Validating With Failures

In cbValidation 1.5 we introduced the validateOrFail() function. This function works in similar manner to the validate() method, but instead of giving you the results object, it throws an exception of type ValidationException.

Incoming Target	Validation Fails	Result
Object	false	Returns the same object
Object	true	Throws ValidationException
Struct	false	Returns the structure with ONLY the fields that were validated from the constraints
Struct	true	Throws ValidationException

Exception Extended Info

So your validation fails, where are the results? In the exception structure under the extendedInfo key. We store the validation results as JSON in the extended info and then you can use them for display purposes:

try{
    validateOrFail( target );
    service.save( target );
} catch( ValidationException e  ){
    return {
        "error" : true,
        "validationErrors" : deserializeJSON( e.extendedInfo )
    };
}
