Refactor Logging and Enhance CRUD Repository with Tests

Summary

This PR introduces key updates to logging levels, CRUD repository methods, and test coverage for the py_spring_model module. The changes aim to improve logging granularity, enhance method functionality, and provide comprehensive test coverage to ensure code reliability.

Changes Made

1. Logging Improvements:

   • Adjusted logging levels in PySpringModel from info to debug for better control over verbosity in managed session operations:
     • Session commit, close, and instance refresh messages.

2. CRUD Repository Enhancements:

   • Fixed _find_by_query method to correctly unpack and return results.
   • Refined batch deletion methods:
     • delete_all: Uses a SELECT query to fetch entities for deletion.
     • delete_all_by_ids: Handles entity deletion by ID with a bulk query.
   • Improved error handling for cases where no entities are found during delete operations.

3. Test Suite Addition:

   • Added a new test file: tests/test_crud_repository.py.
   • Test cases include:
     • find_by_id, find_all, and find_by_query.
     • delete, delete_by_id, delete_all, and delete_all_by_ids.
     • upsert functionality for both existing and new entities.
   • Utilized an in-memory SQLite database for isolated and repeatable tests.

Benefits

• Improved Debugging: Developers can now use debug-level logs to trace session lifecycle events without cluttering the info log level.
• Enhanced Code Reliability: Fixed and improved CRUD methods to handle edge cases more robustly.
• Comprehensive Testing: New test suite ensures the repository behaves as expected across various scenarios.

How to Test

1. Run the test suite using pytest:
   pytest tests/test_crud_repository.py
2. Confirm all tests pass successfully.
3. Inspect logs during test runs to validate the updated logging levels.
