<h1>Error handling</h1>
<p>Errors returned after failed validation contain an <code>errors</code> object holding the actual ValidatorErrors. Each ValidatorError has a <code>type</code> and <code>path</code> property providing us with a little more error handling flexibility.</p>
<pre><code>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"
});
</code></pre>
<p>BTW, the <code>err.errors</code> object is also available on the model instance.</p>
<pre><code>toy.errors.color.message === err.errors.color.message
