-- 147_admin_create_stop_rpcs.sql
-- SECURITY DEFINER RPCs for stop creation.
--
-- The stops table has RLS enabled with `block_stops_mutations`
-- (FOR INSERT WITH CHECK (false)) — direct REST inserts from
-- server actions are blocked. Previously `createStop` /
-- `createStopsBatch` in src/actions/stops/ relied on
-- SUPABASE_SERVICE_ROLE_KEY to bypass RLS, but:
--   1. In production environments the env var may be unset,
--      which silently downgrades the apikey header to anon and
--      triggers 42501.
--   2. createStopsBatch was hardcoded to NEXT_PUBLIC_SUPABASE_ANON_KEY,
--      which always fails with RLS enabled.
--
-- These RPCs run as the function owner (bypasses RLS) and accept
-- p_brand_id for explicit brand scoping. The application layer
-- (server actions) still validates the caller has can_manage_stops
-- via getAdminUser() before invoking the RPC.
--
-- Table schema (relevant columns):
--   id          UUID          PK
--   brand_id    UUID          FK brands
--   city        TEXT
--   state       TEXT
--   location    TEXT
--   date        TIMESTAMPTZ
--   time        TEXT          -- free-form ("8:00 AM – 2:00 PM")
--   address     TEXT
--   zip         TEXT
--   cutoff_time TIMESTAMPTZ   -- accepts ISO datetime OR "HH:MM"
--   slug        TEXT
--   active      BOOLEAN
--   status      TEXT          -- 'draft' | 'active' | ...

BEGIN;

-- ── 1. admin_create_stop ───────────────────────────────────────────────────
-- Inserts a single stop. Slug is derived from city + date; if a stop with
-- the same slug already exists for the brand, a numeric suffix is appended.
--
-- Robust type handling:
--   * p_date TEXT  -> cast to TIMESTAMPTZ; NULLIF handles empty string
--   * p_cutoff_time TEXT  -> accepts full ISO datetime ("2025-01-01T08:00")
--     OR a time-only value ("08:00" / "08:00:00") which is combined with
--     p_date to form a TIMESTAMPTZ. NULLIF handles empty string.
--   * p_time TEXT is passed through as-is (the column is free-form text).

-- ── 3. Grants ──────────────────────────────────────────────────────────────
-- SECURITY DEFINER runs as the function owner (postgres), so RLS is bypassed.
-- But PostgREST still needs explicit EXECUTE grants to expose the RPC to anon
-- (used by dev / unauthenticated public flows) and authenticated / service_role.

GRANT EXECUTE ON FUNCTION public.admin_create_stop(
  UUID, TEXT, TEXT, TEXT, TEXT, TEXT, TEXT, TEXT, TEXT, BOOLEAN

-- ── 4. Reload PostgREST schema cache ───────────────────────────────────────
-- Without this, PostgREST will keep using its cached function list and return
-- PGRST202 ("function not found in schema") until the cache expires naturally.
-- Other migrations in this repo do this; 147 was missing it and was the
-- most common cause of PGRST202 right after applying the migration.

NOTIFY pgrst, 'reload schema';
