Heroku - Set Procfile to run a Django Command to create DB - django

Question

I'm deploying my DjangoApp to Heroku.
I'm following all the documentation but not sure how to set the Procfile to run my command, as I do locally to create my shop_peru DB:
This is what I do locally to create the Peru DB:
python manage.py ubigeo_peru
This is my Procfile:
release: python manage.py makemigrations
release: python manage.py migrate
release: python manage.py ubigeo_peru
web: gunicorn stickers_gallito.wsgi --log-file -
ubigeo_peru.py:
import pandas as pd
import csv
from shop.models import Peru
from django.core.management.base import BaseCommand
tmp_data=pd.read_csv('static/data/ubigeo-peru-2018-12-25.csv',sep=',', encoding="utf-8")
class Command(BaseCommand):
def handle(self, **options):
products = [
Peru(
departamento=row['departamento'],
provincia=row['provincia'],
distrito=row['distrito'],
)
for idx, row in tmp_data.iterrows()
]
Peru.objects.bulk_create(products)
When deplying to heroku I get this error:

Answer 1

You cannot use sqlite database in Heroku. Use on of the databases they provide.
I generally use postgresql
heroku addons:create heroku-postgresql:hobby-dev
This will create an empty database for you
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
}
}
# add this
import dj_database_url
db_from_env = dj_database_url.config()
DATABASES['default'].update(db_from_env)
This is will change the database in your setting.py
