PostgreSQL and My Django app on heroku is not synching - django

Question

I have a django made app on heroku and I want change the database there from sqlite to postgreSQL.
I have changed the code in setting.py as follows however the data in my local sqlite is still uploaded to heroku.
from socket import gethostname
hostname = gethostname()
if "MY-COMPUTER-NAME" in hostname: #my computer name
# debug
# DEBUG = True
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
ALLOWED_HOSTS = ['*']
else:
# online
# DEBUG = False
import dj_database_url
db_from_env = dj_database_url.config()
DATABASES = {
'default': dj_database_url.config()
}
ALLOWED_HOSTS = ['*']
My commands to deploy
git add -A
git commit -m "Change"
git push heroku master
heroku ps:scale web=1
heroku run python manage.py migrate
heroku open
this is a full code of srtting.py
