play framework - how can i call this function for the authenticated user in this code play2 scala zentasks - scala

Question

in the play2 scala zentasks sample application the code snippet looks like this
def IsAuthenticated(f: => String => Request[AnyContent] => Result) =
Security.Authenticated(username, onUnauthorized) { user =>
Action(request => f(user)(request))
}
What I need to do is call this function in model
def AddOnline(email: String, contact: Contact) = {
DB.withConnection { implicit connection =>
SQL(
"""
update contact
set online_status = {'online'} //I want to write the value contact.status=online
where email = {email}
"""
).on(
'email -> contact.email,
'online_status -> contact.online_status
).executeUpdate()
}
}
But my challenge here is to call this AddOnline function every time a certain user is authenticated by the above piece of code. Can someone suggest how I should go about this? I am a novice in this and I am going round and round in circles without making any progress

Answer 1

You can call the addOnline method from the IsAuthenticated like this:
def IsAuthenticated(f: => String => Request[AnyContent] => Result) =
Security.Authenticated(username, onUnauthorized) { user =>
// Do what you need to do here before the action is called
Contact.addOnline(user)
Action(request => f(user)(request))
}
Please note that the user is not the user object but just the email of the authenticated user.
Also, as you are only adding the online status of the user it looks like you can simplify your AddOnline method to something like this.
def addOnline(email: String) = {
DB.withConnection { implicit connection =>
SQL(
"""
update contact
set online_status = 'online'
where email = {email}
"""
).on(
'email -> email,
).executeUpdate()
}
