I have a somewhat similar situation. In my form, fields from various database tables are combined. A user may add/edit/delete/doesn't change fields. While saving the form, the logic should check-- 1) which table(s) would require add SQL statement, 2) which table(s) require update stmt, 3) which one(s) require delete stmt.
At present, I am using some other web framework. There, I need to do the circus of deriving the above statements. Although one can write a class for the above, I would be happy if something similar is already there in django. In such a case, I may abandon my present framework & switch to this web framework. Does anybody know about such a facility here? Any comments / response highly pappreciated.
