Backend: Zapisnici list

Backend task for the Zapisnici list and the PDF download (GET /drivepark/records, GET /drivepark/records/{recordId}/pdf/{stage}) – check the API spec and DB structure, compute the status, search and sort, stream the stored PDFs, implement, and verify against the spec.

Docs: Zapisnici list Spec: GET /drivepark/records (getDriveParkRecords), GET /drivepark/records/{recordId}/pdf/{stage} (downloadDriveParkRecordPdf), DriveParkRecord, DriveParkRecordStatus, DriveParkRecordStage in api-docs/openapi.yaml DB: DriveParkRecords in api/database/pending_schema.sql (-- DRIVE PARK --)

1. Double check API spec and DB structure

• Every list column has a field in DriveParkRecord: Vozilo (vehicleBrandCode, vehicleName, vehiclePlate), Korisnik (fullName, company), Razdoblje (usageFrom – usageTo, the record’s own Rok korištenja), Status (status).
• Status is computed (Draft / Preuzeto / Vraćeno from PickupCompletedAt / ReturnCompletedAt), not stored. Check the button table in the docs can be built from status alone: Draft → open pickup form; Preuzeto → pickup view + pickup PDF + open return form; Vraćeno → both views + both PDFs. (The spec and Figma show only “Download PDF” for completed records; the docs add “Otvori zapisnik …” to open the views. The client decides.)
• Sorting and page size: not specified (docs comment: “Recommended: 10 records per page, sorted by Razdoblje Od, newest first”). The spec sorts by usageFrom descending, nulls first. Confirm; the frontend sends perPage=10.
• Search: vehicle (name, plate) and user (fullName, company). Check the docs agree (“Pretraži po vozilu ili korisniku”).
• Two PDFs per record, one per stage. The PDF layout is not specified yet.
• Roles and permissions: drivepark.access.
• DB: IX_DriveParkRecords_UsageFrom for the sort.

2. Implementation

• Roles and permissions: require drivepark.access → 403.
• List: one count query and one page query (OFFSET / FETCH), joined with Vehicles for vehicleBrandCode, vehicleName, vehiclePlate (no DeletedAt / archived filter); search with LIKE on Vehicles.Name, Vehicles.Plate, FullName and Company; status as a CASE expression.
• PDF: load the record; the stage’s *PdfBlob is null (stage not completed) → 404; otherwise stream the blob as application/pdf with Content-Disposition (e.g. Zapisnik-o-preuzimanju-ZG-123-AA.pdf).

3. Verify implementation against spec

• Routes, query parameters and response shapes match getDriveParkRecords and downloadDriveParkRecordPdf.
• 401 / 403 / 404 / 500 can be produced; no undocumented ones.
• One record of each status → draft, picked-up, returned.
• Search by part of the plate and by part of the company name both find the record.
• Return PDF of a Preuzeto record → 404; pickup PDF of a Draft → 404.

Done when

The Zapisnici list shows every record with its status and the right buttons, and the PDFs can be downloaded.
