		}

		$validator = $this->validator->make($this->attributes, static::$rules, static::$messages);

		if ($validator->passes()) return true;

		$this->setErrors($validator->messages());

		return false;
	}

	/**

	protected function setErrors($errors)
	{
		$this->errors = $errors;
	}

	/**

	 */
	public function getErrors()
	{
		return $this->errors;
	}

	{

	}
}

This breaks on inserts for me because my rule is checked also on inserts and when the model is new and therefore has no id, it passes an empty string as the id to search for.

I've replaced $replace = ($this->getKey() > 0) ? $this->getKey() : ''; with $replace = ($this->getKey() > 0) ? $this->getKey() : 0;. Seems to fix the problem.
