-- 찜관리 기능을 위한 데이터베이스 스키마

-- 1. 찜 기록 테이블 (public.jjim)
CREATE TABLE IF NOT EXISTS public.jjim (
    id BIGSERIAL PRIMARY KEY,
    user_id UUID NOT NULL,
    market_url TEXT NOT NULL,
    market_name TEXT,
    market_nickname TEXT,
    zzim_count INTEGER DEFAULT 0,
    zzim_type VARCHAR(20) NOT NULL CHECK (zzim_type IN ('my_market', 'mutual')),
    mileage_earned INTEGER DEFAULT 0,
    target_user_id UUID,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    
    CONSTRAINT fk_jjim_user_id FOREIGN KEY (user_id) REFERENCES auth.users(id) ON DELETE CASCADE,
    CONSTRAINT fk_jjim_target_user_id FOREIGN KEY (target_user_id) REFERENCES auth.users(id) ON DELETE SET NULL
);

-- 2. 사용자 마켓 통합 테이블 (public.user_markets) - 찜 관련 필드 추가
CREATE TABLE IF NOT EXISTS public.user_markets (
    id BIGSERIAL PRIMARY KEY,
    user_id UUID NOT NULL,
    
    -- 마켓 목록 (JSONB 배열)
    my_markets JSONB DEFAULT '[]'::jsonb,
    
    -- 찜 통계 필드들 (users 테이블에서 이관)
    my_zzim INTEGER DEFAULT 0,                    -- 받은 찜 총 개수
    zzim_mile INTEGER DEFAULT 0,                  -- 총 마일리지
    available_zzim_mile INTEGER DEFAULT 0,        -- 사용 가능한 마일리지
    today_zzim_count INTEGER DEFAULT 0,           -- 오늘 찜한 개수
    today_zzim_date DATE DEFAULT CURRENT_DATE,    -- 마지막 찜한 날짜
    
    -- 회원등급 (users 테이블과 동기화)
    membership_level VARCHAR(20) DEFAULT 'basic',
    
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    
    CONSTRAINT fk_user_markets_user_id FOREIGN KEY (user_id) REFERENCES auth.users(id) ON DELETE CASCADE,
    CONSTRAINT unique_user_markets_user_id UNIQUE (user_id)
);

-- 3. 회원등급별 찜 제한 테이블 (public.membership_zzim_limits) - 개선
CREATE TABLE IF NOT EXISTS public.membership_zzim_limits (
    id BIGSERIAL PRIMARY KEY,
    membership_level VARCHAR(20) NOT NULL UNIQUE,
    
    -- 찜 제한 설정
    daily_zzim_limit INTEGER DEFAULT 50,         -- 일일 찜 제한
    max_zzim_mileage INTEGER DEFAULT 500,        -- 최대 마일리지 보유량
    mileage_per_zzim INTEGER DEFAULT 1,          -- 찜당 마일리지
    
    -- 추가 제한 설정
    max_markets INTEGER DEFAULT 5,               -- 최대 등록 가능한 마켓 수
    mutual_zzim_enabled BOOLEAN DEFAULT TRUE,    -- 품앗이 기능 사용 가능 여부
    background_zzim_enabled BOOLEAN DEFAULT FALSE, -- 백그라운드 찜 기능 사용 가능 여부
    
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);

-- 4. 기본 회원등급 데이터 삽입
INSERT INTO public.membership_zzim_limits (membership_level, daily_zzim_limit, max_zzim_mileage, mileage_per_zzim, max_markets, mutual_zzim_enabled, background_zzim_enabled) 
VALUES 
    ('basic', 50, 500, 1, 3, TRUE, FALSE),
    ('premium', 100, 1000, 1, 10, TRUE, TRUE),
    ('vip', 200, 2000, 1, 20, TRUE, TRUE)
ON CONFLICT (membership_level) DO UPDATE SET
    daily_zzim_limit = EXCLUDED.daily_zzim_limit,
    max_zzim_mileage = EXCLUDED.max_zzim_mileage,
    mileage_per_zzim = EXCLUDED.mileage_per_zzim,
    max_markets = EXCLUDED.max_markets,
    mutual_zzim_enabled = EXCLUDED.mutual_zzim_enabled,
    background_zzim_enabled = EXCLUDED.background_zzim_enabled,
    updated_at = NOW();

