You can optionally register constraints in your ColdBox configuration file under the validation
directive. This means you register them with a unique name of your choice and its value is a collection of constraints for fields in your objects or forms. These will be called lovingly Shared Constraints.
Here is an example:
config/ColdBox.cfcvalidation = {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 by unique key name.
You can then use the keys for those constraints in the validation calls:
validate( target, "sharedUser" );​validate( rc, "loginForm" );​validate( rc, "changePasswordForm" );
