使用 Heroku、Rails 时出现 Heroku 500 错误 [关闭]

我正在尝试使用回形针将图像上传到 S3。目前它在开发中运行得很好，但是当我将它推送到 heroku 时，我得到的状态是 500。

我查看了当前的主题，其中的一些原因是缺少 pg gem 和未配置存储桶名称，但我已经检查了这些。

我的错误日志目前是这样说的

我唯一的提示是 status=500。

非常感谢任何想法/帮助！

ENV Vars http://en.wikipedia.org/wiki/Environment_variable

最相关的问题可能是你没有得到你的ENV变量设置正确。这些都是环境具体 - 这意味着您必须在部署应用程序的每个“环境”（服务器）中设置它们

许多人面临的一个常见问题是，他们会在不设置这些 ENV 变量的情况下部署到 Heroku，从而阻止系统访问其所需的信息。

解决方案是使用heroku config:set VARIABLE=value在你的命令中 https://devcenter.heroku.com/articles/config-vars

--

生产

您的日志没有任何错误，这不是很有帮助

因此，另一种猜测是您没有设置production环境选项 https://devcenter.heroku.com/articles/paperclip-s3在 Rails 本身中：

#config/environments/production.rb
config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
  }
}

还有一个问题你may有，就是这样paperclip使用bucket选项。我们发现需要这样的设置才能正常工作：

#config/environments/production.rb
config.paperclip.defaults = {
    storage: :s3,
    s3_host_name: 's3-eu-west-1.amazonaws.com',
    s3_credentials: {
      access_key_id: ENV['AWS_ACCESS_KEY_ID'],
      secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
    },
    bucket: ENV['S3_BUCKET_NAME']
}
