EDIT2〜
大家好，
我根据this更改了我的模型文件，解决了以前的新错误。我不知道为什么，但它解决了它。我现在有这个错误要处理。 ：|
没有钥匙？我的控制器中的方法。我需要包含它吗？如果是这样，怎么样？

这是我的控制器：
1 class ProductPhotosController < ApplicationController
2 # GET /product_photos
3 # GET /product_photos.json
4 def index
5 @product_photos = ProductPhoto.all
6
7 respond_to do |format|
8 format.html # index.html.erb
9 format.json { render json: @product_photos }
10 end
11 end
这是我的模特：
1 class ProductPhoto < ActiveRecord::Base
2 has_attached_file :image,
3 :style => {:small => "150x150"},
4 :storage => :s3,
5 :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
6 :path => "chocosite/:attachment/:style/:id.:extension"
7 end

Heroku加载错误 - 回形针
问题是我在模型中发现的语法错误。我现在有一个新问题
我做了什么：
此问题发生在本地主机上，sqlite3为db。我登录到s3模块并将曾经在'public / system / images / 000/000 /'中的所有相关文件夹上传到文件夹'images' s3上的桶choco_photos。我也改变了URL和PATH以反映它，但我很确定我做错了什么。
PATH和URL文件是否反映了在S3上存储和访问图像的位置？
我会提到即使看完回形针上的railscast，我仍然对配置感到困惑。我查看了AWS推荐的文档，但it没有帮助。具体而言，我对此声明感到困惑：
# File 'lib/paperclip/storage/s3.rb', line 203
def s3_object style_name = default_style
s3_bucket.objects[path(style_name).sub(%r{^/},'')]
end
感谢任何和所有帮助。

这是我的gemfile：
12 group :production do
13 gem 'pg'
14 end

16 gem 'bootstrap-sass', '2.0.0'
17 gem 'paperclip', '~> 3.0'
18 gem 'aws-sdk', '~> 1.3.4'
编辑结束
答案 0 :(得分：0)
对于问题1：Heroku在Cedar堆栈上运行1.9.2，根据您应用的URL，您可以使用它。我相信1.9.1只是一个目录，并没有真正与版本相关...我在文件夹名称中的1.9.1和我的系统实际运行1.9.2或1.9.3之间得到了相同的“不匹配”（和我只通过RVM运行1.9.2或1.9.3）。
您可以通过在heroku上打开Rails控制台来验证Heroku版本。
对于问题2：我必须改变我在Gemfile中使用回形针的方式。我使用它，它适用于Cedar：
gem 'paperclip', "~> 3.0"
gem "aws-sdk"
在我的相关模型中：
has_attached_file :photo,
:storage => :s3,
:s3_credentials => "#{Rails.root}/config/s3.yml",
:styles => {
:large => "600x480",
:medium => "330x230",
:small => "210x150",
:thumb => "90x90"
},
:path => 'images/products/:style/:filename'
在我的s3.yml文件中：
development:
access_key_id: MYKEY
secret_access_key: MYSUPERSECRETACCESSKEY
bucket: bucketname
希望有所帮助！
