Description

Generating an invoice from about 100 or more time entries returned a 500 on PostgreSQL: value too long for type character varying(500). A grouped line stores every entry id joined with commas in invoice_items.time_entry_ids, and grouped is the default. SQLite doesn't enforce the length, so only PostgreSQL deployments hit it.

The column is now Text, with a migration.

On PostgreSQL 16, an invoice from 160 entries returned 500 before, and after changing the column it created the grouped line. flask db upgrade and downgrade both run on the new migration.

Type of change

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would change existing behavior)
• Documentation update
• Refactor (no functional change)

Checklist

• My code follows the project's style guidelines (Black, flake8).
• I have added/updated tests for my changes. (The test database is SQLite, which doesn't enforce the length, so a test wouldn't fail without the change.)
• All tests pass locally (e.g. pytest). (Not run in full, too heavy for this laptop.)
• I have updated the documentation if needed.
• For user-facing changes, I have added an entry to the Unreleased section of CHANGELOG.md.
