Ross said, you would need @user[:form2][:important_data]. But also remember that you can do: <% form_for :user do |form| %> <%= form.text_field .... %> <% fields_for :user2 do |form2| %> <%= form2.text_field .... %> <% end %> <% end %> and then you''ll have params[:user] and params[:user2] separately.

You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.[] i did read about fields_for and also saw it implemented on railscast.com but i not sure how to implement with a drop down menu. thanks for all the suggestions --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I read the form2 as part of the user form, but now see that it is a completely different one. Or at least that''s what I deduce from the naming. In any case, the immediate solution to your problem is to use: params[''form2''][''important_data''] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
