What's driver are you using? I wish have a try.

@nsadeh Thanks, I went my New Year holiday and want to have a test tody. No problem is the best.

Here is the DBIO extension method implicit https://github.com/slick/slick/blob/4e328e09d8825b4aaa384ab56d157cb9643980dc/slick/src/main/scala/slick/jdbc/JdbcProfile.scala#L61 and here is the method https://github.com/slick/slick/blob/3b3bd36c93c6d9c63b0471ff4d8409f913954b2b/slick/src/main/scala/slick/jdbc/JdbcActionComponent.scala#L86 so if you want to call transactionally,you must confirm the type defined in the implicit method...

@chadjaros change ``` scala def transactionAsync[R](action: DBIOAction[R, NoStream, Nothing]): Future[R] = { database.run( action.transactionally // compiler error ) } ``` to ``` scala def transactionAsync[R](action: DBIOAction[R, NoStream, Effect.All]): Future[R] =...

I think the problem is not slick can support java 8 time. The problem is slick now still support java 6 and 7, support java 8 time will cause build...

~~@adamw I think injection without `F[_]` can simply create a model like~~ ```scala // sealed trait Injection // case class FunctionInjection(val func: Any => Injection, val input: Injection]) extends Injection...

~~In the abstraction of `Injection` with `F[_]`, we can no use to do something like `close`, `release` because `Resource` and many many things will do this for us. It seems...

~~Yes, like `ZManaged[A & B, Nothing, C]`, we just print it as~~ ```scala // val a: Injection = implement ZManaged[X, X, A] // val b: Injection = implement ZManaged[X, X,...

~~tough the email since changing the code above.~~
