[https://code.djangoproject.com/ticket/32285 #32285] introduced a new
ImproperlyConfigured exception when an app label isn't a valid python
identifier. This was intended to prevent confusion caused by periods in
app labels.
But, this also prevents using app labels containing things like hyphens,
which seem to still work fine when the check is removed. There's a few
mentions online where this has caused surprises, such as for
[https://github.com/FortAwesome/Font-Awesome/issues/17801 fontawesome] and
[https://github.com/sehmaschine/django-grappelli/issues/957 django-
greppelli]. I suspect this will get worse as we get closer to 3.1 support
ending.
Notably,
[https://docs.djangoproject.com/en/3.2/ref/applications/#django.apps.AppConfig.label
the docs] say the label //should// be an identifier, not that it //must//.
So, what do you think about changing the exception to something that can
be overridden, like a warning or system check? This is still a strong
signal to users about the source of potential problems, but also saves a
lot of pain in cases like mine -- as it stands, I'd need to update
thousands of previously-working references across project source,
migrations, and databases.
I'd be happy to write the patch if we can agree on an approach.
