'heroku restart' 后坚持大礼包产品图片

Question

我有一个正在处理的示例页面：

http://os-oven.herokuapp.com/

我从哪里开始上传产品图片的。在我尝试的某个时刻，我不得不运行

heroku restart

这把我的照片擦掉了：

图片一定是保存在本地的，当我重新启动我的应用程序时，它从git中提取了最新的代码。

如何将大礼包的产品图片持久化到数据库中？

我的想法：

1. 将它们放在 s3 之类的东西中。不利的是我现在宁愿有一个 'free-er' 选项。另外，你会如何配置 spree 来做到这一点？
2. 获取版本控制中的文件。这可能有效，除非我需要 prod 和 dev 使用相同的数据库和存储在数据库中的相同文件路径。
3. 将 blob 保存到数据库。我知道这可能不是最有效的方法，但数据始终可用。仍然需要调整狂欢引擎才能做到这一点。

您无法在 heroku 上保存图片。 Heroku 有 "Read-only Filesystem" https://devcenter.heroku.com/articles/read-only-filesystem

您可以免费使用 cloudinary.com 或 Amazon S3 Amazon S3 还免费提供高达 5Gb 的空间。 http://aws.amazon.com/free/
