流星。MongoDB插入错误: TypeError: keypath.split不是函数。(在'keypath.split('.')‘中，'keypath.split’未定义)

Question

Foo是我的MongoDB collection。在这里，我只有一个document：

{
  0: {code: "basic", caption: "basic", points: 100},
  1: {code: "gold", caption: "gold", points: 200},
  2: {code: "platinum", caption: "platinum", points: 300},
  3: {code: "diamond", caption: "diamond", points: 400}, 
  id: "PnpbhFi8m7NqZXRr6"
}

当我尝试upsert时，我会收到以下错误：

TypeError: keypath.split is not a function. (In 'keypath.split('.')', 'keypath.split' is undefined)

这是我的密码：

const data = [
  {
    "code": "basic",
    "caption": "basic",
    "points": 100
  },
  {
    "code": "gold",
    "caption": "gold",
    "points": 200
  },
  {
    "code": "platinum",
    "caption": "platinum",
    "points": 300
  },
  {
    "code": "diamond",
    "caption": "diamond",
    "points": 400
  }
];

const doc = Foo.findOne();
Foo.upsert(doc._id, { $set: data });

我的错误在哪里？

Answer 1

你用错了$set。您必须将对象传递给$set

Foo.update(doc._id, {
  $set: {
    4: data[0],
    5: data[1],
    6: data[2],
    7: data[3],
  }
});

此外，您也不必使用upsert。来自流星博士关于upsert的报道

修改集合中的一个或多个文档，如果没有找到匹配的文档，则插入一个文档。

但是您的文档是存在的，所以不需要upsert，请使用update
