User Models in SailPilot
========================

The User models in SailPilot's backend encompass functionalities related to user data management and interactions with other components of the application. They are pivotal in managing authentication, user profiles, and user-related transactions.

Profile Model
-------------

The `Profile` model extends the default Django `User` model, adding additional fields such as date of birth, contact information, and address. It is linked to the `User` model via a one-to-one relationship, ensuring each user has one associated profile.

- **Fields**: Includes date of birth, phone, fax, address, city, area, zip code, and country.
- **Signals**: Utilizes Django's signals to automatically create and update the `Profile` instance when a `User` instance is created or saved.

UserPurchases Model
-------------------

The `UserPurchases` model tracks the purchases made by users within the application. It is crucial for managing the commercial aspect of the application, recording transaction details, and linking to the `FeatureLibraries` model.

- **Fields**: Includes user (linked to Django `User`), purchase date, country, area, and language.
- **Relation**: Has a foreign key relationship with the `User` model and the `FeatureLibraries` model.
- **Database Table**: The model uses a custom database table `user_purchases`.
