DigiComp.SettingValidator ------------------------- This Package allows configuring Validators for your Action-Arguments or domain model properties to be set by a new Yaml-File in your Configuration directory. Let's imagine you had this action-method: /** * @Flow\Validate(argumentName="order", type="DigiComp.SettingValidator:Settings") * @param Order $order */ public function createOrder($order) {...} Then your Validation.yaml could look like this: Vendor\Package\Domain\Model\Order: # validates the complete object self: 'Vendor.Package:SomeOtherValidator': [] # validates properties of the object properties: price: NumberRange: maximum: 20 minimum: 10 customer: 'DigiComp.SettingValidator:Settings': name: 'OrderCustomer' OrderCustomer: properties: firstName: StringLength: minimum: 3 maximum: 20 As you see: Nesting is possible ;) That way you can easily construct flexible structures. The SettingsValidator has an optional option: "name" - If you don't give one, it assumes your validation value is an object and searches in Validation.yaml for the FQCN.