-- 5. 마켓 데이터 구조 예시 (my_markets JSONB 필드 내용)
/*
my_markets JSONB 예시:
[
  {
    "market_url": "https://smartstore.naver.com/example",
    "market_name": "예시 마켓",
    "market_nickname": "내 마켓",
    "is_visible": true,                    -- 다른 사람에게 노출 여부
    "for_zzim": true,                      -- 내 마켓 찜하기 대상 여부
    "for_mutual_zzim": true,               -- 품앗이 대상 여부 (새로 추가)
    "zzim_received_count": 0,              -- 받은 찜 개수
    "created_at": "2024-01-01T00:00:00Z",
    "updated_at": "2024-01-01T00:00:00Z"
  }
]
*/

-- 6. 인덱스 생성
CREATE INDEX IF NOT EXISTS idx_jjim_user_id ON public.jjim(user_id);
CREATE INDEX IF NOT EXISTS idx_jjim_target_user_id ON public.jjim(target_user_id);
CREATE INDEX IF NOT EXISTS idx_jjim_created_at ON public.jjim(created_at);
CREATE INDEX IF NOT EXISTS idx_jjim_zzim_type ON public.jjim(zzim_type);

CREATE INDEX IF NOT EXISTS idx_user_markets_user_id ON public.user_markets(user_id);
CREATE INDEX IF NOT EXISTS idx_user_markets_membership_level ON public.user_markets(membership_level);
CREATE INDEX IF NOT EXISTS idx_user_markets_today_zzim_date ON public.user_markets(today_zzim_date);

-- 7. RLS (Row Level Security) 정책 설정
-- user_markets 테이블: 품앗이를 위해 읽기는 모든 사용자에게 허용, 쓰기는 본인만
ALTER TABLE public.user_markets ENABLE ROW LEVEL SECURITY;

-- 본인 데이터 읽기/쓰기 허용
CREATE POLICY "Users can view and edit their own user_markets data" ON public.user_markets
    FOR ALL USING (auth.uid() = user_id);

-- 품앗이를 위한 다른 사용자 데이터 읽기 허용 (민감하지 않은 정보만)
CREATE POLICY "Users can view others user_markets for mutual zzim" ON public.user_markets
    FOR SELECT USING (true);

-- jjim 테이블: 본인이 한 찜 기록만 조회/수정 가능
ALTER TABLE public.jjim ENABLE ROW LEVEL SECURITY;

CREATE POLICY "Users can view and edit their own jjim records" ON public.jjim
    FOR ALL USING (auth.uid() = user_id);

-- membership_zzim_limits 테이블: 모든 사용자가 읽기 가능
ALTER TABLE public.membership_zzim_limits ENABLE ROW LEVEL SECURITY;

CREATE POLICY "All users can view membership limits" ON public.membership_zzim_limits
    FOR SELECT USING (true);

-- 8. 데이터 마이그레이션 함수 (users 테이블에서 user_markets로 찜 데이터 이관)
CREATE OR REPLACE FUNCTION migrate_zzim_data_to_user_markets()
RETURNS void AS $$
BEGIN
    -- users 테이블의 찜 관련 데이터를 user_markets로 이관
    INSERT INTO public.user_markets (
        user_id,

        updated_at = NOW();
        
    RAISE NOTICE 'Zzim data migration completed';

-- 9. 트리거 함수: user_markets와 users 테이블 동기화
CREATE OR REPLACE FUNCTION sync_user_markets_to_users()
RETURNS TRIGGER AS $$
BEGIN
    -- user_markets 테이블의 변경사항을 users 테이블에 반영
