如何在示例文档中填充"组件":

  {
    "__v": 1,
    "_id": "5252875356f64d6d28000001",
    "pages": [
      {
        "__v": 1,
        "_id": "5252875a56f64d6d28000002",
        "page": {
          "components": [
            "525287a01877a68528000001"
          ]
        }
      }
    ],
    "author": "Book Author",
    "title": "Book Title"
  }

这是我的JS,我通过Mongoose获取文档:

  Project.findById(id).populate('pages').exec(function(err, project) {
    res.json(project);
  });
