Say, I have two tables: vendors and products. Now I want a list of all the vendors that have no products yet. This can be seen from the products table if there are no records with the vendor_id of the vendor in question. Is this possible with a 'normal' manager method or with a relationship or do I have to hand-code the SQL?
And if I have to hand-code it with get_objects_from_sql -- can you give me a hint, what would be a good (fast, portable) SQL to do this kind of query (my SQL isn't that good). And how can I make the resulting method a method of my "Vendors" class (I don't use separate manager classes)?
