原标题:How to add an id to an array of object when pushing a new object into the array in node

I have an array called "previousEducation" which initially was empty array, but once I push an object into the array, I want each object that will be push into the array to have an object id. Although from the screenshot I uploaded, the object id was in both (1) and (2) but I don t need the aspect where I circled in (1) I want something inform of the one I named (2) where each object will be having an id follow by the req.body. Is there a way I can push req.body into the array and archive that.

感谢。

我的法典。

  const {receivedEmail, ...myBody} = req.body 
  studentModel.findOneAndUpdate(
    {email: req.body.receivedEmail},
    {$push: {previousEducation:{ _id: new ObjectId(), myBody}}}
  )
  .then((response) => {
    // console.log(response +  JWT );
    res.send({message:  O level Result added successfully , status: true, response});
  })
}```[![The image screenshot][1]][1]
