Signal not called

[maxthevoice]

I have an issue since I installed the library. The signals are not called anymore. When creating a User, for example, a Profile instance should be created, but it doesn't.

signals.py:

@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        models.Profile.objects.create(user=instance)

tests.py:

class TestCreateUserProfile(TenantTestCase):
    def test_create_user_profile(self):
        user = UserFactory()  # Factory boy
        self.assertIsInstance(user.profile, models.Profile)

settings.py:

SHARED_APPS = (
    'tenant_schemas',
    'dal',
    'dal_select2',

    'django.contrib.contenttypes',

    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'django.contrib.postgres',

    'allauth',
    'allauth.account',

    'django_cleanup',
    'django_extensions',
    'debug_toolbar',
    'localized_fields',
    'rest_framework',
    'rest_framework.authtoken',
    'rest_auth',
    'simple_history',
    'versatileimagefield',
    'timezone_field',
    'ordered_model',
    'django_filters',

    'core',
    'core_project',
    'two_factor_auth',
    'users',
    'controls',
    'occurrences',
    'organizations',
)

TENANT_APPS = (
    'django.contrib.contenttypes',

    'controls',
    'occurrences',
)

INSTALLED_APPS = list(SHARED_APPS) + [app for app in TENANT_APPS if app not in SHARED_APPS]

TENANT_MODEL = 'organizations.Organization'

DATABASES = {
    'default': {
        'ENGINE': 'psqlextra.backend',
        'NAME': env.str('POSTGRES_DB'),
        'USER': env.str('POSTGRES_USER'),
        'PASSWORD': env.str('POSTGRES_PASSWORD'),
        'HOST': env.str('POSTGRES_HOST', 'postgres'),
        'PORT': 5432,
    },
}

ORIGINAL_BACKEND = 'django.db.backends.postgresql'
POSTGRES_EXTRA_DB_BACKEND_BASE = 'tenant_schemas.postgresql_backend'

DATABASE_ROUTERS = (
    'tenant_schemas.routers.TenantSyncRouter',
)

I tried with tenant_schemas.postgresql_backend directly as the main ENGINE, but I got the same issue. So I don't think it's related with psqlextra.

I tried it directly from the admin, and I have the same issue.

Let me know if you need more details.

It's probably related to the fact that we need to use the name of the app instead of the relative path users.apps.UsersConfig.

I think https://github.com/bernardopires/django-tenant-schemas/pull/569 will fix this issue.

apps.py

class UsersConfig(AppConfig):
    name = 'users'

    def ready(self):
        import users.signals

The signals are not imported.

I used Django Tenants library instead. The import of apps is better and don't interfer with signals.
