Heroku,问题/问题

Question

我被称为Heroku for Ruby on Rails托管,到目前为止我认为我真的会喜欢它.只是想知道我是否有人可以帮助我找出问题所在.

我按照那里的说明在那里创建一个应用程序,创建并提交git,推送代码,它显示在http://mylifebattlecry.heroku.com(虽然我所做的大部分是在/ posts/path当我进入一个新的"帖子"(因为这是一个博客平台)时,我得到500.html错误,基本上一切都关闭了.甚至无法返回我输入帖子的页面.

在我看来,数据库设置有问题.我按照他们的建议做了包括... $ heroku rake db:migrate,什么都没有.

只是想知道是否有人知道我做错了什么.以下是他们提供的参考说明:

安装Heroku gem:sudo gem install heroku为你的应用创建一个新的git存储库(如果你还没有):

cd myapp
git init && git add . && git commit -m "first commit"

创建一个新的Heroku应用程序:

heroku create
Created http://sharp-autumn-42.com/ | git@heroku.com:sharp-autumn-42.git
Git remote heroku added

注意:应用程序的名称是自动生成的; 别担心,您可以随时重命名.

部署代码:

git push heroku master

运行迁移(或其他引导任务):

heroku rake db:migrate

在浏览器中打开已部署的应用程序:heroku open

这是.. $ heroku日志,如果有帮助:

您确定要对所有表进行迁移吗？

你可以做heroku rake db:schema:加载到只加载一个新的模式
