Question

好的，所以我将一个非常基本的应用程序部署到Heroku。我跟着tutorial写了这封信。关于这次部署的一切都是教科书，但当我在Heroku上打开网站时，我收到了令人沮丧的模糊信息＆＃34;我们很抱歉，但出了点问题。＆＃34;

当我做＆＃34; heroku ps＆＃34;它说：

    Process  State       Command                               
    -------  ----------  ------------------------------------  
    web.1    up for 13m  bundle exec rails server thin -p $..

当我跑＆＃34; heroku日志＆＃34;我得到通常的弃用消息，然后是下面的文本。但我在这些日志中看不到会导致应用崩溃的红旗。我错过了什么吗？

Answer 1

您是否迁移了数据库（如果有的话）？这通常会吸引我。： - ）

heroku run rake db:migrate

Answer 2

问题在于我没有显示足够的记录。一旦我运行heroku logs -n 2000（或其他一些大数字），它就向我展示了问题的开始

部署到Heroku时Rails应用程序崩溃，但日志声称一切正常
