os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'djtest1.settings')
#Specifying the settings here means the celery command line program will know where your Django project is. 
#This statement must always appear before the app instance is created, which is what we do next: 
from django.conf import settings
 
app = Celery('djtest1')
 
app.config_from_object('django.conf:settings')
#This means that you don't have to use multiple configuration files, and instead configure Celery directly from the Django settings.
#You can pass the object directly here, but using a string is better since then the worker doesn't have to serialize the object.
 
app.autodiscover_tasks(lambda: settings.INSTALLED_APPS)
#With the line above Celery will automatically discover tasks in reusable apps if you define all tasks in a separate tasks.py module.
#The tasks.py should be in dir which is added to INSTALLED_APP in settings.py. 
#So you do not have to manually add the individual modules to the CELERY_IMPORT in settings.py.

# This will make sure the app is always imported when
