node.js - Mongoose return data inside _doc object

Question

On mongoose find query execution, response data as multiple objects, the real data is in _doc property or field, its only occurs in some scenario. I can handle the data by getting Obj._doc.something, but i cant edit the data and save(mongoose model function). please help me to resolve this problem.

Note: Fields for schema has added dynamically.

PatientOrderMigration.find({ mrn: orderitem.mrn, visituid: orderitem.visituid },
function (err, orderDoc) 
{ 
//log data correctly.
console.log(orderDoc);
// undefined
console.log(orderDoc._id);
// correct data
console.log(orderDoc._doc._id);
}

Answer 1

I know this is old but I had similar issue. To fix this problem use .lean().

The lean option tells Mongoose to skip hydrating the result documents. This makes queries faster and less memory intensive, but the result documents are plain old JavaScript objects (POJOs), not Mongoose documents.

so your query would be:

PatientOrderMigration.find({ mrn: orderitem.mrn, visituid: orderitem.visituid }).lean()
