I got this following error while trying to add a non-nullable field (description) to an existing model (Category) without specifying a default value.
it is impossible to add a non-nullable field 'description' to category without specifying a default. This is because the database need something to populate existing rows.
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) Quit and manually define a default value in models.py
select an option:
description=models.TextField(max_length=500,blank=False)UPDATE:
description=models.TextField(max_length=500,blank=False,null=True)
You need to run python manage.py makemigrations followed by python manage.py migrate to apply the changes to your database.
