Access denied to ClearDB database using Python/Django on Heroku

I'm trying to build a webapp on Heroku using Python/Django, and I just followed the tutorial to set up a Django project and push it to Heroku. However, I can never even get to the normal Django "It worked!" screen. Of course, that is because when I check heroku ps, there are never any processes running. There is no Procfile but according to the tutorial, that shouldn't matter for a Django app.

When I run heroku run python manage.py runserver, the following error occurs:

Unhandled exception in thread started by <bound method Command.inner_run of <dja
ngo.contrib.staticfiles.management.commands.runserver.Command object at 0x1ff819

Traceback (most recent call last):

    super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (1044, "Access denied for user '<user>
'@'%' to database 'heroku_<####################>?reconnect=true'")

I did already set my DATABASE_URL to the value of CLEARDB_DATABASE_URL. Also, in the Django settings.py, I added as instructed:

import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}

Any help would be greatly appreciated.

That particular error was fixed after calling ClearDB. Turns out that the ?reconnect=true is only for Rails apps, and should be removed from the DATABASE_URL for Django apps.
