did try stuff in documentation @ https://devcenter.heroku.com/articles/django#django-settings?

import dj_database_url databases['default'] =  dj_database_url.config() 

it says

django settings

next, configure application heroku environment, including heroku’s postgres database. the dj-database-url module parse values of database_url environment variable , convert them django can understand.

make sure ‘dj-database-url’ in requirements file, add following bottom of settings.py file:

settings.py

# parse database configuration $database_url import dj_database_url databases['default'] =  dj_database_url.config()  # honor 'x-forwarded-proto' header request.is_secure() secure_proxy_ssl_header = ('http_x_forwarded_proto', 'https')  # allow host headers allowed_hosts = ['*']  # static asset configuration import os base_dir = os.path.dirname(os.path.abspath(__file__)) static_root = 'staticfiles' static_url = '/static/'  staticfiles_dirs = (     os.path.join(base_dir, 'static'), )
