Hi All, I''m running into some issues with a fairly complex database structure. I have 4 tables: Products - id - name Productsitems - id - product_id - name Units - id - product_id - serialnumber Unitparts - id - productsitem_id - unit_id - partnumber - serialnumber What I''m attempting to do is to create a page where, after selecting which product I''m entering, I get presented with the data entry for a new unit and the appropriate number of unitparts for that product as defined by productsitems. The issue is that I need to somehow, in the view, link the partnumber and serialnumber fields back to the appropriate productsitem and then to parse them out so that those ids make it into the database. In other languages I would simply enumerate my fields and parse the resulting variable names - is there a simple way to do this in Rails? Thanks, Mike
