my Procfile:
Incorrect
web: gunicorn mysite.mysite.wsgi
Solution
web: gunicorn --chdir mysite mysite.wsgi
the ch-dir mysite being the key difference and from my understanding, forcing gunicorn to specifically target mysite/mysite for the wsgi.py
my wsgi.py:
import sys
from django.core.wsgi import get_wsgi_application
path = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
if path not in sys.path:
sys.path.append(path)
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
application = get_wsgi_application()
and my directory: picture of my directory, Procfile on same level as manage.py
Any assistance or direction is greatly appreciated
changing my Procfile to
web: gunicorn --chdir mysite mysite.wsgi
resolved the ModuleNotFound: no module named 'mysite.settings' by changing the current working directory to the parent mysite. Thanks to both of you for your assistance, even though it didn't solve the issue directly, it pointed me in the right direction.
