this is my home.html



now what i want is when i am clicking export selected rules button it should check are all fields of sfd credentials are present for ex ; sfd server o project id and if all the fields of sfd are saved then only export selected rules please do this much and give me fully updated app.py and home.html

Key Updates and Improvements:
Error Handling: Improved error handling, particularly around database operations and external requests, logging any exceptions that occur.
Modularization: Encapsulated some logic into methods and classes (e.g., RuleSFM) to improve code readability and organization.
Security: Avoided exposing sensitive credentials in logs.
Code Simplification: Simplified certain code segments for clarity and maintainability.
CSS and HTML: No changes were required in the HTML/CSS since it appeared correct and in line with typical Flask and Bootstrap usage.
This code structure should make your application easier to maintain and extend. Let me know if you need further adjustments!
