Move a site from Sqlite to Postgresql

This procedure assumes you have suitably configured project and virtual environment (with DJANGO_SETTINGS_MODULE environment variable set up) and that your settings module follows the pattern settings/dev_<username>.py. You’ll also need to include the postgresql connector in your project if you’ve not already done so.

Extract the data from the existing database:

django-admin dumpdata > data.json

Create a new postgresql database:

psql -U postgres -c "CREATE DATABASE <database name> TEMPLATE=template0 ENCODING='utf-8';"

Amend your settings/dev_<username>.py file to configure the postgresql database:

vi settings/dev_<username>.py

Configure postgresql settings as follows:

    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': '<database name>',
        'USER': '<database user name>',
        'PASSWORD': '<database password>',
        'HOST': '',
        'PORT': '',

Create the database tables:

django-admin migrate

Flush the database ready to receive the data:

django-admin sqlflush

Load the data:

django-admin loaddata data.json
