Research direction

Start by locating where DATABASE_URL is assembled and read the surrounding database connection setup. Check how the URL is consumed and whether the project has tests for connection configuration. Done means credentials containing special characters no longer produce a malformed connection URL.

🌟 Feature Description

Enhance the database connection setup by safely encoding sensitive credentials (such as the database password) using urllib.parse.quote_plus. This ensures that special characters in credentials do not break the database connection URL.

🔍 Problem Statement

Currently, database credentials are interpolated directly into the connection string:
DATABASE_URL = f"postgresql+asyncpg://{USER}:{PASSWORD}@{HOST}:{PORT}/{DBNAME}"

If the database password contains special characters like @, :, /, #, or %, the connection string becomes malformed, leading to confusing runtime errors such as:
socket.gaierror: nodename nor servname provided

This issue is hard to debug and commonly occurs with managed databases like Supabase, where passwords often include special characters.

🎯 Expected Outcome

  1. Database credentials, especially the password, are safely URL-encoded before being used in the connection string.
  2. Prevents connection failures caused by malformed URLs.
  3. Improves robustness and developer experience when configuring environment variables.
