The +validates_with+ helper takes a class, or a list of classes to use for validation. There is no default error message for +validates_with+. You must manually add errors to the record's errors collection in the validator class.
The validator class has two attributes by default:
* +record+ - the record to be validated
* +options+ - the extra options that were passed to +validates_with+
To implement the validate method, you must have an +record+ parameter defined, which is the record to be validated.
Like all other validations, +validates_with+ takes the +:if+, +:unless+ and +:on+ options. If you pass any other options, it will send those options to the validator class as +options+:
