I've been working on a Django project locally and used SQLITE as the database. I've now deployed the project to Heroku-website and used Postgresql as the database. The database schemas have moved over fine but the data from the tables has not migrated.
What is my problem?
Here is my database code from settings file.
DATABASES = {
'default': {
"ENGINE": "django.db.backends.sqlite3",
"NAME": os.path.join(BASE_DIR, "db.sqlite3"),
}
}
import dj_database_url
db_from_env = dj_database_url.config(conn_max_age=600)
DATABASES['default'].update(db_from_env)

Answer 1

You should use engine name only in database while in production.
In settings.py file:
"ENGINE": "django.db.backends.postgresql_psycopg2"
Transfer data from local to production.
Data transfer
Install the Heroku PGBackups add-on:
heroku addons:add pgbackups
Dump your local database:
pg_dump -h localhost -Fc library > db.dump
In order for Heroku to access db dump, you need to upload it to the Internet somewhere.
Import the dump to Heroku:
heroku pgbackups:restore DATABASE http://www.example.com/db.dump
