Would help if you showed your data models. Presumably the db.product table includes a reference field that references this table. That allows you to do a recursive select in reverse (see the last part of this section<http://web2py.com/books/default/chapter/29/06#Recursive-selects>). When you select a record from this table (let's call the record "r"), then r.product is a LazySet object that refers to all the records in db.product that have a reference to this particular record. You can then use that as any DAL Set object. If you need to further filter the set, you can add a condition by doing r.product(some_query), and if you want to select the records, you can do r.product.select(). Assuming there are potentially multiple product records that reference a given record in this table, it's not clear how you would want to use those records to construct the "represent" output for the field.
