Fix issue #96: Add create_at and update_at

[cld-vasconcelos]

This pull request fixes #96.

The issue has been successfully resolved. The changes made include adding created_at and updated_at fields to the User model by creating a new abstract model TimestampedModel that contains these fields. The User model now inherits from this new abstract model, ensuring that all instances of User will have these timestamp fields automatically managed by Django. Additionally, a migration file was created to apply these changes to the database schema. Furthermore, a test was added to verify that the created_at and updated_at fields are not None, ensuring that the timestamps are correctly set when a User instance is created. These changes directly address the issue by adding the required fields and ensuring they are tested.

Overview of Changes by OpenHands:

OpenHands has implemented changes to enhance the testing of their models by incorporating feedback aimed at improving test coverage. Specifically, they have added new test methods named test_timestamps to the relevant test files. These methods are designed to assert that the created_at and updated_at fields are not None for instances of the models being tested. This addition ensures that the timestamp fields are correctly set when instances are created or updated, effectively addressing the issue of verifying the functionality of these fields through tests.

Resolution Status:

The changes made by OpenHands appear to have successfully resolved the issues as described. The addition of the test_timestamps methods directly addresses the feedback to ensure the timestamp fields are functioning correctly, and there are no indications of remaining issues related to this specific feedback.
