Advanced Custom Validators

You can use multiple custom validators or pass in arbitrary data to custom validators by specifying the validator name as the key in the rules struct.

this.constraints = {
    existsInDBValidator = {
        table = "table_name",
        column = "column_name"
    }
};

This example will look for an existsInDBValidator in WireBox and pass in { table = "table_name", column = "column_name" } to the validate method.

Using these advanced techniques you can build reusable validators that accept the data they need in the validationData struct. You can also include multiple custom validators just by specifying each of them as a key.

If you don't have any custom data to pass to a validator, just pass an empty struct ({})
