I am trying to build a form with Play Framework 2, the usual syntax is:
@helper.form(action = routes.Application.submit, 'id -> "myForm") {
}
Note that the single quotation mark is before id is opened and never closed.
Is there another syntax that I can use to do the same thing?
The 'id is a Symbol.
You could use the Symbol("sym") syntax if you don't like this one, but it is not standard.
scala> 'symbol == Symbol("symbol")
res0: Boolean = true
You could work around it with an implicit conversion. This will require using a scala source file, though (seems like you're using java, but you can mix them).
app/libs/SymbolImplicits.scala
package example.libs
object SymbolImplicits {
implicit def string2Symbol[A](s: (String, A)): (Symbol, A) = (Symbol(s._1), s._2)
}
Then in your view you would @import example.libs.SymbolImplicits._, so you can then do:
@helper.form(action = routes.Application.submit, "id" -> "myForm") {
}
"id" -> "myForm" is then implicitly converted to 'id -> "myForm".
To avoid using that import in every view, you could also add this line to build.sbt (or in Build.scala project properties) instead:
TwirlKeys.templateImports += "example.libs.SymbolImplicits._"
No, that's required syntax for Scala's Symbol as pointed in other answer, anyway except that it looks weird for it's perfectly valid and there's no reason to fight with it.
