部署django应用。 在heroku上（gunicorn，wsgi问题）

Question

I have updated my django application from 1.4.1 to 1.6.5 so far it works properly locally. I am now trying to deploy it to heroku, so I am trying to run the wsgi.py file, but whenever I run it with the following in the Procfile:

web: gunicorn myapp.wsgi:application

It starts and tells me where its listening, but if I try to access the address given, I get the following error:

23:51:27 web.1  |   File "~/site-packages/django/contrib/admin/helpers.py", line 8, in <module>
23:51:27 web.1  |     from django.contrib.contenttypes.models import ContentType
23:51:27 web.1  | ImproperlyConfigured: Error importing module django.contrib.auth.middleware:"cannot import name ContentType"

I tried to use the following in the Procfile:

web: python manage.py run_gunicorn

It ran, BUT this command has been deprecated.

Answer 1

It related with 'ContentTypes' model . Can you inspect the database .. it having the table called 'contenttype' . If it's there then delete it. Before doing the migration again .. make sure 'django.contrib.contenttypes' listed in INSTALLED_APPS
