node.js - 通过(sails js)水线将值推送到mongodb数据库数组中

Question

Node js， sails js，水线。插入后我需要将值更新(或推送)到以下架构中

我正在使用带有水线和 mongodb 的sailsjs。

{
"countries": {
"states": [
{
"statename": "state",
"districts": [
{
"distname": "district",
"cities": [
{
"cityname": "Hyderabad",
"places": [
                {
                  "placename": "hitechcity"
                }
              ]

          }
        ]
      }
    ]
  }
]
}
}

我需要知道如何更新它更新后我需要这样的东西

{
"countries": {
"states": [
{
"statename": "state",
"districts": [
{
"distname": "district",
"cities": [
{
"cityname": "Hyderabad",

              "places": [
                {
                  "placename": "hitechcity"
                },
                {
                  "placename": "someother place"
                }
              ]

          }
        ]
      }
    ]
  }
]
}
}

请有人帮助我。

好问题!你会想要使用 addToCollection():

await User.addToCollection(23, 'roles')
.members([3, 5, 6]);

在我的手机上完成，很抱歉有任何错别字:)
