我的应用程序正在将套接字相关信息保存到socketlist表中。这个想法是，如果带有socket_id的条目不存在，那么在postgres表中创建一个条目。否则什么都不做。代码如下：

await SocketList.findOrCreate({ where: {socket_id : socket_id, active: true}, default: {event_id: event_id, user_id: user_id, server_id: server_id}});

使用sequelizejs 4.42.0。socketlist表是空的，但是上面的代码抛出了下面的错误：

以下是模型定义：

const SocketList = db.define('socketlist', {
    id: {type: Sql.INTEGER,
         primaryKey:true,
         min: 1
    },
    user_id: { type: Sql.INTEGER
    },
    socket_id: {type: Sql.STRING,
                unique: true,
                min: 1
    },
    event_id: {type: Sql.INTEGER,
               min: 1
    },
    server_id: {type: Sql.STRING
    },
    active: {type: Sql.BOOLEAN,
             defaultValue: true,
    },
}....

你必须创建包含id的数据，试试这个怎么样？

id: {
  type: Sql.INTEGER,
  primaryKey:true,
  autoIncrement: true
}
