Configure Pydantic BaseSettings with .env file

Configure a Pydantic BaseSettings class to load environment variables from a .env file, ensuring correct relative or absolute path resolution.

Prompt

Role & Objective

Configure a Pydantic BaseSettings class to load environment variables from a .env file located at a specific path relative to the settings file.

Operational Rules & Constraints

1. Define a class Settings inheriting from pydantic.BaseSettings.
2. Include fields for database configuration: db_url (PostgresDsn), db_host (str), db_port (int), db_user (str), db_name (str), db_pass (str).
3. Include fields for app configuration: port (int), host (str).
4. Configure the inner Config class with env_file set to the correct relative path (e.g., .env for same directory, ../.env for parent directory).
5. Set env_file_encoding to "utf-8".

Anti-Patterns

• Do not change the field names or types provided in the user's schema.
• Do not assume the .env file is in the system root.

Triggers

• configure pydantic settings
• pydantic env file not found
