Why do I get a Some instead of a String in Scala

Question

Why do I get a [Some] Object instead of a [String] Object?
The Some object won't work as a String Parameter in a method call.

The config def returns a String so I expect the type to be String.
But when I type "Hello" Scala get's it correct.

Code

    def config(s: String) = Play.current.configuration.getString(s).toString()
    Logger.info(config("recaptcha.publicKey"))
    Logger.info("Hello")

Output

[info] application - Some(6LeDMdASAAAAAC4CFIDY-5M7NEZ_WnO0NO9CSdtj)
[info] application - Hello

Answer 1

You are unnecessarily calling toString() on Option[String] (which Play.current.configuration.getString() returns), try this:

def config(s: String) = Play.current.configuration.getString(s).get

or maybe preferably:

Play.current.configuration.getString(s).getOrElse("some default")

Answer 2

getString returns an Option[String], so that it can return an empty value when there is nothing to return. When there is something to return, it returns Some(string) and you can get the inner string using the get() method.
