I have an array of object like this return to mongoDB server.

[{"key":"demo_date","value":["2022-12-11T08:00:00.000Z","2022-12-12T08:00:00.000Z"...]}]

And query object like this

queryObj = {
      $and: [
        { deleted: false },
        {$or: []}
      ]
};

And I use this query object for the find method to get data from collection.

let data = await this.demoModel.find(queryObj, (err: Error) => {})

My question is how can I modify the queryObj such that the result would find all data with demo_dates as key and the value is in value array?

The record sample are like this

{
  _id: ObjectId('574168516'),
  demoLayer1: {
      demo_date: '2022-08-18T14:20:00.000Z',
      decoyDate: '2022-08-19T14:20:00.000Z',
  }
}

CodePudding user response：

You can use the $in operator to match a value within an array of possible values:

The $in operator selects the documents where the value of a field equals any value in the specified array.

db.collection.find({
  $and: [
    {
      //deleted: false,
      "demoLayer1.demo_date": {
        $in: [
          "2022-12-11T08:00:00.000Z",
          "2022-12-12T08:00:00.000Z",
          "2022-08-18T14:20:00.000Z"
        ]
      }
    }
  ]
})
