Using scala template code blocks and values as argument to template call (Play Framework)

Question

I've tried to use both reusable code blocks and reusable values as argument to a function call (another template), but always end up in a compilation error: "illegal start of simple expression".

Let's say I have the header template, which takes a string as argument. It is called this way: @header("My title")

Now, I want "My title" to be the result of a code block, or a value.

For example, I have tried this way for a code block:

@headerText(workbookArea: WorkbookArea, workbookItemName: String) = @{
    workbookArea.className + " > " + workbookItemName
}

@header(@headerText(workbookArea, workbookItemName))

Or that way for a value:

@defining(workbookArea.className + " > " + workbookItemName) { headerText =>
    @header(@headerText)
}

But none of these two code snippets compile. How is it supposed to be done?

Answer 1

That would be easier if you showed us an error, anyway - don't use the @ symbol within the brackets, it should be:

@header(headerText(workbookArea, workbookItemName))
