[jjmata]

Summary

This PR addresses some final/dangling unresolved code review comments from PR #267.

Changes

1. Fix down migration constraints in drop_was_merged_from_transactions.rb

   • Add null: false, default: false to match original column definition
   • Ensures proper rollback compatibility

2. Improve exception handling in maps_helper.rb

   • Replace bare rescue with rescue StandardError => e
   • Add logging for better debugging

Notes

• Most CodeRabbit comments were already addressed in the original PR Simplefin enhancements v2 #267
• These are the remaining quality improvements for code consistency
• Changes follow Rails/Ruby best practices

Summary by CodeRabbit

• Bug Fixes

  • Enhanced error handling with improved logging for better diagnostics and troubleshooting

• Chores

  • Updated database migration with refined constraints for data integrity

Walkthrough

Two focused improvements to error handling and database constraints: enhanced exception logging in the maps helper's duplicate flag computation, and explicit null/default constraints on the was_merged column in the down migration for better data integrity.

Changes

Cohort / File(s)	Summary
Error Handling & Logging app/controllers/concerns/simplefin_items/maps_helper.rb	compute_duplicate_only_flag rescue clause now explicitly catches StandardError and logs warnings with exception class and message before returning false
Migration Constraints db/migrate/20251103185320_drop_was_merged_from_transactions.rb	Down migration's was_merged column addition now enforces null: false constraint with default: false, improving data integrity

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Verify logging integration and message format are consistent with codebase conventions
• Confirm migration constraint (null: false, default: false) doesn't conflict with existing data or upstream migrations

Poem

🐰 Errors now speak with clarity clear,
Logs will whisper what we need to hear,
Database walls grow tall and strong,
Constraints ensure nothing goes wrong! 🛡️

90-92: Excellent improvement to exception handling!

The change from bare rescue to rescue StandardError => e with explicit logging follows Rails best practices and significantly improves observability for debugging.

db/migrate/20251103185320_drop_was_merged_from_transactions.rb (1)

10-12: Good addition of constraints for rollback compatibility!

Adding null: false, default: false ensures the down migration properly recreates the column with its original definition, which is essential for safe rollback operations and data integrity.
