Question

Noob问题，但是如何在不声明新const的情况下创建具有相同架构的多个文档。我是否需要为每个键创建一个数组，例如


const newItem = new Item({
  name: ["Blue Shirt", "Green Shirt"],
  image: ["images/image-1.jpg","images/image-2.jpg"],
  price: [30, 20],
  quantity: [5, 10]
});

<------------原码------------->


const newItem = new Item({
  name: "Blue Shirt",
  image: "https://picsum.photos/id/237/200/300",
  price: 30,
  quantity: 5
});

Answer 1

您必须创建一个数据数组。

const newItem = new Item({
  name: "Blue Shirt",
  image: "https://picsum.photos/id/237/200/300",
  price: 30,
  quantity: 5
});

var arr = [newItem]; //Pass array of documents / objects.
Item.insertMany(arr, function(error, docs) {});

或

var arr = ['{
  name: "Blue Shirt",
  image: "https://picsum.photos/id/237/200/300",
  price: 30,
  quantity: 5
}', {
  name: "Blue Shirt",
  image: "https://picsum.photos/id/237/200/300",
  price: 30,
  quantity: 5
}]; //Pass array of documents / objects.

Item.insertMany(arr, function(error, docs) {});
