Molly

molly is simple application that injects a signal after the WSGIHandler is instatiated. What this means for you is that you can definitively know when your application is live and can receive requests.

Installation:

pip install django-molly

Usage:

# settings.py file

INSTALLED_APPS = (
    ...,
    'molly',
    ...
)

# in some apps.py file
...
from molly.signals import application_started


def hello_world():
    print "hello world!!!"

class MyAppConfig(AppConfig):
    def ready(self):
        application_started.connect(
            hello_world, dispatch_uid='my-silly-message'
        )

So now when you run python manage.py runserver or any service that utilizes the django.core.handlers.wsgi.WSGIHandler you should see you message.

Enjoy the ecstacy of it all...
