Current route / call in Play Framework 2.0

[EECOLOR]

Hello,

I can not find a way to get the current route / call from within an
action. How can I get from a request to a route / call?

This would be helpful for libraries that need to perform some work
(login or something) and then redirect back. It would also be handy
for navigation and setting the correct element in the navigation to an
active state.


Thanks,


Erik

It turns out this can be done easily:

Call(request.method, request.path + "?" + request.rawQueryString)

Could you elaborate a little more? is that a Scala call? I couldn't find a Java equivalent to that.

Thanks.

Yes, in Scala there is a type of class called a 'case class'. This creates a 'companion' object with the same name and an apply method. Companion object means: an object with the same name that can be accessed in a static fashion. The apply method is executed if you call a method without a name on an object.

The call class is defined like this: case class Call(method: String, url: String) { }

The equivalent of this without the case keyword would be a class and an object:

class Call(method: String, url: String) { }

object Call {

   def apply(method: String, url:String):Call = new Call(method, url)

}

This means that Call(..., ...) has the same result as new Call(..., ...), which is an instance of Call.

My guess is that the Java equivalent would look something like this: 

new Call(request.method(), request.path() + "?" + request.rawQueryString())

Hi Erik,

The call usage you have given above is to create a new Call with a known url, but do you know how to get the full url given a call or route. I tried to achieve this using  reverse routing using the the code "controllers.routes.Secure.Login().url" but it returns only the "/login" and not the full url. Any thoughts on how to get the full url.  I am trying to pass the full url to a thirdy party library.

Thanks

The call class has a method called 'absoluteURL' which is defined like this:

def absoluteURL(secure: Boolean = false)(implicit request: RequestHeader) = {
    "http" + (if (secure) "s" else "") + "://" + request.host + this.url
}

You could probably use that.

If any committer of the play framework happens to read this. I would suggest that the implementation is changed to something like this:

def absoluteURL(secure: Option[Boolean] = None)(implicit request: RequestHeader) = {

     secure.map( if(_) "s" else "" ).map("http" + _ + ":").getOrElse("") + "// + request.host + this.url

}

This way it defaults to http or https depending on the current url.
