Dynamic OR filtering - Slick

Question

Ok, I\'ve got a method with multiple optional arguments like this

def(username: Option[String], petname: Option[String], favouritefood: Option[String])
         


        

Answer 1

Something like this should work. I had to use a similiar fragment in my own code and it is also close to what cvogt proposes in above comment (I think).

val username = Option("")
val petname = Option("")
val ff:Option[String] = None

val default = LiteralColumn(1) === LiteralColumn(1) 

yourTable.filter { it => 
  List(
      username.map(it.username === _),
      petname.map(it.petname === _),
      ff.map(it.ff === _)
  ).collect({case Some(it)  => it}).reduceLeftOption(_ || _).getOrElse(default)
}
