大家好，

我通过根据这个更改我的模型文件解决了我以前的新错误。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。我需要包括它吗？如果是这样，怎么做？

NoMethodError in ProductPhotosController#index

undefined method `key?' for nil:NilClass

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：

此问题发生在以 sqlite3 作为 db 的本地主机上。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 s3上的存储桶 choco_photos 中的文件夹“images”中。我还更改了 URL 和 PATH 以反映它，但我很确定我做错了什么。

PATH AND URL 文件是否反映了图像在 S3 上的存储和访问位置？

我会提到，即使在看了回形针上的 railscast 之后，我仍然对配置感到困惑。我查看了 AWS 推荐的文档，但没有帮助。具体来说，我对这种说法感到困惑：

# File 'lib/paperclip/storage/s3.rb', line 203

def s3_object style_name = default_style
  s3_bucket.objects[path(style_name).sub(%r{^/},'')]
end

任何和所有的帮助表示赞赏。

对于问题 1：Heroku 在 Cedar 堆栈上运行 1.9.2，您基于应用程序的 URL 运行该堆栈。我相信 1.9.1 只是一个目录，实际上与版本无关......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...

  1. 打开终端/控制台
  2. 导航到您的项目目录
  3. 类型：heroku 运行控制台（假设您已经安装了 heroku gem 或 CLI 工具）
  4. 控制台加载后，输入：RUBY_VERSION（您应该看到 1.9.2 或 1.9.3 输出）

对于问题 2：我必须更改 Gemfile 中的回形针。我使用它，它适用于雪松：

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

希望有帮助！
