我一直在用一个对象ID数组保存一个对象。我正在将node.js与restify和猫鼬一起使用。
我有很多服装选择的服装要求：

它保持循环，但记录保存在数据库中
我认为这与链式诺言有关，但是我找不到解决办法。

我是这样的，我返回了最后的承诺，并将print放入.then
application.post('/outfit-choices', (req, resp, next) => {
OutfitRequest.findById(req.body.outfitRequest)
.then(outfitRequest => {
const outfitChoice = new OutfitChoice(req.body);
outfitChoice.save()
.then(outfitChoice => {
outfitRequest.outfitChoices.push(outfitChoice._id);
return outfitRequest.save()
})
.then(this.render(resp, next))
.catch(next);
})
.catch(next);
});
