用H2玩Slick(2.6.x):找不到表

要重现错误,请查找 play-slick-todos

play-slick-sample 使用Playframework和Slick实现todo list API端点。为了简化问题,我只实现 index 终结点。

之后 sbt run 完成后,访问 localhost:9000 点击 中的终结点 Application

[error] application -

我知道如何创建表:用于 todos , Await.result(db.run(todos.schema.create)) 做这个工作。但我不知道该把它们放在哪里,我相信这应该通过巧妙的手段来实现。

感谢您的帮助。谢谢您!
