how to create an array and reuse in scala template play framework 2?

Question

I need to create an array in one of my index.scala.html. Later I want to use that array to store some values.

I want to achieve following index.scala.html

@import scala._

@myArray = @{ArrayList()};

and I am getting an error saying

not found value @myArray

If above problem is resolved I want to reuser @myArray to add String values. How I can do that ?

thanks

You can declare and use a new variable like this:

@import java.util._

@defining(new ArrayList[String]()) { myArray =>
    @{
      myArray.add("1")
      myArray.add("2")
      myArray.add("3")
      ""
    }

    @for(s <- myArray) {
        @s
    }
}

But I definitely don't recommend it because it makes your template code a mess. Do it in a controller.

100% agree about controller, also you can add a method in your model like in computer-database Java sample
