Use traditional fixtures for any objects that are not date dependant. https://docs.djangoproject.com/en/1.5/howto/initial-data/#providing-initial-data-with-fixtures Use SQL fixtures for any objects that are date dependant, and specify the date field in terms of "NOW() + INTERVAL 21 DAY" or similar. https://docs.djangoproject.com/en/1.5/howto/initial-data/#providing-initial-sql-data You can use the dumpdata command to create traditional fixtures, the SQL ones you will need to craft by hand.
