dj-database-url is a dsn parser. You can ignore it if you do not use dsn notation for database connection.
settings.py
Rewrite the database connection fragment.
e.g., Instead of
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': os.environ.get('FREIGHTAPP_DB_NAME'),
'USER': os.environ.get('FREIGHTAPP_DB_USER'),
'PASSWORD': os.environ.get('FREIGHTAPP_DB_PASS'),
'HOST': os.environ.get('FREIGHTAPP_DB_HOST'),
'PORT': os.environ.get('FREIGHTAPP_DB_PORT'),
}
}
Replace that fragment with this:
DATABASES = {
'default': dj_database_url.config()
}
