python - Django DB level default value for a column

Question

Django is proving the model field argument default (https://docs.djangoproject.com/en/dev/ref/models/fields/#default) but as I know it will be called every time new object is created via django. If we insert/create a records with raw queries (using django.db.connection.cursor) we will get the exception cause Field 'xyz' doesn't have a default value.

How to represent the db level default value for the column in model. Like db_index.

I hope you guy understand my question.

Answer 1

There is an open ticket 470 to include default values in the SQL schema.

Until this feature has been added to Django, you'll have to manually run alter table statements yourself or write a migration to run them if you want a default value in the SQL schema.

Note that Django allows callables as defaults, so even if this feature is added to Django, it won't be possible to have all defaults in the database.
