Validation

Validation rules are stored in the model in the static $rules property. The syntax is just normal Laravel validation, keyed to your column name.

Validating images

To support validating images (which are stored in another table), Decoy adds support for “dot” notation in the rules array for specifying the image to be validated.

Custom validation

An easy way to add custom validation to models is by specifying an onValidating method, taking the $validation object, adding errors to it, and returning it. Special logic in the Base Controller’s validate method will see the returned Validator and its errors and respond appropriately.

public function onValidating($validation) {
	$validation->errors()->add('last_name', 'This last name sucks');
	throw new \Bkwld\Decoy\Exceptions\ValidationFail($validation);
}

Here’s an example of how to set unique exceptions for the current model instance when updating. This example assumes that the unique rule is the 3rd (the 2nd offset) rule defined for the name field. This allows us to just append the id onto it.

public function onValidating($validation) {
	if ($this->exists) {
		$rules = $validation->getRules();
		$rules['name'][2] .= ','.$this->getKey();
		$validation->setRules($rules);
	}
}
