var ToySchema = new Schema({
    color: String
  , name: String
});

var Toy = db.model('Toy', ToySchema);

Toy.schema.path('color').validate(function (value) {
  return /blue|green|white|red|orange|periwinkel/i.test(value);
}, 'Invalid color');

var toy = new Toy({ color: 'grease'});

toy.save(function (err) {
  // previous behavior (v1x):

  console.log(err.errors.color)
  // prints 'Validator "Invalid color" failed for path color'

  // new v2x behavior - err.errors.color is a ValidatorError object

  console.log(err.errors.color.message)
  // prints 'Validator "Invalid color" failed for path color'

  // you can get v1 behavior back by casting error.color toString

  console.log(String(err.errors.color))
  // prints 'Validator "Invalid color" failed for path color'

  console.log(err.errors.color.type);
  // prints "Invalid color"

  console.log(err.errors.color.path)
  // prints "color"

  console.log(err.name)
  // prints "ValidationError"

  console.log(err.message)
  // prints "Validation failed"
});
