Passing temporary variable to template

[era.ch...@mindparabole.com]

I have created a temporary variable "count" type int inside controller to hold the result of a method.I am trying to pass that to view "queryResult".I am using " return Results.ok(views.html.queryResult.render(count);",it shows an error "render() in queryResult can not be applied to  (int)".Any help appreciated.

Convert it to a String I would say.

Shouldn't be necessary.  The question I have is, where does ".render" come from?  Is this a Java thing?  I've never encountered it in the Scala API, and I'm wondering how it's defined.  At least on the Scala side, it's all about making sure that the parameters in the signature of the template (the first line) match the arguments you're passing in to it...

For more insight into how Twirl works you can take a look at the code it generates in the target folder, e.g. target/scala-2.12/twirl/main/views/html/index.template.scala.

So render() is simply a synonym for apply()?  That's what I'm getting from looking at the generated code.

In which case, it confirms my point to the original poster: you need to rewrite queryResult.scala.html so that it takes an Int.  Probably all you need to do is alter the first line of the template...
