Take a look at the project validator files. They have a structure whereby there's a set of validation methods. In general they have this structure:
There is a validate() method validates the entire object by calling methods to validate each of the fields in the object (for example, validateFirstName()). This field-specific validation method validates the field by calling methods to validate specific details about the field (for example, that it's too long, that it's provided, that it's the correct data type). Any one of these methods can be overridden. This means that if you wanted to validate some specific details about a field that you could override the field validator method to call the super object's field validator method and then your own method to validate a specific detail of an object. For example, in the ReactorBlog sample app the UserValidator has been customized. See /blog/data/Validator/UserValidator.cfc. This customization makes sure that the username is unique. You'll note that I override the validateUsername method (which is in the project UserValidator). It calls user.validateUserName() and then calls validateUsernameIsUnique. This method uses a gateway to make sure that the provided username hasn't been used before. If I wanted I could also validate any other information I want following this same pattern.

Makes sense. What would I do if I wanted to add additional validation? Before, I would just continue adding errors to the ValidationErrorCollection object. What would I do now? Is it as easy as overriding the validate() method (making sure to call before/afterValidate()), and add my own checks?

Does validate() throw an error when validate fails, or something?

I would guess you create a method called 'validate', have it call super.validate() and then do your additional checks. -- Tom Chiverton -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Reactor for ColdFusion Mailing List [email protected] Archives at: http://www.mail-archive.com/reactor%40doughughes.net/ -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Reactor for ColdFusion Mailing List [email protected] Archives at: http://www.mail-archive.com/reactor%40doughughes.net/ -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
