Installation

pip install django-supabase

Quick Setup

Add to INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    'django_supabase',
    'django_supabase.auth',
]

Configure Settings

SUPABASE_URL = 'https://your-project.supabase.co'
SUPABASE_KEY = 'your-publishable-or-anon-key'
SUPABASE_SECRET_KEY = 'your-secret-or-service-role-key'  # server-side only

# Recommended default: ask Supabase Auth to validate bearer tokens.
SUPABASE_JWT_VERIFICATION = 'auth_server'

# Optional for projects using asymmetric JWT signing keys:
# SUPABASE_JWT_VERIFICATION = 'jwks'
# SUPABASE_JWT_ALGORITHMS = ['RS256', 'ES256']

# Legacy/local-only fallback for HS256 shared-secret verification:
# SUPABASE_JWT_VERIFICATION = 'jwt_secret'
# SUPABASE_JWT_SECRET = 'your-jwt-secret'

AUTH_USER_MODEL = 'supabase_auth.SupabaseUser'

AUTHENTICATION_BACKENDS = [
    'django_supabase.auth.backends.SupabaseAuthBackend',
    'django.contrib.auth.backends.ModelBackend',
]

DATABASES = {
    'default': {
        'ENGINE': 'django_supabase.db.engine.SupabasePostgreSQLEngine',
        'NAME': 'postgres',
        'USER': 'postgres',
        'PASSWORD': 'your-password',
        'HOST': 'db.your-project.supabase.co',
        'PORT': 5432,
    }
}

STORAGES = {
    'default': {
        'BACKEND': 'django_supabase.storage.backends.SupabaseMediaStorage',
    },
    'staticfiles': {
        'BACKEND': 'django_supabase.storage.backends.SupabaseStaticStorage',
    },
}

Run Migrations

python manage.py migrate
python manage.py create_storage_buckets

Usage Example

Authentication

from django.contrib.auth import authenticate

# Email/Password login
user = authenticate(email='[e-mail]', password='password')

# JWT Token authentication (in views)
# Token automatically extracted from Authorization: Bearer <token>

Frontend OAuth

Use Supabase Auth in the frontend with a publishable key. After OAuth login, send the Supabase session access token to Django:

const { data, error } = await supabase.auth.signInWithOAuth({
  provider: 'google',
  options: { redirectTo: 'https://your-frontend.example.com/auth/callback' },
})

const { data: sessionData } = await supabase.auth.getSession()

await fetch('/api/me/', {
  headers: {
    Authorization: `Bearer ${sessionData.session.access_token}`,
  },
})

Django validates the bearer token through SupabaseAuthMiddleware and syncs the local user by Supabase sub / user.id, not by email alone.

File Upload

from django_supabase.storage.utils import upload_file_to_supabase

file = ...

url = upload_file_to_supabase(file, 'media', path='uploads/')

Direct Supabase Queries

from django_supabase.db.client import get_supabase_client

supabase = get_supabase_client()
response = supabase.table('posts').select('*').execute()

Test

# supabase_integration/tests.py
from django.test import TestCase
from django.contrib.auth import get_user_model
from django_supabase.db.client import get_supabase_client

User = get_user_model()

class SupabaseIntegrationTestCase(TestCase):
    """Base test case with Supabase utilities"""
    
    @classmethod
    def setUpClass(cls):
        super().setUpClass()
        cls.supabase = get_supabase_client()
    
    def create_test_user(self, email='[e-mail]'):
        """Helper to create test users"""
        return User.objects.create_user(
            username=email,
            email=email,
            password='testpass123'
        )
