You have a few options to go about doing this. The first and most easy way is by either removing the constraint that the field must exist or create a default site in the field. Both of these options can be done at the model level: http://docs.djangoproject.com/en/dev/ref/models/fields/#null and http://docs.djangoproject.com/en/dev/ref/models/fields/#default The other thing you can do it change the form for the admin to populate the field using a default value or during the save method. You can replace the form by defining it in the form attribute in your ModelAdmin: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#form And you can change the save method in the form: http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#the-save-methodor you can add an initial value to the field: http://docs.djangoproject.com/en/dev/ref/forms/fields/#initial I hope that helps, Michael --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
