When `manage.py migrate` is called with `--noinput` or `no-input`, it
deletes stale modules by default. This is not documented in the official
documentation (https://docs.djangoproject.com/en/2.2/ref/django-admin
/#cmdoption-migrate-noinput) and it's a dangerous feature.
Other tickets have mentioned the addition of parameters like `--force` to
force the deletion. I think either that approach or the use of other
parameters should be preferred.
The ticket #25036 about deletion of stale content types was closed a long
time ago without further comment, for which I assume the automatic
deletion was discarded as dangerous.
The ticket #29556 about having `--no-input` in `remove_stale_contenttypes`
automatically remove the stale content types was closed as fixed. I wonder
whether the changes to fix that ticket affected the behaviour of the
`migrate` command...
The tickets #29470 and #29026 comment about the output of the commands
when `--no-input` is given. I think the output of `migrate` should list
the stale elements without removing them.
''I'm recording this bug with a Django version of 2.2 because we cannot
use a newer release (issues with other libraries). But, as I haven't found
any mention about this specific issue in other places, and the
documentation part has not been changed between 2.2 and 3.1, I think the
bug is still present (or at least the documentation is not specific about
it).''
Thank you for your time.
