slick 3.0 select then insert - scala

Question

I want to insert a new row with different status value if that row exists and return the new instance as Some to the caller. If it does not exist, nothing happens and return None. What I have is
def revoke(name: String, issueFor: String): Future[MyLicense] = {
val retrieveLicense = slickLicenses.filter(l => l.name === name && l.issueFor === issueFor).
sortBy(_.modifiedOn.desc).result.headOption
val insertLicense = for {
licenseOption <- retrieveLicense
} yield {
licenseOption match {
case Some(l) => Some(slickLicenses += l.copy(status = RevokedLicense))
case None => None
}
}
db.run(insertLicense).map {r =>
r.map { dbLicense => MyLicense(dbLicense.name, dbLicense.status)
}
}
How do I fix this?
Edit 1
I changed the code to
override def revoke(name: String, issueFor: String): Future[String] = {
val retrieveLicense = slickLicenses.filter(l => l.name === name && l.issueFor === issueFor).
sortBy(_.modifiedOn.desc).result.headOption
val insertLicenseAction = for {
l <- retrieveLicense
newLicense <- slickLicenses += l.get.copy(status = RevokedLicense)
} yield newLicense
db.run(insertLicenseAction).map(_ => name)
}
Hence, the question changes to how do I get the instance I insert into the database? Thanks

This is what I did finally,
override def revoke(name: String, issueFor: String): Future[String] = {
val retrieveLicense = slickLicenses.filter(l => l.name === name && l.issueFor === issueFor).
sortBy(_.modifiedOn.desc).result.headOption
val insertLicenseAction = for {
l <- retrieveLicense
_ <- l.map(x => slickLicenses += x.copy(status = RevokedLicense,
modifiedOn = new Timestamp(System.currentTimeMillis())))
.getOrElse(DBIO.successful(l))
} yield ()
db.run(insertLicenseAction).map(x => name)}
