Play 2.0.1 custom field constructor... Extra parameters?
java, playframework-2.0, twitter-bootstrap
Solution
You're passing the parameter in the right way. But the additional parameters are stored in `@elements.args`. So you have to use `@elements.args.get('_iconcls)` to read your parameter.
Problem
I am new to the play framework and want to write my own twitter bootstrap field constructor, which includes the usage of the bootstrap icon-classes. To make this dynamic I need to pass the icon-class via extra parameter. Is that even possible? I tried the following and some other variations: index.scala.html ``` @(loginForm: Form[Login]) @import helper._ @implicitFieldConstructor = @{ FieldConstructor(twitterBootstrapInput.render) } @main("Akquise") { <div class="container row"> <div class="span4 offset5"> @form(routes.Application.login(), args = 'class -> "well"){ <h3>Anmeldung</h3> <fieldset> @inputText(loginForm("username"), '_label -> "Nutzername", '_iconcls -> "icon-user") @inputPassword(loginForm("password"), '_label -> "Passwort", '_iconcls -> "icon-key") </fieldset> <button type="submit" class="btn btn-primary">Login</button> } </div> </div> } ``` twitterBootstrapInput.scala.html ``` @(elements: helper.FieldElements) @************************************************** * Generate input according twitter bootsrap rules * **************************************************@ <label for="@elements.id">@elements.label</label> <div class="input-prepend"> <span class="add-on" style="margin-right:-5px;"> <i class="@elements.iconcls icon-size"></i> </span> @elements.input </div> ``` With these parameters the compiler throws this error: `value iconcls is not a member of views.html.helper.FieldElements` How can I pass other arguments if that doesn't work?
