## Ajouter des validations par expressions régulières

On peut définir une <abbr title="Une expression régulière, regex ou regexp est une suite de caractères qui définit un pattern de correspondance pour les chaînes de caractères.">expression régulière</abbr> à laquelle le paramètre doit correspondre :

constraints.NotNull.message = {item} is niet ingevuld.
constraints.Null.message = {item} moet null zijn.
constraints.Past.message = {item} moet een waarde uit het verleden zijn.
constraints.Pattern.message = {item} komt niet overeen met "{regexp}".
constraints.Size.message = De grootte van {item} moet tussen {min} en {max} tekens liggen.
# ----------------------------------------------------------
# Hibernate Validator
# -------------------

constraints.NotNull.message = {item} обязательно.
constraints.Null.message = {item} должно быть null.
constraints.Past.message = {item} должно быть прошлым значением.
constraints.Pattern.message = {item} не соответствует "{regexp}".
constraints.Size.message = Размер {item} должен быть от {min} до {max}.

var validRegionRegex = regexp.MustCompile("^[a-zA-Z][a-zA-Z0-9-_-]+$")

// validSiteNameRegex - allows lowercase letters, digits and '-', starts with
// letter. At least 2 characters long.
var validSiteNameRegex = regexp.MustCompile("^[a-z][a-z0-9-]+$")

// LookupSite - get site related configuration. Loads configuration from legacy

constraints.NotNull.message = {item} ist erforderlich.
constraints.Null.message = {item} muss null sein.
constraints.Past.message = {item} muss ein vergangener Wert sein.
constraints.Pattern.message = {item} stimmt nicht mit "{regexp}" überein.
constraints.Size.message = Die Größe von {item} muss zwischen {min} und {max} liegen.
