-Rails can also be specify strict validations. You can use the +:strict+ option to set that validation as strict. If an object fails a strict validation then an +ActiveModel::StrictValidationFailed+ error message is raised.

 h3. Conditional Validation
 
 Sometimes it will make sense to validate an object just when a given predicate is satisfied. You can do that by using the +:if+ and +:unless+ options, which can take a symbol, a string or a +Proc+. You may use the +:if+ option when you want to specify when the validation *should* happen. If you want to specify when the validation *should not* happen, then you may use the +:unless+ option.
