Django PostgreSQL


Example

Make sure to have some packages installed:

sudo apt-get install libpq-dev
pip install psycopg2

Database settings for PostgreSQL:

#myapp/settings/settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'myprojectDB',
        'USER': 'myprojectuser',
        'PASSWORD': 'password',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}

In older versions you can also use the alias django.db.backends.postgresql_psycopg2.

When using Postresql you'll have access to some extra features:

ArrayField         # A field for storing lists of data.
