Heroku Ruby On Rails服务器日志显示“用户"不存在 [英] Heroku Ruby On Rails Server Logs says 'Users' does not Exist

问题描述

我正在关注 Ruby On Rails图书教程，第2章，toy_app

存储库位于BitBucket上， https://bitbucket.org/Marium36/toy_app/

到目前为止，我可以在本地服务器上打开该应用程序，即

localhost:3000 

和

localhost:3000/users

heroku出现了问题.

Heroku应用只能打开

https://salty-wave-17330.herokuapp.com/

我尝试

https://salty-wave-17330.herokuapp.com/users

我收到错误消息

很抱歉，出了点问题.如果您是应用程序 所有者检查日志以获取更多信息.

服务器日志， https://bitbucket.org/Marium36/toy_app/src/master/heroku_server_logs

显示的持续错误消息是Users不存在---但确实存在，我可以在本地计算机中加载localhost:3000/users

请帮助！！！

解决方案

PG::UndefinedTable: ERROR表示您尚未创建表.您需要运行heroku run rake db:migrate，以便将表添加到您的Heroku Postgres.

I am following Ruby On Rails Book Tutorial, Chapter 2, toy_app

Repository is on BitBucket, https://bitbucket.org/Marium36/toy_app/

So far, I can open the app on my local server, i.e

localhost:3000 

and

localhost:3000/users

Problem arises with heroku.

Heroku app can only open

https://salty-wave-17330.herokuapp.com/

As soon as I attempt

https://salty-wave-17330.herokuapp.com/users

I get error,

We're sorry, but something went wrong. If you are the application owner check the logs for more information.

Server logs, https://bitbucket.org/Marium36/toy_app/src/master/heroku_server_logs

The continual error message that shows is that Users does not exist --- but it does, I can load in my local machine, i.e. localhost:3000/users

Please help!!!

解决方案

PG::UndefinedTable: ERROR means you haven't created the table. You need to run heroku run rake db:migrate so that the tables are added to your Heroku Postgres.
