For custom save functionality, your model class can supply a custom 'save' method which executes anything you like; the documentation has some simple examples: http://www.djangoproject.com/documentation/model_api/#overriding-default-model-methods > 3.)

There's nothing built in to Django which does this, and building it into the admin would probably involve quite a bit of work. Writing your own custom view which handles it probably wouldn't be too hard, though. The biggest problem you'll run into is that performance will be bad -- to do this, every save of an instance of the model will have to SELECT all instances of that model and run UPDATE against a potentially large number of them. If you want to set that up, though, a manager method is probably the best way to go (e.g., a method on the model's manager class which takes an instance and a new value for its "order", and then works out which other instances need to change). -- "May the forces of evil become confused on the way to your house." -- George Carlin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
