Comment:
Hello Ari Pollak, thank you for this ticket. I can see the source of
confusion, but I’d like to clarify that `--check is not a `dry-run`-like
option. As described in the help output:
{{{
$ python -Wall manage.py migrate --help
Updates database schema. Manages both apps with migrations and those
without.
[...]
options:
--check Exits with a non-zero status if unapplied
migrations exist and does not actually apply
migrations.
--prune Delete nonexistent migrations from the
django_migrations table.
}}}
The `--check` and `--prune` options operate independently and are
unrelated. `--check` deals with migrations that exist on disk but have not
been applied to the database, while `--prune` does the opposite, removes
migration records from the database that no longer have corresponding
migration files.
Given this, I don’t see a strong reason to prevent these options from
being used together. If the concern is about unintended deletion, perhaps
what this ticket is really suggesting is a `--dry-run` mode for `--prune`?
