Mongoose save() not updating value in an array in database document

arrays node.js mongodb for-loop mongoose

Maybe notify mongooose the dataset has changed like this :

doc.markModified('pathToYourAttribute')

person.anything = { x: [3, 4, { y: "changed" }] }; person.markModified('anything');

Hope it helps!

Refer to this issue. One way to solve this would be not to update your array via the classic array Index method. So do this

doc.array.set(index, value);

Instead of

doc.array[index] = value;

also view the FAQ and doc for more details.

I replaced the save method with this statement:

Client_data.Unit.updateOne({_id: unit._id},unit);
