Is it possible to inherit virtuals as well?

[miliu99]

I have some virtuals for populating data. It would be nice if those virtuals would be inherited too.

You can use the third argument. Here is the signature of the function: extendSchema(Schema, definition, options). But I can't check now if it possible to get instance options (virtuals) to inherit them.

I have a sample that may help. It leverages the transpiled version of extends from ES6

const mongoose = require("mongoose");

function extendSchema(parent, child, options) {
  let updated_schema = Object.assign({}, parent.obj, child);
  let updated_child_object = new mongoose.Schema(updated_schema, options);
  __extends(updated_child_object, parent);
  return updated_child_object;
}

var __extends =
  (this && this.__extends) ||
  function(d, b) {
    for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
    function __() {
      this.constructor = d;
    }
    d.prototype =
      b === null ? Object.create(b) : ((__.prototype = b.prototype), new __());
  };

module.exports = extendSchema;

Let me know if you want me to put a pull request in for this.
