FlashMapSupport

org.scalatra.FlashMapSupport

See theFlashMapSupport companion object

trait FlashMapSupport extends Handler

Allows an action to set key-value pairs in a transient state that is accessible only to the next action and is expired immediately after that. This is especially useful when using the POST-REDIRECT-GET pattern to trace the result of an operation.

post("/article/create") {
 // create session
 flash("notice") = "article created successfully"
 redirect("/home")
}
get("/home") {
 // this will access the value set in previous action
 stuff_with(flash("notice"))
}
