get _id with mongoose

I was trying to console.log(record._id) all of records on my mongodb collection using Mongoose. I kept getting undefined for each of the _id values.

I struggled until I bumped into this post. Then I used console.dir to find the location of the _id and used that in my console.log:

MySchemaModel.find({}).then(function(records) {



  records.forEach(function(record) {



    console.log(record._doc._id); // <-- I added ._doc

  });



});

But, this looks down-right hacky. Is there a better way to do this?

NOTE: This isn't just something that affects console.log. I'm just keeping the question narrow.

If you want to customize/edit record then you should use .lean() function.The .lean() function will turn it into a normal JavaScript object. If you don't use .lean() function then each record is still a mongoose document and _id behaves differently in that context. So can use like

MySchemaModel.find({}).lean().exec(function(error, records) {

  records.forEach(function(record) {

    console.log(record._id);

  });

});

N.B: when use .exec() then first parameter used for error and second one for success data.
