Ashwin,
I had to do something similar in my app. What you can do is create an
object that mimics ActiveRecord in your controller. By that, I mean
the object should have methods with the same names as the attributes
which return the attribute''s value. Then pass that to a form helper,
and you should be golden.
Controller action:
@user = User.new(params[:user]) # User is a class you''ll have to
write
View template:
<% form_for :user, @user, :url => {:action =>
''create''} do |f| %>
<%= f.text_field :username %>
....
<%= f.submit %>
<% end %>
The trick is that `f.text_field :username` will create a text field
and set its value to what is returned by calling `@user.username`.
You can read up more on form helpers here:

I hope that helps,
