Idea: Next level Model Properties

[JasonTheAdams]

class Model {
	protected static function properties() {
		return [
			(new ModelProperty('firstName')) // default type is 'string'
				->type('string'),
				->requiredOnSave() // can be made without, but cannot be saved without (as opposed to required())
				->validationRule(), // use the Validation library???
				
			(new ModelProperty('lastName'))
				->type('string')
				->default('Jones'),

			(new ModelProperty('weight'))
				->type('int', 'float') // variadic, assumes union type
				->default('Jones')
				->cast(function($value, $property) { return (float) $value }),

			(new UpdatedAtProperty()), // Supports ModelProperty subclasses 🤯

			'email' => ['string', 'foo@example.com']
		];
	}
}

Notes:

• This is merged with $properties parsed into the $propertiesCollection static property once
• The final shape is the key is the property name and the value is a ModelProperty
• For explicit ModelProperty instances the key is taken from the instance
• For short-hand properties they're parsed into a ModelProperty
• Also introduce a ModelPropertiesCollection class to get things such as "required properties"
