You are missing parenthesis after 'IntegerField', that's why the 'price' column did not get created So people check for these silly mistakes as well while creating models.

Did you rename order.date_orderd to order.date_ordered (a DateTimeField)?

Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Ignore for now, and let me handle existing rows with NULL myself (e.g. because you added a RunPython or RunSQL operation to handle NULL values in a previous data migration) 3) Quit, and let me add a default in models.py Select an option: sir how can i handle this...
