Over nine months, Pentokami delivered 52 features and 23 bug fixes to the opf/openproject repository, focusing on scalable project phase management, calculated value support, and robust error handling. They engineered persistent export settings, advanced formula editing for custom fields, and automatic recalculation logic to maintain data integrity. Their technical approach emphasized maintainability, with extensive test coverage, code refactoring, and performance optimizations. Using Ruby on Rails, TypeScript, and SQL, Pentokami improved API transparency, UI/UX consistency, and permission management. The work addressed complex business needs, such as multi-project filtering and user-driven time tracking, resulting in a more reliable and flexible product.

Sep 1, 2025September 2025: OpenProject development focused on data integrity, error resilience, and UX improvements across project data exposure, error handling, and API surfaces. Key work includes refining ProjectRepresenter and project schema specs, introducing a CustomValueError model with translation and UI-driven error reporting, and enhancing error handling for calculated and custom fields. API and UI layers were standardized around centralized ErrorContext and polymorphic error types, improving consistency of error messages. Reliability and performance were boosted by a unique database index and migration adjustments, while UI tweaks (error dialog on the Project List, danger icon alignment) improved error visibility. This period also laid groundwork for Scored List features and grouped PDF exports, with ongoing code quality improvements and test coverage.

Aug 1, 2025August 2025 monthly summary for opf/openproject. Delivered two major features to enhance formula customization and API transparency, driving product flexibility and integration readiness. Feature 1 enables using custom fields in formulas with UI updates in the details_form and value editing for calculated fields, accompanied by tests validating formula editing via pattern input. Feature 2 exposes the formula used for calculated custom fields through the API by updating the API schema and representers. No major bugs reported in this period. Impact: improved calculation flexibility, traceability, and easier integration with external systems.

Jun 1, 2025June 2025 highlights focus on scalable phase management, robust filtering, and calculated values, with emphasis on security, performance, and maintainability in opf/openproject. Key outcomes include: (1) Project Phase Filter enhancements with per-project permissions, multi-project handling, and join-optimized queries to improve accuracy and performance across large deployments; (2) Filter subsystem overhaul with Zeitwerk compatibility, sanitized inputs, empty-filter handling, and feature specs to boost reliability and developer velocity; (3) Project Phases API cleanup and permission improvements, including unified query usage, improved view_project_phases permission checks, and API documentation; (4) Calculated Values feature integration, including a feature flag, UI scaffolding, core formula engine and validation, admin UI integration, and translations; and (5) performance and quality improvements across the data model, tests, and memory usage (e.g., replacing collect/each with find_each). These efforts deliver tangible business value: more accurate phase management, safer permission scopes, faster filters in large repos, richer analytics through calculated values, and a cleaner, more maintainable codebase.

Apr 1, 2025In April 2025, the OpenProject repository delivered two major features with strong business value and solid test coverage. First, Export Settings and Saved Queries provides persistent export preferences across dialogs, supports saving/recalling export settings, and integrates with saved queries so unsaved queries don’t carry over settings. The URL/export flow now includes the saved query ID, backed by comprehensive tests for the ExportSetting model and related export logic. Second, the Hover Card UI for Phase Gate Information introduces a reusable Hover Card component in a dedicated namespace, with UI components, CSS for text overflow, robust hover-trigger handling, updated routing/tests, and improved user documentation.
