Play framework : Setting Lang in a helper.form in a scala view

Question

I've got the following code in a view :

@(lang:Lang)...
...
<div>
...
@helper.form(action = routes.item.add) {
     <p>@helper.inputText(myItem("name"))</p>
     ...
    }
...
</div>

In my internationalization files, i have entries for name. e.g. :

in messages.en : name=Name
in messages.fr : name=Nom

The view is always rendered with the french label for this inputText and I don't know how to change for another langage, e.g. using the global parameter lang defined in my view.

I was looking for some solutions like : @helper.form(action = routes.item.add, lang) or the same kind of code at inputText level.

Are you using Scala or Java? With Scala you can set a implicit language. But for Java this is not easy as in Play 1.2.4:

Lang.set(...) or .change()

This will be solved in 2.1: https://play.lighthouseapp.com/projects/82401/tickets/174-20-i18n-add-ability-to-define-implicit-lang-for-java-api

See previous discussion in Google Groups: https://groups.google.com/forum/?fromgroups#!topic/play-framework/dE1SPBaTM6w

Is you use scala have a look at post: i18n error: controller and templates uses different implicit languages

My solution :

@(lang:Lang)...

@import play.i18n._

@translate(text: String) = @{
 Message.get(lang, text)
}
...
<div>
...
@helper.form(action = routes.item.add) {
     <p>@helper.inputText(myItem("name"), '_label -> translate("name"))</p>
     ...
    }
...
</div>

In Play, it's possible to add attribute to the forms with the '_ convention. I have overriden the label using this by applying my own translate function.

Why do you pass the lang as a String? – Marius Soutier Jul 30 '12 at 06:11
Good question : I think it's useless to pass the lang because I've got it in my cookie. I will have a look later and update my answer. Thanks for the idea. But maybe you have another option in mind? – Vincent Biragnet Jul 30 '12 at 12:44
Are you using Scala or Java? I'd pass lang as `Lang` directly. – Marius Soutier Jul 30 '12 at 13:42
I use Java. Following your comment, i update question and answer, thanks for pointing this out. – Vincent Biragnet Jul 31 '12 at 12:43
