For example, I have a User class and when you''re creating a new user I want to use fields_for to add a BillingAddress to the user like so: <%- fields_for :billing_address do |billing_address_form| -%> <%= render :partial

I''m trying to build something similar to a Facebook messaging app, in which the view displays all the messages for a particular thread, with a form box for replying at the bottom of the thread. The problem is that using fields_for generates form fields for each existing record, and for one new record. In this case, there is no need to edit existing messages - just a need to add new

Hello, I think this is an easy one for the average Rails developer but I''m a bit stuck.

Hi, I have been watching the last three episodes on railscasts.com in which he goes through dealing with multiple models in one for using fields_for, and virtual attributes. (http://railscasts.com/episodes/ 73). Here is an example of the way they suggest to go about it: # projects_controller.rb def new @project = Project.new 3.times { @project.tasks.build } end def create @project =

I''m trying to use ''fields_for'' in a form. I want the same form to support both the creation of new obejcts as well as the editing of old ones.
