Anomaly with makemigrations

[Ismael ABBO]

Problem

Makemigrations command does not see the specific change on models related to this field below but produces migrations for any other fields (even in separated project):

gender = models.BooleanField(
	_('gender'),
	default=True,
	blank=True,
	help_text=_('Designates whether the user is a woman.'),
),

Adding in migration files works fine, but default value does not (while they're applied in ORM according to ​https://docs.djangoproject.com/en/4.1/ref/migration-operations/#addfield)
Then I have added blank=True to counter non-null constraint violation

When I add gender field in the migration files manually, executing makemigrations command again generate a delete of that field gender while I have not removed it in the associate model. Do we assume here that it does not see the field at all from the beginning?

When forcefully staying with that field, trying to run a command to populate database produces :

  File "/usr/local/lib/python3.9/site-packages/django/db/models/base.py", line 503, in __init__
    raise TypeError("%s() got an unexpected keyword argument '%s'" % (cls.__name__, kwarg))
TypeError: User() got an unexpected keyword argument 'gender'

Please, why? Am I wrong somewhere?

Steps to reproduce with my environment project (but optional because I have tried it in separated project aswell):

• dockerized Postgres 14.4
• dockerized Python 3.8
• Use a CustomUser model by following these instructions (which works well) : https://code.djangoproject.com/ticket/25313#comment:24
