How to update objects in document's array (mongodb)

Question

Assume I have the following document:

 { name: 'any-name', array: [ { _id: 'any-id', a: 'any-a-data', b: 'any-b-data', c: 'any-c-data' }, ...more objects ] }

I want to call updateOne method and update the entire object in array with _id = 'any-id' with the folowing object

 { a: 'new-a-data', b: 'new-b-data', c: 'new-c-data' }

so the result will be:

{
  name: 'any-name',
  array: [
    { _id: 'any-id', a: 'new-a-data', b: 'new-b-data', c: 'new-c-data' },
    ...more objects
  ]
}

I trying something like:

 model.updateOne( { 'array._id': _id }, { $set: { 'array.$': data } } )

data = { a: 'new-a-data', b: 'new-b-data', c: 'new-c-data' }

can someone help me?

Answer 1

You need to parse the new data before updating the document:

var { newA, newB } = data;

Model.updateOne({ 'array._id': 'any-id' }, {
    '$set': {
        'array.$.a': newA,
        'array.$.b': newB
    }
})
.then((data) => { console.log(data); res.redirect('/') })
.catch((err) => res.status(500).send("Error: ", err));
