Devise＆Heroku错误

Question

我试图在Heroku上进行设计工作。它可以在我的电脑上正常工作，但是当我在Heroku上推送我的代码时，每次尝试创建用户时都会收到此错误：“我们很抱歉，但出错了。

如果您是应用程序所有者，请查看日志以获取更多信息。我检查了日志并没有错误。在这里，他们是：

任何的猜测？当您创建用户

Answer 1

DB

Any guess? 

我想象的错误是你没有迁移在Heroku数据库。

这是一个常见的问题，假设你的开发环境是“只是”你的Rails应用程序 - 它不止于此。你必须确保你的生产数据库填充了你在你的Rails数据库具有相同的数据，也

我会确保你已经做到了这一点：

$ Heroku的运行耙分贝：迁移

-

调试

手法高明的伎俩，以 “调试”在Heroku上实际上是让你的应用以“开发”模式运行。虽然你必须确保您切换回在生产模式下运行之后，如果你做到以下几点，它会告诉你是什么错误正确：

#config/environments/production.rb 
config.consider_all_requests_local = true # false 

改变这一状况，重新推到Heroku的&然后您将能够在屏幕上看到详细的错误版本。我认为它会说你没有在你的数据库中的正确的列;）

Answer 2

此行日志

2014-09-13T06:28:34.201030+00:00 heroku[router]: at=info method=POST path="/users" host=birdl-dev.herokuapp.com request_id=c1e7ab4c-68dd-433e-8f26-870c2392ab3e fwd="24.50.121.235" dyno=web.1 connect=1ms service=772ms status=500 bytes=1335 

在告诉你，一个异常情况发生。尝试在production.rb

config.log_level = :debug 

设置并重新启动服务器来查看日志中的异常回溯。

Answer 3

另外，不要忘了设置config.action_mailer.default_url_options在config/environments/production.rb并建立一个邮件程序。或者，如果您尚未准备好设置邮件程序，请设置config.action_mailer.perform_deliveries = false。
