multiple has_many objects in one form

Hi - I have to models, Question and Answers. A question has many answers. I want to set up a form where a user can submit 1 question and up to 10 answers. So, in the questions controller, I have new:

def new @question = Question.new @answers=   i=0   while i<10     @answers << Answer.new     i += 1   end end

In the form, I'm trying something like:

<% form_for :question do |f|%> Question: <%=f.text_field :question%>

<%for @answer in @answers %>   <%fields_for :answer do|a|%>   Answer: <%=a.text_field :answer%> <br/>   <%end%> <%end%>

<%end%>

The problem is, this doesn't index the answers, the html just shows 10 repeated answer[answer]. Is there a better way?

The second question I have is, how do I validate for at least 1 answer?

Thanks, Dino
