From 4fa0dd6f6ded6952a628dcd769875839cdae63c3 Mon Sep 17 00:00:00 2001 From: Sharang Parnerkar <30073382+mighty840@users.noreply.github.com> Date: Tue, 7 Apr 2026 19:50:40 +0200 Subject: [PATCH] =?UTF-8?q?refactor(backend/api):=20extract=20VVTService?= =?UTF-8?q?=20(Step=204=20=E2=80=94=20file=205=20of=2018)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit compliance/api/vvt_routes.py (550 LOC) -> 225 LOC thin routes + 475-line VVTService. Covers the organization header, processing activities CRUD, audit log, JSON/CSV export, stats, and version lookups for the Art. 30 DSGVO Verzeichnis. Single-service split: organization + activities + audit + stats all revolve around the same tenant's VVT document, and the existing test suite (tests/test_vvt_routes.py — 768 LOC, tests/test_vvt_tenant_isolation.py — 205 LOC) exercises them together. Module-level helpers (_activity_to_response, _log_audit, _export_csv) stay module-level in compliance.services.vvt_service and are re-exported from compliance.api.vvt_routes so the two test files keep importing from the old path. Pydantic schemas already live in compliance.schemas.vvt from Step 3 — no new schema file needed this round. mypy.ini flips compliance.api.vvt_routes from ignore_errors=True to False. Two SQLAlchemy Column[str] vs str dict-index errors fixed with explicit str() casts on status/business_function in the stats loop.
