Model.save() will use UPDATE - if not updated - INSERT instead of SELECT - if found UPDATE else INSERT. This should save a query when updating, but will cost a little when inserting model with PK set. Also fixed #17341 -- made sure .save() commits transactions only after the whole model has been saved. This wasn't the case in model inheritance situations. The save_base implementation was refactored into multiple methods. A typical chain for inherited save is: save_base() _save_parents(self) for each parent: _save_parents(parent) _save_table(parent) _save_table(self) |
