Question

当我尝试访问Heroku上最近发布的Rails应用程序时，它给出了以下错误：

Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

当我检查'heroku logs'时，我看到以下内容：

2013-02-15T18:56:06+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path=/ host=olivetalk.org fwd=76.168.74.9 dyno= queue= wait= connect= service= status=503 bytes=

我无法弄清楚可能出现的问题。有什么建议吗？

更新：以下是loggly插件的错误：

Answer 1

你添加了＆＃39; PG＆＃39; gem到您的Gemfile（或正确配置您的database.yml）？如果未正确设置数据库，Heroku应用程序将崩溃。

Heroku Rails App说“应用程序错误”
