Passing a List to View in Play Framework - list

Question

So, I'm using the Play Framework in conjunction with MongoDB. I'm attempting to pass a List to my view to loop through and display the rows.
Controller:
public static Result find() {
List<DBObject> results = MongoController.find(MongoController.getLocalConnection("test"), "jobs");
if (results == null) {
redirect("/");
}
return ok(find_job.render(results));
}
The MongoController called above uses the following function (functioning - tried and tested):
public static List<DBObject> find(DB database, String collectionName) {
DBCursor cursor = database.getCollection(collectionName).find();
List<DBObject> items = new ArrayList<DBObject>();
while (cursor.hasNext()) {
items.add(cursor.next());
}
return items;
}
View:
#(results : List[DBObject])
The error I'm receiving is:
Compilation error:
Not found: type DBObject
Does anybody have any pointers please? I apologise - I'm new to this framework.

Twirl templates don't work quite the same way when importing things into the local namespace. By default only the models package, and a few other Play packages are imported into the view namespace. Imports made afterward are not used for the template parameters.
You need to either use the fully-qualified package name:
#(results: List[com.mongodb.DBObject])
Or you can add to the templateImports key in build.sbt. i.e., you'd drop this line into your build.sbt file:
TwirlKeys.templateImports += "com.mongodb.DBObject"
This will add the previous import to all compiled templates. Note that it's for Play 2.3.x. If using 2.2.x, then you'd use the following instead:
templatesImport += "com.mongodb.DBObject"
