Mar 1, 2025

March 2025 (2025-03) monthly summary for Bostads-AB-Mimer repositories focused on delivering business value through data-flow improvements, model alignment, and test quality enhancements across onecore-core and onecore. Key efforts reduced latency, streamlined data paths, and prepared the codebase for future tenant-management features, while tightening test integrity and ensuring accurate user-facing data. Key features delivered and major changes: - Maintenance Unit Retrieval Optimization: Introduced adapter method getLeasesForContactCode to fetch leases by contact code, removing the redundant getContactByContactCode call and improving data-fetch efficiency. Associated work modernizes the maintenance-unit data path. (Commits: eb32cb1afa35c9972fe64a8c3378d39a665f61af, MIM-413 (#261)). - WorkOrder LastChanged alignment and TenantFactory enhancements: Normalized LastChanged naming across WorkOrder types and adapters, and augmented TenantFactory with isAboutToLeave for future tenant-management features; accompanying test factory updates to reflect changes. (Commits: c58de4006cd703f92624dd37b3045f4acb82a7f9, 727e52c1df13dceaee3bff858afe1d4b8bca6f8d, 75c104fa0193d2401ceded3b097a7e9442805851). - Pet status display fix on Mina Sidor: Stabilized pet status by transforming odooWorkOrder.pet into Ja/Nej for accurate user-facing information. (Commit: 620240a6d041f02dd67704ab7a80ae9f68f6177d). - Contact management: specialAttention flag: Added a new boolean field specialAttention to the Contact interface to flag contacts requiring special attention. (Commit: 0df23489e9a69408ae71159b672a7b090ab5f347). - Test factory type alignment: Updated test factories to reflect new/changed types for tenant and work order objects, ensuring test suite integrity amidst model changes. (Commit: 439b4a0e7a1de288f1ccefd931385df22fedae4e). Overall impact and business value: - Reduced latency and improved data consistency for core maintenance workflows by replacing pnr-based retrieval with direct contact-code lookups. - Strengthened code quality and future readiness for tenant-management features through naming alignment and enhanced factory/test support. - Improved user-facing accuracy on Mina Sidor and better targeting capabilities for high-priority contacts via new specialAttention flag. - Demonstrated strong collaboration and code quality practices across repos with concise, well-documented commits and tests.
