PostgreSQL

[YuriiDorosh]

Hi!

I opened settings.py and saw that you use SQLite:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}

It's a bad practice to be honest.

I recommented to use PostgreSQL.
This database is much better suited for professional development.

Your settings should look something like this:

DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.postgresql_psycopg2",
        "NAME": os.getenv("POSTGRES_DB"),
        "USER": os.getenv("POSTGRES_USER"),
        "PASSWORD": os.getenv("POSTGRES_PASSWORD"),
        "HOST": "db",
        "PORT": "5432",
    }
}

But better read the official documentation.
