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%\>   
  
\<%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
