Mongoose virtual fields included in toJSON by defa

Question

I saw in another answer that in order to include the virtual fields you must do like https://groups.google.com/forum/?fromgroups#!topic/mongoose-orm/HjrPAP_WXYs

var schemaOptions = {
  toJSON: {
    virtuals: true
  }
};

which I've done;

Now in the Schema:

 new Schema({...}, schemaOptions);

But still so, the data doesn't include the virtual.. :s

But like this works:

var docsCallback = function(err, docs){
    var i = docs.length;
    var nDocs = [];
    while(i--){
        nDocs[i] = docs[i].toObject({virtuals: true});
    }
    done(nDocs);
}

Answer 1

You can do this way as well:

docs.set('toJSON', { virtuals: true });

Answer 2

Just tried:

  var schemaOptions = {
    toObject: {
      virtuals: true
    }
  };

and worked! ;)

Now by default I use:

  var schemaOptions = {
    toObject: {
      virtuals: true
    }
    ,toJSON: {
      virtuals: true
    }
  };

Answer 3

For me it worked only after adding getters: true to schema options, as mentioned in mongoose docs, i.e.

var schemaOptions = { toObject: { getters: true }, toJSON: { getters: true } };
