Deploy Django on Google App Engine Standard with Cloud SQL PostgreSQL by configuring Unix socket connections in app.yaml and settings.py, using Gunicorn for production serving. This setup ensures secure and efficient data handling for GCP deployments.

Django Cloud SQL connections fail with No such file or directory when Unix socket paths are misconfigured. Ensure your settings.py references the correct /cloudsql/ instance connection name format and that your app.yaml specifies the proper cloud_sql_connections environment variable.

Yes, use Cloud SQL Auth Proxy for local Django development to securely connect to PostgreSQL instances. It forwards local requests to your Cloud SQL database, preventing connection refused errors and ensuring your local environment mirrors production behavior.

Configure Django settings.py for Cloud SQL PostgreSQL on GAE Standard by setting the database engine to postgresql and directing the HOST to the Unix socket directory. Pre-configured templates ensure proper Gunicorn setup and production-ready database connection handling.

Fix connection refused errors during local Django Cloud SQL testing by running the Cloud SQL Auth Proxy alongside your development server. This establishes a secure local forwarding tunnel to your PostgreSQL instance, mirroring the App Engine production environment.
