SQL Schema in Django Models

A schema in a SQL database is a list of logical data structures. It's commonly used for security-related management and permissions.

The feature is supported by PostgreSQL and very well by Django. Let's see how to configure schema in Django for a PostgreSQL database.

Creating the database

First, ensure that the database is created.

CREATE DATABASE coredb;

CREATE USER core WITH PASSWORD '12345678';

GRANT ALL PRIVILEGES ON DATABASE coredb TO core;

And let's create a schema.

CREATE SCHEMA AUTHORIZATION core;

CREATE SCHEMA IF NOT EXISTS coreschema AUTHORIZATION core;

We've created coreschema in the coredb database. And only the core user can access the schema for the moment.

Let's see how to use it with Django.

Django models configuration

Naturally, make sure that the Django project is configured with Django. It'll look like this.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'coredb',
        'USER': 'core',
        'PASSWORD': '12345678',
        'HOST': 'localhost',
        'PORT': 5432
    }
}

And when working with a model, use the Meta class to tell Django the name of the database table to use for the model.

class Fruit(AbstractModel):

    name = models.CharField(max_length=100)

    class Meta:
        db_table = "'coreschema.fruit'"

And run the migrations commands. And the table will be created under coreschema.
