a new migration file will be generated when set DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

Set in my project settings.
DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField'

When executing the command “makemigrations”, a new migration file will be generated.

The id field type should be specified in the model.

class BatonTheme(models.Model):
     id = models.AutoField(auto_created=True, primary_key=True, serialize=False,  verbose_name="ID" )

Similar issue，When executing the command “makemigrations”, a new migration file will be generated.
The changes of the string in the model field can be directly modified to the migration file '0001_initial. py', which can avoid it.
