Not working with Django 4.1

[marcusaram]

Django has removed de installed property from the Model Options object (_meta). And will produce the following error when using Django Activity Stream

AttributeError: 'Options' object has no attribute 'installed' this comes from actstream/registry.py line 60 (version 1.4.1).

See this commit from Django django/django@8e3b1cf

[marcusaram]

ive backed out the PR after getting some errors in the feed tests
actstream/tests/test_drf.py:107
[ErrorDetail(string='Invalid model - model not available.', code='invalid')]
needs some more testing but django4.1 seems to b working in the test suite but gotta make sure its testing that method

[marcusaram]

Is this still an issue? I really don't understand why this change will cause issues since Django's code on the property installed was just checking if app_config is not None. But on what env is that test failing?

Any update on this?

For those who also face this before they make django 4.1 release and still want to use django 4.1, maybe this could help:

from django.apps import AppConfig

def is_installed(model_class):
    return model_class._meta.app_config is not None

class MyAppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'myapp'
    def ready(self):
        from actstream import registry
        registry.is_installed = is_installed
        registry.register(self.get_model('mymodel'))
