Slick中的编译查询

Question

我需要在Slick中使用Play和PostgreSQL编译一个查询

val bioMaterialTypes: TableQuery[Tables.BioMaterialType] = Tables.BioMaterialType

def getAllBmts() = for{ bmt <- bioMaterialTypes } yield bmt

val queryCompiled = Compiled(getAllBmts _)

但在Scala IDE中，我在Apply of Compiled

中收到此错误

Multiple markers at this line
- Computation of type () => scala.slick.lifted.Query[models.Tables.BioMaterialType,models.Tables.BioMaterialTypeRow,Seq] 
 cannot be compiled (as type C)
- not enough arguments for method apply: (implicit compilable: scala.slick.lifted.Compilable[() => 
 scala.slick.lifted.Query[models.Tables.BioMaterialType,models.Tables.BioMaterialTypeRow,Seq],C], implicit driver: 
 scala.slick.profile.BasicProfile)C in object Compiled. Unspecified value parameters compilable, driver.

你可以简单地做

val queryCompiled = Compiled(bioMaterialTypes)
