我在将我的Rails应用程序部署到Heroku时遇到问题,在尝试访问应用程序时会抛出此错误:

PGError:错误:关系"组织"不存在(ActiveRecord :: StatementInvalid)

SELECT a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull
FROM pg_attribute a LEFT JOIN pg_attrdef d
  ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"organizations"'::regclass
  AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum

有人有什么想法吗？这对我来说是第一次,特别是因为我已经在其他应用程序上使用Heroku一年了,并且没有看到这样的东西.当然,一切都适用于本地SQLite.

在生产(Heroku)中,我收到以下错误:

我正在使用CarrierWave在Rails 3.1中上传文件,我正在寻找一种节省服务器空间的方法.许多上传的照片都超过了20MB,所以在将它们处理成1024 x 1024后,我想删除原始照片.在上传器类中有没有简单的方法呢？

谢谢, - 马克
