Docker Image bauen und veroeffentlichen / build-and-push (push) Successful in 2m15s
The ApiCore sync failed with "Unique constraint failed on the constraint:
harvests_year_type_key" as soon as ApiCore had two harvests of the same
honey type in one year, which is normal (several extractions per season).
Every bottling of that harvest was then skipped too.
- Drop the (year, type) unique index. The slug is now the only unique,
public identifier: /ernten/<slug>, e.g. bluetenhonig-2026, then
bluetenhonig-2026-07-14 for a further harvest of the same type.
- New Harvest.apicoreHarvestId as the sync key, backfilled from the old
"apicore-<id>" slugs; the sync gives those rows a readable slug.
- Slugs are generated by one shared slugify() that normalizes Unicode
(decomposed umlauts) and writes out umlauts. The migration repairs
manual slugs created by the old umlaut bug ("fr-htracht-2026").
- Slug collisions are resolved by the database unique index, so parallel
writers cannot produce duplicates; known slugs are skipped up front to
keep the logs free of handled P2002 errors.
- Old URLs /ernten/<year>/<type> answer with 308 to the new address.
