Use of option helper in Play Framework 2.0 templates
playframework-2.0, scala
Solution
The right type is: `Seq[(String, String)]`. It means a sequence of pairs of String. In Scala there is a way to define pairs using the arrow: `a->b == (a, b)`. So you could write e.g.:
@select(field = myForm("selectField"), options = Seq("foo"->"Foo", "bar"->"Bar"))
But there is another helper, as shown in the documentation, to build the sequence of select options: `options`, so you can rewrite the above code as:
@select(myForm("selectField"), options("foo"->"Foo", "bar"->"Bar"))
In the case your options values are the same as their label, you can even shorten the code to:
@select(myForm("selectField"), options(List("Foo", "Bar")))
(note: in Play 2.0.4 `options(List("Foo", "Bar"))` doesn't compile, so you can try this `options(Seq("Foo", "Bar"))`)
To fill the options from Java code, the more convenient way is to use either the overloaded `options` function taking a `java.util.List<String>` as parameter (in this cases options values will be the same as their label) or the overloaded function taking a `java.util.Map<String, String>`.
Problem
I'm trying to use `views.html.helper.select` (documentation here). I don't know scala, so i'm using java. I need to pass object of type Seq[(String)(String)] to the template right? Something like: ``` @(fooForm:Form[Foo])(optionValues:Seq[(String)(String)]) @import helper._ @form(routes.foo){ @select(field=myForm("selectField"),options=optionValues) } ``` I don't know how to create Seq[(String)(String)] in java. I need to fill this collection with pairs (id,title) from my enum class. Can somebody show me some expample how to use the select helper? I found this thread on users group, but Kevin's answer didn't helped me a lot.
