passing map containing user defined object as value to play framework2 scala template

Question

I am using play framework v2.2 and trying to pass a map to a scala template. The map has a string as its key and a user defined object as its value. My controller is in Java - the template is in Scala.

Controller:

 Map<String, UDObject> myMap = new HashMap<String, UDObject>();
 UDObject ud1 = new UDObject(a,b,c);  
 myMap.put("abcd", ud1);
 return ok(index.render(myMap));

Index.scala.html Template:

@(myMap: Map[String, UDObject])  

When I try reload/eclipse or use play run/start - I get a compilation error complaining that the template could not find the user defined object UDObject. Any idea what I am doing wrong?

Answer 1

You need to use the fully qualified name in the declaration of the parameters in the Play template, e.g:

@(myMap: Map[String, com.example.UDObject])  

Unfortunately there is no way to import it, so anything that isn't in the model, view or Scala namespace must use the full name.

Answer 2

It is possible to add this import for all your templates as well.

templatesImport ++= Seq("com.example.UDObject")

Now you don't need to use the fully qualified name of your class.
