similar to: Form Entity Names for Child Objects

I am just getting started with Rails, don''t know any Ruby, and don''t quite even get object oriented programming yet. I have tweaked my schema to The Rails Way and have generated a bit of scaffolding. I am trying to create a new Part, which references a PartName and a PartNumber. I can create a PartNumber on the fly, but the PartName has to exist. I have an inelegant solution

Hi, I have a question today regarding how the various form elements in _form.rhtml are named. I understand that for a database table "persons" with a column headed by "name", then in _form.rhtml it will probably be like: <p><label for="person_name">Name><br/> <%= text_field ''person'', ''name''
