Configuration File

← Declaring Constraints

You can optionally register shared constraints in your configuration file. This means you register them with a name of your choice and its value is a collection of constraints for properties in your objects or form. Later on you will reference the key name in your handlers or wherever in order to validate the object or form. Here is an example:

validation = {
	sharedConstraints = {
		sharedUser = {
			fName = {required=true},
			lname = {required=true},
			age   = {required=true, max=18 }
			metadata = {required=false, type="json"}
		},
		loginForm = {
			username = {required=true}, password = {required=true}
		},
		changePasswordForm = {
			password = {required=true,min=6}, password2 = {required=true, sameAs="password", min=6}
		}
	}
}

As you can see, our constraints definition describes the set of rules for a property on ANY target object or form.
