📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal:

The session aimed to enhance the architecture of a Flask application by refactoring key components, improving code modularity, and resolving structural issues.

Key Activities:

  • Open-Source Tools Exploration: Reviewed open-source tools for knowledge management in RAG systems, focusing on document ingestion and integration with vector databases.
  • Flask Refactoring: Refactored the main.py to integrate OAuth, Firebase, and session management, ensuring a clean and testable architecture.
  • Feedback Route Implementation: Developed a robust feedback submission route with defensive programming, centralized logging, and explicit error handling.
  • Function and Module Refinement: Refactored the submit_answer function, enhancing logic, logging, and input validation. Refined the routes/exercises.py module for better organization.
  • Teacher Time Request Logic Consolidation: Merged duplicate logic into a single, efficient routes/teachers.py file, focusing on validation and Firestore handling.
  • Script Enhancement: Improved a Python script for CSV to MySQL import, emphasizing error handling and configurability.
  • Circular Import Resolution: Addressed a circular import issue in the Flask application by using current_app.

Achievements:

  • Successfully refactored key components of the Flask application, improving maintainability and robustness.
  • Resolved structural issues such as circular imports, ensuring smoother application operation.
  • Enhanced error handling and logging across various modules.

Pending Tasks:

  • Further testing of the refactored components in a production environment to ensure stability.
  • Continuous monitoring for any emerging issues related to the new architecture.
