Declare variable to use inside #helper.repeat - PlayFramework - scala

Question

I want to use helper.repeat to create several input elements. But I want to declare the input tags as html instead of using #helper.input methods. But to do that I have to use a #index inside this loop. I am unable to instantiate and increase this variable. I tried something like the code below but I this output appear in html page:
BaseScalaTemplate(play.twirl.api.HtmlFormat$#5a8a0ced) = {0}
is output in html.
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
#index = {0}
#helper.repeat(questionForm("answer.alternatives"), min = 7) { (alternative) =>
<div class="checkbox">
<input type="checkbox" value="#alternative("correct") ">
<input type="text" id="answer_alternatives_(#index)_text" name="answer.alternatives[#index].text" value="">
</div>
}
</div>
</div>
Is there another maybe cleaner way to do what I want? Maybe with #for?
I use playframework 2.4.6 with Java8.

Answer 1

Playframework will let you do what you need, but you will have to do it in another way.
1) Your form definition will have a Seq[String] to save the results that come from the template.
2) Your form definition will need to include this change. In your case:
"answer_alternatives" -> seq(nonEmptyText)
3) Change the name and id from the template to #{alternative.name} so Playframework can link your input text to the sequence of String.
<input type="text" id="#{alternative.name}" name="#{alternative.name}" value="">
