Slick Queries With GroupBy - scala

Question

I'm new to Scala and Slick. I'm trying to run a query with a grouping by an object and creating two sequences for each object.
This is my code :
val firstQuery = {
for {
table1Id <- Table1.filter(_.someid === someid).map(_.someid)
table2 <- Table2.filter(_.someid === table1Id)
table3 <- Table3.filter(_.someId === someid)
_ <- {
Table4.filter(table4 => table4.someid === table3.someid &&
table4.name === "$$$")
}
table5 <- Table5.filter(_.someid === table2.someid)
} yield {
(table2, table3, table5)
}
}
val finalQuery = {
for {
(table6, firstQueryTuple) <- {
Table6 joinRight firstQuery on
((firstTable, secondTable) => firstTable.someid === secondTable._1.someid)
}
} yield {
(table6, firstQueryTuple._1, firstQueryTuple._2, firstQueryTuple._3)
}
}
dataBaseConnection.run(finalQuery.result).map { resultSequence =>
val grouping = resultSequence.groupBy { case (table6, table2, _, _) => (table6, table2) }
val groupingFiltered = grouping.map { case (table6table2tuple, sequence) => (table6table2tuple, sequence.map(_._4) (which is Table5), sequence.map(_._3) (which is table3)) }.toSeq
groupingFiltered match {
case tupleQuery if tupleQuery.nonEmpty => Success(tupleQuery.map(x => (x._1._2, x._1._1, x._2, x._3) ))
case _ => Failure(NonEmptyList(DBMissingRecordProblem(s"Error")))
}
}
Now what I need to achieve is this result
Seq[(Table2, Option[Table6], Seq[Table5], Seq[Table3])]
Is there a way to group by and achieve two sequences? I know it can be done for one sequence, I mean group by an object and achieve (object, Seq[anotherObject])
Please help me if you can.
