It feels like you're doing work that's already done properly when you setup your URLs right.

The operations work like this:

• Create view: doesn't get an instance ID (but creates one) and fills form with values set by defaults keyword argument on model fields.
• Update view: gets an instance ID and fills it with field values from the instance. Any missing values get assigned defaults.
• Delete view: gets an instance ID and removes it. Field values typically do not come into play.

Does this conflict with what you're trying to accomplish?
