如何从猫鼬的嵌套数组中拉出对象

Question

我无法删除集合中的对象表单数组。我正在使用猫鼬和Nest.js

我正在尝试从数组beers中删除对象（啤酒）。

我也尝试过findOneAndUpdate 或this.userModel.update({user:user}, {$pull:{'beers.id':id});

这是我的收藏

We brewed up a wort with a light caramel note and some toasty biscuit flavour, and hopped it with Amarillo and Centennial for a citrusy bitterness. Everything else is down to the yeast. Pilsner yeast ferments with no fruity esters or spicy phenols, although it can add a hint of butterscotch.",

这是我删除对象表格数组的功能

  async removeBeerFromUser(user, id) {
    this.userModel.update({user:user}, {$pull:{beers:{id:id}}, (err, val) => {
      console.log(val);
    });
  }

但无能为力

没有错误。控制台日志返回空啤酒阵列。但是当我从邮递员那里检查它时，它并不为空
