带有S3的回形针 - 未定义的方法

我正在尝试在我的Rails 3.2应用程序中使用Paperclip gem和Amazon S3。但是,当我添加时出现问题:storage => :s3和S3信息以及生成表单。

错误:

undefined method `photo' for #<PlacePhoto:0x007fdbbd1e75a8>

提取的来源(第78行):

75:   <% end %>
76: 
77:   <%= f.simple_fields_for :place_photos do |photo| %>
78:     <%= photo.input :photo %>
79:     <%= photo.input :description,
80:       :label => "Photo label",
81:       :input_html => { :class => 'span4', :rows => 2 } %>

型号:

class PlacePhoto < ActiveRecord::Base
  has_attached_file :photo, 
    :styles => { :medium => "300x300#", :thumb => "100x100#" },
    :storage => :s3,
    :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
    :path => "/:style/:id/:filename"
  attr_accessible :description, :photo

  belongs_to :place

  validates_attachment :photo,
    :presence => true,
    :content_type => { :content_type => /image/ },
    :size => { :in => 0..2.megabytes }
end

移植

class CreatePlacePhotos < ActiveRecord::Migration
  def change
    create_table :place_photos do |t|
      t.text :description
      t.integer :place_id
      t.has_attached_file :photo

      t.timestamps
    end
  end
end

我使用下面的文章来实现S3:http://doganberktas.com/2010/09/14/amazon-s3-and-paperclip-rails-3/。我做了捆绑安装,rake db:migrate并重启服务器。

有趣的是,当模型缺少S3信息时,错误不会出现并且正在生成表单:

型号(其他版本):

class PlacePhoto < ActiveRecord::Base
  has_attached_file :photo, 
    :styles => { :medium => "300x300#", :thumb => "100x100#" }
  attr_accessible :description, :photo

  belongs_to :place

  validates_attachment :photo,
    :presence => true,
    :content_type => { :content_type => /image/ },
    :size => { :in => 0..2.megabytes }
end

通过改变解决问题:

:s3_credentials => "#{RAILS_ROOT}/config/s3.yml",

:s3_credentials => "#{Rails.root}/config/s3.yml",
