I think you can use $ operator to do this.
The positional $ operator identifies an element in an array to update without explicitly specifying the position of the element in the array.
Now you have two options, to either update the individual fields (only the ones you want to) or update the whole object. For both of them you need $set :
Just pass the query as first argument of your update query and the second argument is your update clause.
Collection.update({'devices.device_name' : 'Test456356'}, {
{ '$set': { 'devices.$': {
"ime_number" : "888844442222",
"device_name" : "Remote Device",
"subscription_type" : "Monthly",
"validity" : 30,
} } }
});
Note: above updates all the elements found with the query. If you want to be specific you can use updateOne. Just replace update with updateOne and it will update the first matched document
