Custom Validators

You can build also your own validators by implementing our interface cbvalidaton.models.validators.IValidator :

The arguments received are:

validationResults : The validation result object
field : The field or property in the object that is in validation
targetValue : The value to test

Here is a sample validator:

WARNING: You can't do a normal wirebox mapping for YourOwnValidator in your main application. A validator needs an IValidator interface from the cbvalidation module. When wirebox inspects the binder, the cbvalidation module is not loaded yet, so it will error. This can be solved by defining your custom validators in an own module (depending on cbvalidation) or by mapping your validator in the afterConfigurationLoad() method of your binder, e.g in config/wirebox.cfc
