I'm struggling understanding the model view of a combined model. Take the following: class P4 < ActiveRecord::Base has_many :p4_priorities end I figured out the naming and referencing of the sub models (i.e. P4.p4_priorities - seems simple enough but I had weird issues related to it). I'm all ok except that I am having issues with how to reference a 'sub-model' in a form field. This is what I have: <%= text_field 'p4_p4_priorities', 'detail', :size => 75 %> No errors - it's just not saving which tells me the framework isn't understanding what to save. Can you help? Also, the models associated with the related tables have validation but that doesn't apparently roll up into the combined edit I am providing. Is that expected? If so, how do I reference those fields in validation in this model? Just a typical dereference as mentioned above? _______________________ Brad Eck Sr. Software Engineer Pelco 3500 Pelco Way Clovis, CA 93612 Office - 800-289-9100 Email - email@example.com <BLOCKED::mailto:firstname.lastname@example.org>

That's equivalent to saying: <%= text_field 'all_rock_musicians_in_the_world', 'firstname' %>, which doesn't really make sense. Your best bet is to put this in a partial form, and call it with: render(:partial => 'priority', :collection => @p4.p4_priorities) The partial would then have text_field, etc, etc, to deal with a single priority: <% @priority = priority -%> (The helpers require instance variables.) <%= text_field 'priority', 'detail', :index => priority_counter, :size => 75 %> When you're done, you'll have a numbered array of those fields, one per "p4_priority"
