I am using a mongoose. I have a record of users. I am making the notification feature. I have an array of objects for notification fields. I want to update the notification status (Here the field "readed") for id(1672147216504,1672201273818) from false to true of any particular user. Here id means the time field in the object. I have read the document, but it's not updated when I update the field.

I don't know where I am making a mistake.

Can anyone tell me how I can do that? I have tried the following code.

const notiticationIds = [1672147216504, 1672201273818]
const data = await user.findOneAndUpdate(
    { _id: userid, 'notifications.notiticationId': notiticationIds }, {
    '$set': {
        'notifications.$.readed': 'true',
    }
})

CodePudding user response：

One option is to use $[<identifier>] in order to choose the specific items to update inside the array. If you want to get back the document after the update (this is not the default), use returnNewDocument: true

const data = await user.findOneAndUpdate(
  {_id: userid,
   notification : {
    $elemMatch: {
      notiticationId: {$in: ["1672147216504", "1672201273818"]}
    }
  }},
  {$set: {"notification.$[item].readed": true}},
  {
    arrayFilters: [{"item.notiticationId": {$in: ["1672147216504", "1672201273818"]}}],
    returnNewDocument: true
  }
)

See how it works on the playground example
