# Validation extension to Gisele model library

Adds validation capabilities to any Gisele.Model instances

## Usage

```js

var User = Gisele.Model.create({

    name: { type: String, required: true, minlength: 15 },

    age: { type: Number, min: 18 }

});

var bob = new User({

	name: 'Bob',

	age: 15

});

// runs the validation rules of each field

bob.$$.validate();

console.log(bob.$$invalid);

// true

console.log(bob.$$errors);

//  {

//     name: { minlength: true },

//     age: { min: true }

//  }

```

## Validation of custom fields

New field types must implement a `validate()` method that either returns `true` (is valid) or an object with the validation errors.

In the builtin fields they are key/value pairs with the key being an error and the value being true, as same as `bob.$$errors` above.

Example:

```js

class Foo() { }

class FooField extends Gisele.Field {

	parse(value) { return new Foo(value); }

	validate(value) {

		// any validation rule can be applied

		if (this.required && value instanceof Foo) {

			return { required: true };

		}

		return true;

	}

}

Gisele.Field.add(Foo, FooField);

```
