当我进入控制台时：
git push heroku master
我明白了：

并应用迁移。
当我在Heroku上访问我的页面时，我看到We're sorry, but something went wrong.
答案 0 :(得分：6)
运行heroku logs并查看错误
答案 1 :(得分：0)
错误日志显示
PG::Error: ERROR: relation "events" does not exist
这意味着您没有创建数据库，甚至您也没有运行迁移。检查你的Gemfile中是否有pg gem。如果没有在Gemfile的生产块中添加gem 'pg'，则Heroku在postgres上运行。
做一个
git push heroku master
THN
heroku run rake db:create
THN
heroku run rake db:migrate
它应该有用。
