Hi to all

I would like to know how to perform a partial update / new insert on a collection?

I have a update end point in patch that contains only some property of a collection with different kind of properties.

Example i have a collection like this

https://jsoneditoronline.org/?id=5d1cb75ba2de4626ab2a4628e29b955e

Update end-point request body

Update query in go:

 var docs models.Events var docs models.Events if err = json.Unmarshal(bodyBytes, &docs); err != nil { return nil, err }
 
newObj := bson.M{"$set": docs} newObj := bson.M{"$set": docs}
 result, err := collection.UpdateOne(context.Background(), bson.M{"_id": _id}, newObj) if err != nil { return nil, err } fmt.Print(result.ModifiedCount)

In this case all old content of assets are deleted.

Is there a way to perform a partial update / insert without deleting old records?
