Creating and assigning values to a variable in Scala template

I have not been able to solve this specific case from the examples provided in the documentation.

I create a Result:

    Customer customer = new Customer("James");
    Order[] orders = new Order[2];
    orders[0] = new Order("Apple");
    orders[1] = new Order("Orange");
    Content html = views.html.template.render(customer, orders);
    return ok(html);

And my template is:

@(customer: Customer, orders: Array[Order])

<h1>Welcome @customer.name!</h1>

<ul> 
    @for(order <- orders) {
      <li>@order.name</li>
    }
</ul>

Now I want to add a Boolean variable in the template, then iterate through the orders, and if Apple appears in the orders, I want to set the created variable to true.

Basically I need a var that has scope throughout the whole template.

Thank you.

Added some pseudocode.

@(customer: Customer, orders: Array[Order])

<h1>Welcome @customer.name!</h1>

**** var containsApple = false;

<ul> 
    @for(order <- orders) {
      <li>@order.name</li>

      **** if order.name == "apple"
      ****   containsApple = true;

    }
</ul>
