問題:我試圖通過回形針上傳圖片到Amazon S3服務器,它不會通過驗證。具體來說,我得到的消息是:

驗證失敗:照片的文件名必須設置

如果有人可以幫告訴我,我已經錯了,它會非常感激。

這是我的一些源代碼。
型號:

Class Transaction < ActiveRecord::Base 

attr_accessible :amount, :user_id, :group_id, :photo 

belongs_to :users 
belongs_to :groups 

has_attached_file :photo, 
    :styles => { 
    :thumb=> "100x100#", 
    :small => "200x200>", 
    :large => "600x400>" }, 
:storage => :s3, 
:s3_credentials => "#{Rails.root.to_s}/config/s3.yml", 
:path => "/:attachment/:id/:style.:extension" 

validates_attachment_presence :photo 
validates_attachment_size :photo, :less_than => 5.megabytes 
validates_attachment_content_type :photo, :content_type => ['image/jpeg', 'image/png', 'image/jpg'] 
end 

控制器:

class TransactionsController < ApplicationController 

def confirm 
end 

def create 
@transaction = Transaction.new(params[:transaction]) 
if @transaction.save! 
    render 'confirm' 
else 
    redirect_to :back 
end 

end 

檢視:

<%= form_for(@transaction, :url => transactions_path, :html => { :mulitpart => true }, :validate => true) do |t| %> 
<%= t.hidden_field :user_id, :value => current_user.id %> 
<%= t.label "Select Group:" %> 
<%= t.select :group_id, options_from_collection_for_select(@groups, :id, :name), :class => "ui-corner-all" %><br /> 
<%= t.label "Amount:" %> 
$ <%= t.text_field :amount, :size => 20 %> <br /> 
<%= t.label "Receipt:" %> 
<%= t.file_field :photo, :size => 20 %> <br /> 
<%= t.submit 'Continue', :name => "withdrawal" %> 
<% end %> 

配置/ s3.yml:

development: 
bucket: trans-dev 
access_key_id: MY_ID 
secret_access_key: MY_KEY 
test: 
bucket: trans-test 
access_key_id: MY_ID 
secret_access_key: MY_KEY 
production: 
bucket: trans-pro 
access_key_id: MY_ID 
secret_access_key: MY_KEY 

schema.rb:

create_table "transactions", :force => true do |t| 
t.integer "amount",    :default => 0,  :null => false 
t.integer "user_id",        :null => false 
t.integer "group_id",        :null => false 
t.datetime "created_at" 
t.datetime "updated_at" 
t.string "photo_file_name" 
t.string "photo_content_type" 
t.integer "photo_file_size" 
t.datetime "photo_updated_at" 
end 

我知道,當我說:

@ transaction.save!

它會向瀏覽器發出錯誤信息。如果我不這樣做,那麼它不會保存,我會被重定向回窗體。我已經閱讀了很多教程,之前我已經做了這些,所以我很困惑它爲什麼不起作用。我嘗試將它上傳到Heroku,看看它是否能在那裏工作,但它也失敗了。

謝謝,任何意見表示讚賞。

編輯:這是我從我的服務器得到的消息。

我想你是因爲你使用的是已經在使用Rails的替代Rails.root,看看你是否面臨同樣的問題被棄用3.儘量RAILS_ROOT面臨這樣的問題。在更正之前,請檢查Rails.root的正確用法。
