RemovedInDjango19Warning: Model doesn't declare an explicit app_label
I experienced this issue when running tests and it was simply a matter of changing:
from .models import MyModelto
from apps.myapp.models import MyModel
You are importing models.py before app configuration run.
To fix it, you could import and configure signals in CatalogConfig.ready method.
like this:
signals.py
def someSignal(sender, **kwargs): passapps.py
from django.apps import AppConfigfrom django.db.models.signals import post_saveclass CatalogConfig(AppConfig): name = 'catalog' verbose_name = 'Catalogue' def ready(self): from .signals import someSignal post_save.connect( receiver=someSignal, sender=self.get_model('Category') )you may want to check ready method in documentation
