Play! framework: define a variable in template?
java, playframework, playframework-2.0, scala, template-engine
Solution
As stated in the Play documentation you can use the `@defining` helper.
@defining(if (event.getSeverity > 0) "green" else "red") { color =>
<div style="background-color: @color">foo</div>
}
Or you can use a `reusable block`
@severityColor(event: Event) = @{
if (event.getSeverity > 0) "green" else "red"
}
<div style="background-color: @severityColor(event)">foo</div>
Problem
I'm passing to a template an `Event` object and what I need to do is checking `@event.getSeverity` value. if the value is positive, I want to color a specific `<div>` in green. if the value is negative I want to color a specific `<div>` in red. I couldn't find a way to define a variable. is it possible? it should be I think. anyhow, what's the simplest way accomplishing this? thanks
