To add to the previous post...make sure that you label you form
correctly, for example:
<% form_for(@person) do |f| %>
<%= f.error_messages %>
<p>
<%= f.label :name%><br />
<%= f.text_field :name %>
</p>
<p>
<%= f.submit "Create" %>
</p>
<% end %>
in the code above, if the @person has a name, the text_field is then
populated with that value. or what you could do is get the choice made
by the user i.e.: <% selected_choice =
@survey.get_choice_for_question(@question) %>
end if it's not nil display it as follows: <% selected_choice_id =
selected_choice.id unless selected_choice.nil? %>
(i have a random number of questions so i use a loop to display each
one and get the appropriate answers and such so you have to adapt my
code to what you have)
I had the same problem and this fixed it for me, so i hope it helps.
if not, show us your code and we'll see how we can help.
