Where is “hellodjango.wsgi”?

问题

I'm trying to assemble some of the missing pieces in my understanding of how to deploy a Django App to heroku, so that I can launch an instance of Newsdiffs on Heroku.

When I walk through the instructions for running Django on Heroku they have you add a line to Procfile that reads thus: web: gunicorn hellodjango.wsgi --log-file -

But there's no actual file named "hellodjango.wsgi" so ... in that tutorial, where is the "hellodjango.wsgi" module created?

And, perhaps more to the point, why is heroku local balking that I have web.1 | : No module named newsdiffs.wsgi when newdsdiffs/wsgi.py definitely exists.

I can launch the app locally with python website/manage.py runserver but if I do gunicorn newsdiffs.wsgi I get the following, which doesn't include any obvious indications (to my eye) of what I'm doing wrong:

(venv)amanda@mona:newsdiffs$ gunicorn newsdiffs.wsgi

回答1:

The gunicorn command takes the name of a Python module, not a path to a file. If hellodjango.wsgi is the name of the Python module, the corresponding file will be hellodjango/wsgi.py or hellodjango/wsgi/__init__.py.

This is the same syntax used to refer to a module when importing it, e.g. you would import * from hellodjango.wsgi to get access to the things defined in hellodjango/wsgi.py.

The django-admin startproject command will create a wsgi.py file in the same directory as the project's settings.py and urls.py files.
