Whenever you're using form_for(anObject), you want to use FormHelpers: http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html
Whenever you're using a standalone form that's not tied to a model's attributes (IE, one in which you do not pass the FormConstructor into the block as 'f', on which you'd call f.text_field ) you want to use FormTagHelpers: http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html You're using form_for with an object, which means you should use the 'tagless' versions of the form constructors, but instead you're using f.text_field_tag. The correct syntax is: f.text_field :attribute_name, {value => element.value} However, since you're linking up associations in your form you'll want to use the fields_for helper, to bring the constructor into scope while still referring to the proper element in the form. Read about it here: http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#M001741 Now, since you can set up Forms to 'has_many' Elements, and Elements 'belong_to' a Form, you can make your query like this in your Controller: @form = Form.find(params[:id], {:include => :elements}) And then have the following code in your controller (Or something like it, play with it a bit, I've never done anything exactly like this before) : <%= form_for @form, :action => create do |f| %> <% @form.elements.each do |element| %> <% fields_for element do |e| %> <%= e.label 'value' %> <%= e.text_field :value %> <% end %> <% end %> <%= submit_tag %> <% end %> Play with the params output of that, and adjust your create action accordingly. If that's not pretty enough for you, use HAML: = form_for @form, :action => create do |f| - @form.elemenst.each do |element| - fields_for element do |e| = e.label 'value' = e.text_field :value = submit_tag On Sep 22, 5:23 pm, "Commander Johnson" <[EMAIL PROTECTED]> wrote: > Hi, > Thanks to Erol for giving me input on how to move stuff to a namespace.
