I am trying to update nested object using mongoose. I am trying to update the "remindTime date" only and keep the "time" I can update the "remindTime date" however it erases my "remindTime time" property.
I have try the following and none of them work
Model.updateMany(req.query, { remindTime: { date: "2021-09-28" } })
Model.updateMany(req.query, { remindTime: $set:{ { date: "2021-09-28" } } } )
Database data that I am updating
{
"_id": {
"$oid": "614d3cedfb2600340fdb28f9"
},
"date": "2021-09-23",
"title": "First test",
"description": "not working yet",
"remindTime": {
"date": "2021-09-28",
"time": "01:20 am"
},
"isComplete": false,
}

Please try this:
Model.updateMany(req.query, { "remindTime.date": "2021-09-28"})
You can use dot notation:
According to docs:
MongoDB uses the dot notation to access the elements of an array and to access the fields of an embedded document.
To specify or access a field of an embedded document with dot notation, concatenate the embedded document name with the dot (.) and the field name, and enclose in quotes:
"<embedded document>.<field>"
So the query:
Model.updateMany(req.query,
{
"$set": {
"remindTime.date": "new date"
}
})
