 建立一個表單更新記錄

Question

我有以下兩種模式：

class PhotoAlbum < ActiveRecord::Base 
    belongs_to :project 
    has_many :photos, :dependent => :destroy 

class Photo < ActiveRecord::Base 
    belongs_to :photo_album 

當用戶查看照片，網址就像是如下：「/ photo_albums/40 /照片頁？ = 6"

在這張照片視圖頁面（專輯裏）我想給用戶更新圖像的選項，所以我使用了以下內容：

<% form_for [:photo, @photos.first], :url => photo_album_photos_path, :html => { :multipart => true } do |f| %> 


<form method="post" id="edit_photo_124" enctype="multipart/form-data" class="edit_photo" action="/photo_albums/40/photos" accept-charset="UTF-8"> 

我認爲這是正確的？問題是，當我點擊更新，我得到以下錯誤：

No route matches "/photo_albums/40/photos" 

這裏是我的路線，這看起來不錯，不是嗎？

photo_album_photo PUT /photo_albums/:photo_album_id/photos/:id(.:format)  {:action=>"update", :controller=>"photos"} 
photo PUT /photos/:id(.:format)         {:action=>"update", :controller=>"photos"} 

想法？感謝

UPDATEW¯¯配置路由文件：

resources :photos do 
    resources :comments, :only => [:create, :update,:destroy], :constraint => {:context_type => "photos"} 
    collection do 
       post 'upload' 
     get 'search' 
    end 
end 


    resources :photo_albums do 
     resources :comments, :only => [:create, :update,:destroy], :constraint => {:context_type => "photo_albums"} 
     resources :photos 
     collection do 
      get 'search' 
     end 
    end 

Answer 1

嘗試表單更改爲類似：

<% form_for [@photo_album, @photos.first], :html => { :multipart => true } do |f| %> 

其中@photo_album是你photo_album對象，或

<% form_for @photos.first, :url => photo_album_photo_path(@photo_album, @photo), :html => { :multipart => true } do |f| %> 

這基本上是一樣的。有這方面的工作，你應該在你的route.rb如下：

resources :photo_albums do 
    resources :photos 
end
