-- Migration for Advanced Tagging System

-- 1. Rename existing 'tasting_tags' to 'tasting_buddies'
-- This table currently stores which buddies are part of a tasting.
DO $$ 
BEGIN
    IF EXISTS (SELECT FROM pg_tables WHERE schemaname = 'public' AND tablename  = 'tasting_tags') THEN
        ALTER TABLE tasting_tags RENAME TO tasting_buddies;
    END IF;
END $$;

-- 2. Create 'tags' table
CREATE TYPE tag_category AS ENUM ('nose', 'taste', 'finish', 'texture');

CREATE TABLE IF NOT EXISTS tags (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    name TEXT NOT NULL,
    category tag_category NOT NULL,
    is_system_default BOOLEAN DEFAULT false,
    popularity_score INTEGER DEFAULT 3, -- 1 to 5
    created_by UUID REFERENCES profiles(id) ON DELETE CASCADE,
    UNIQUE(name, category)
);

-- 3. Create new 'tasting_tags' junction table (for aroma tags)
CREATE TABLE IF NOT EXISTS tasting_tags (
    tasting_id UUID REFERENCES tastings(id) ON DELETE CASCADE NOT NULL,
    tag_id UUID REFERENCES tags(id) ON DELETE CASCADE NOT NULL,
    user_id UUID REFERENCES profiles(id) ON DELETE CASCADE NOT NULL,
    PRIMARY KEY (tasting_id, tag_id)
);

-- 4. Enable RLS
ALTER TABLE tags ENABLE ROW LEVEL SECURITY;
ALTER TABLE tasting_tags ENABLE ROW LEVEL SECURITY;

-- 5. Policies for 'tags'
-- Everyone can read system default tags and their own custom tags
DROP POLICY IF EXISTS "tags_select_policy" ON tags;
CREATE POLICY "tags_select_policy" ON tags
    FOR SELECT USING (
        is_system_default = true OR 
        (SELECT auth.uid()) = created_by OR
        EXISTS (SELECT 1 FROM admin_users WHERE user_id = (SELECT auth.uid()))
    );

-- Users can insert their own custom tags
DROP POLICY IF EXISTS "tags_insert_policy" ON tags;
CREATE POLICY "tags_insert_policy" ON tags
    FOR INSERT WITH CHECK (
        (SELECT auth.uid()) = created_by
    );

-- 6. Policies for 'tasting_tags' (junction)
DROP POLICY IF EXISTS "tasting_tags_owner_policy" ON tasting_tags;
CREATE POLICY "tasting_tags_owner_policy" ON tasting_tags
    FOR ALL USING ((SELECT auth.uid()) = user_id);

-- 7. Insert Master List of System Tags
INSERT INTO tags (name, category, is_system_default) VALUES
