在.get

Question

我有node7和sequelize 4.2。

我试图使用model.get（{plain：true}），但它给了我一个错误：

TypeError: instance.get is not a function

代码：

                        game.model.save().then(() => {
                            currentGames[game.model.id] = game;

                            callback(null, {
                                roundInfo: game.model.get({ plain: true })   });
                        }, err => callback(err));

＆＃34;游戏＆＃34;以前在对象中找到：

for(let currentGameKey in currentGames) {
        if(!currentGames.hasOwnProperty(currentGameKey)) continue;
        if(gameId == currentGameKey) {
            continuation(currentGames[currentGameKey], false);
            break;
        }
    }

它可能是什么？
