Java Play 2 - Function as a parameter in scala

I have problems to write reusable code in scala.

If i have something like

@helper.form(action = routes.Guides.addComment(category,title)) {

Is there a way to replace it with a variable?

pseudo code

@(func : Function)
@helper.form(action = func) {

Edit:

Oh.... now it's kinda obvious. The function itself should return a string , so I guess i can just say something like this

@(func :String)
..

.

return ok (form.render(routes.Guides.test()))

Testing it now

May I suggest an alternative? Use Call directly.

@(route: Call)

@helper.form(action = route) {
  ...
}

In Scala, you could even pass only a part of the route and fill the rest from the controller (very useful when you're using pagination).

figured it out.

with 

routes.Guides.test().url

you get the url and then you can use it as a parameter

for example

@guidesComment((routes.Guides.addComment(ug.category,ug.title)).url)

guidesComment looks like this

@(func: String)

Then use it like this

<form action="@func" method="POST">
