尝试引导播放时出错！Heroku上的应用程序

Question

我无论如何也不能让Heroku为我的游戏建立一个骨架数据库！使用引导的应用程序。我有一个Bootstrap作业和一些YAML来加载对象，但我得到:-

hibernate_sequence表有什么问题？这不是我创建的表/对象。

这个引导过程在我的本地机器上的Dev中工作得很好。

答案是在配置中设置jpa=ddl，尽管在生产中不能这样做。

# Specify the ddl generation pattern to use. Set to none to disable it
# (default to update in DEV mode, and none in PROD mode):
jpa.ddl=update
