-- ============================================================
-- ViGent 手机号登录迁移脚本
-- 用于将 email 字段改为 phone 字段
-- 
-- 执行方式（任选一种）：
-- 1. Supabase Studio: 打开 https://supabase.hbyrkj.top -> SQL Editor -> 粘贴执行
-- 2. Docker 命令: docker exec -i supabase-db psql -U postgres < migrate_to_phone.sql
-- ============================================================

-- 注意：此脚本会删除现有的用户数据！
-- 如需保留数据，请先备份

-- 1. 删除依赖表（有外键约束）
DROP TABLE IF EXISTS user_sessions CASCADE;
DROP TABLE IF EXISTS social_accounts CASCADE;

-- 2. 删除用户表
DROP TABLE IF EXISTS users CASCADE;

-- 3. 重新创建 users 表（使用 phone 字段）
CREATE TABLE users (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    phone TEXT UNIQUE NOT NULL,
    password_hash TEXT NOT NULL,
    username TEXT,
    role TEXT DEFAULT 'pending' CHECK (role IN ('pending', 'user', 'admin')),
    is_active BOOLEAN DEFAULT FALSE,
    expires_at TIMESTAMP WITH TIME ZONE,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    updated_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);

-- 4. 重新创建 user_sessions 表
CREATE TABLE user_sessions (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    user_id UUID REFERENCES users(id) ON DELETE CASCADE UNIQUE,
    session_token TEXT UNIQUE NOT NULL,
    device_info TEXT,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);

-- 5. 重新创建 social_accounts 表
CREATE TABLE social_accounts (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    user_id UUID REFERENCES users(id) ON DELETE CASCADE,
    platform TEXT NOT NULL CHECK (platform IN ('bilibili', 'douyin', 'xiaohongshu')),
    logged_in BOOLEAN DEFAULT FALSE,
    created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW(),
    UNIQUE(user_id, platform)
);

-- 6. 创建索引
CREATE INDEX idx_users_phone ON users(phone);
CREATE INDEX idx_sessions_user_id ON user_sessions(user_id);
CREATE INDEX idx_social_user_platform ON social_accounts(user_id, platform);

-- 7. 启用 RLS
ALTER TABLE users ENABLE ROW LEVEL SECURITY;
ALTER TABLE user_sessions ENABLE ROW LEVEL SECURITY;
ALTER TABLE social_accounts ENABLE ROW LEVEL SECURITY;

-- 8. 创建 RLS 策略
CREATE POLICY "Users can view own profile" ON users
    FOR SELECT USING (auth.uid()::text = id::text);

CREATE POLICY "Users can access own sessions" ON user_sessions
    FOR ALL USING (user_id::text = auth.uid()::text);

CREATE POLICY "Users can access own social accounts" ON social_accounts
    FOR ALL USING (user_id::text = auth.uid()::text);

-- 9. 更新时间触发器
CREATE OR REPLACE FUNCTION update_updated_at()
RETURNS TRIGGER AS $$
BEGIN
    NEW.updated_at = NOW();
    RETURN NEW;
END;
$$ LANGUAGE plpgsql;

DROP TRIGGER IF EXISTS users_updated_at ON users;
CREATE TRIGGER users_updated_at
    BEFORE UPDATE ON users
    FOR EACH ROW
    EXECUTE FUNCTION update_updated_at();

-- 完成！
