Re-pushing an edited route to Wahoo now updates the existing remote route via PUT against the stored remote_id instead of POSTing a new copy. external_id drops the version suffix and identifies the logical route. sync_pushes is keyed by (user, route, provider) and tracks last_pushed_version for the "local newer" UI state.

-- Data migration for the wahoo-route-update change.

|
|
-- Why this lives outside drizzle-kit push:
|
|
-- `drizzle-kit push --force` will happily DROP `route_version` and try to add
|
|
-- the new unique index on (user_id, route_id, provider), but if any user has
|
|
-- successfully pushed multiple versions of a route the duplicate-row check on
|
|
-- the new unique would fail. We need to backfill `last_pushed_version` and
|
|
-- collapse rows BEFORE drizzle-kit reshapes the table.
|
|
--
|
|
-- Idempotent: safe to run before every deploy until the old `route_version`
|
|
-- column is gone. Once `route_version` is dropped (i.e. drizzle-kit push has
|
|
-- run after this script), the body is a no-op.
