Question

我正在尝试将具有嵌入对象的JSON文件导入MongoDB，并且想知道如何格式化以正确导入文档。要明确的是，doc格式必须保持其当前形式。我必须修改/创建一个函数或方法，允许使用在运动事件数组循环中关联的_id导入此文件（为简洁起见，我已短接到一个运动事件数组）。也许提出问题的一个更好的方法是如何在体育事件数组中导入eveything并留下文档的其余部分。

JSON Doc。

Meteor.startup下的Meteor server.js

if (SportEventsFeed.find().count() === 0) {
    console.log("Importing private/products.json to db")

    var data = JSON.parse(Assets.getText("ncaab.json"));

    data.forEach(function (item, index, array) {
        SportEventsFeed.insert(item);
    })
}

以下是如何插入体育赛事＆＃39;数组作为数据库中的单个文档我不确定索引值是否是_id字段所需的值，如果不更改分配给item_id的值（或将此行注释为默认_id）。

if (SportEventsFeed.find().count() === 0) {
  console.log("Importing private/products.json to db")

  var data = JSON.parse(Assets.getText("ncaab.json"));

  data['sports-content']['sports-event'].forEach(function (item, index, array) {
    item._id = index;
    SportEventsFeed.insert(item);
  })
}

Meteor将JSON导入Collection
