Generic and Inheritance in scala

Question

I have a generic class Field[T]. Now, I want to created and child class extends Field[T] with one more parameters. But I got compile error

class Field[T](val name: String, val label: String, val required: Boolean, val dataType: DataType[T])

class FK[T](override val name: String, override val label: String, override val required: Boolean, override val dataType: DataType[T], val ref: Type) extends Field[T]

Maybe I don't really understand Scala inheritance and generic. Please help me correct FK class.

1) Too many undefined symbols, not minimal reproducible example 2) You don't invoke Fields constructor anywhere. — Andrey Tyukin

You have to be more specific as to what is being inherited.

... extends Field[T](name,label,required,dataType)
