使用Anorm的SqlParser出现问题

Question

I'm trying to parse some SQL and save it as PushMessage (which is a class, not a case class - don't know if that matters). Following the Anorm documentation I have

 implicit val parser: RowParser[PushMessage] = Macro.namedParser[PushMessage]

  val result = db.withConnection { implicit connection: Connection =>

    SQL"select * from PUSH_MESSAGES where VENDOR_ID=$requestedVendorId;".as(parser.*)
  }

However, I'm getting a problem as IntelliJ tells me that Macro.namedParser[PushMessage] returns an Any, and not a RowParser[PushMessage]. I tried removing the declaration type, but then I couldn't run the parser using the .as(parser.*) syntax.

How do I get this to return a RowParser?

Thanks in advance,

I guess you are using an Anorm version before 2.5.1 (April 2016), when the macros have been updated to use whitebox context . In such case, your IDE cannot properly infer the return type.

Note that Anorm 2.5.2 has just been released .
