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

Question

I am trying to update a document in a collection (units) using GUI and after it gets updated I want to update the value (user.Units which is an array of Unit names) in collecti

Answer 1

Maybe notify mongooose the dataset has changed like this :

doc.markModified('pathToYourAttribute') 

From the docs http://mongoosejs.com/docs/schematypes.html

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

Hope it helps!

Answer 2

i replaced the save methud with this statment: Client_data.Unit.updateOne({_id: unit._id},unit);

Answer 3

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;
