Using mongoose to add new field to existing document in mongodb through update method

Question

I\'m trying to update a mongodb document with mongoose in node.js

When the field exists, the update works, but if the field does not exist, the update will not work.

Answer 1

Try the following code:

User.update(
     {uid: 'uid'}, 
     {vehicle_status : 'vehicleSatus' },
     {multi:true}, 
       function(err, numberAffected){  
       });

Also, make sure that you add vehicle_status to the schema.
