Hi ! I have a similar situation. (disclaimer:-- I have tried turbogears & web2py before. But could not find the following functionality there. So I have signed-in here to see whether I can get it in django).
My form is composed of fields from various tables. When a user interacts with form, he/she may add/edit/delete/keep unchanged certain fields, After saving the form, I need to understand--- 1) which table(s) should receive SQL add statement, 2) which one(s) need update stmt, 3) which one(s) to receive delete stmt. Some examples of (desktop) frameworks having this feature:-- i) CursorAdaptor in VFP ii) DABO desktop framework But I am looking for a web framework having this feature. Without a proper method (rather class) to handle it, it would be very messy. There will be code repetitions, etc. I am eager to know whether there is any facility to do the above thing in django. In that case, I will happily switch to django. Any comments/advise/knowledge-sharing highly appreciated. Thanks.
