Hi, If I have @answers in my Controller, which is an array of Answer model objects which don''t exist in the DB yet... How do I bind a text_area helper in the View to each Answer? (I''m pre-filling some of the Answers with other data people need to verify before submitting and will insert on POST.) I''ve been able to get the textareas to render but not with the Answer values bound. I''ve tried David''s ADWRR "add ''[]'' to the name which gives errors, I think because there is no PK for the records yet. I''ve also tried adding "index" => @Answers.id to the text_area, but that fails as well. Any help is very much appreciated! DR -- Posted via http://www.ruby-forum.com/.

Either: <% @answers.each do |answer| %> <%= text_area_tag ''answers[]'', answer.text %> <% end %> which will post an array of responses, or <% @answers.each_with_index |@answer, i| %> <%= text_area :answer, :text, :index => i %> <% end %> which will post a hash of answers with answer number keys. If you just want their values, operate on answer.values in your controller. -- We develop, watch us RoR, in numbers too big to ignore.
Thanks very much for your time and the suggestions, Mark! I''ll give these a try tomorrow... Cheers, DRoberts -- Posted via http://www.ruby-forum.com/.
Ok, thanks very much again Mark. The 2nd version above worked... I
think the :method approach is what was needed (I was using "method").
The only change I made was to use brackets as below:
<% @answers.each_with_index {|@answer, i| %>
<%= text_area :answer, :answer, :index =>
@answers[i].id_projects_coi_questions, "cols" => 80,
"rows" => 5, %>
<% } %>
All best.
