-- Bug 22a audit: kn-API payload vs domrf_kn_objects / domrf_kn_flats mapping.
|
|
--
|
|
-- FINDINGS (payload audit on obj_id=65136, all 1516 objects in kn_object_place_66,
|
|
-- snapshot 2026-05-05):
|
|
--
|
|
-- Object-level fields (/kn/object list endpoint):
|
|
-- wallType — 0/1516 objects have key in payload → API never returns it.
|
|
-- aiDescription mentions wall material as free text but no
|
|
-- clean extraction without NLP. No backfill possible.
|
|
-- energyEff — 0/1516 objects have key in payload → API never returns it.
|
|
-- No source for backfill.
|
|
-- objClass — 0/1516 objects have key in payload → API never returns it.
|
|
-- FIXED in migration 106 (extract from aiDescription) + SF#15
|
|
-- scraper fix. Coverage after 106: 1806/4548 filled.
|
|
--
|
|
-- Flat-level fields (/portal-kn/api/sales/portal/table endpoint):
|
|
-- number → flat_number: mapped in _norm_flat() via _g(row, "number", "flatNumber").
|
|
-- Confirmed present in payload for active-sale objects.
|
|
-- livingArea → living_area: mapped in _norm_flat() via _g(row, "livingArea").
|
|
-- Confirmed present in payload for active-sale objects.
|
|
--
|
|
-- Root cause for 0% flat_number/living_area in domrf_kn_flats:
|
|
-- UPSERT_FLAT_SQL ON CONFLICT (id, snapshot_date) DO UPDATE SET did NOT include
|
|
-- flat_number, living_area, is_studio, total_area, rooms, floor, num_floors.
|
|
-- Rows first inserted from older scrape (hash-id, no direct numeric id → NULL fields)
|
|
-- were never updated on subsequent scrapes.
|
|
-- FIX: domrf_kn.py UPSERT_FLAT_SQL now uses COALESCE for these fields.
|
|
-- Coverage will improve on next scrape run (no stored flat-level raw → no backfill).
|
|
--
|
|
-- UPSERT_OBJECT_SQL ON CONFLICT also missed wall_type / energy_eff updates.
|
|
-- FIX: added COALESCE for wall_type and energy_eff in ON CONFLICT clause.
|
|
--
|
|
-- All columns already exist — no DDL changes needed. This migration is a no-op
|
|
-- idempotent guard; the real fix is in backend/app/services/scrapers/domrf_kn.py.
|
|
--
|
|
-- Idempotent: safe to re-run.
