Méthode non trouvée - findOrCreateWhere - Gorm

Question

J'ai créé une classe de rôle qui ne contient qu'une seule autorité variable:

class Role { 
    String authority 
} 

Maintenant, lorsque je tente d'enregistrer de nouvelles valeurs dans BootStrap.groovy (Grails app) Je fais cela :

def adminRole = Role.findOrCreateWhere(authority: "ROLE_ADMIN"); 

Quand je courais ce que je reçois l'exception suivante:

2012-01-29 23:35:03,067 [Thread-9] ERROR org.codehaus.groovy.grails.web.context.GrailsContextLoader - Error executing bootstraps: groovy.lang.MissingMethodException: No signature of method: org.rango.auth.Role.findOrCreateWhere() is applicable for argument types:() values: []

Quel est le problème avec mon code?

Merci!

essayez ceci: def adminRole = Role.findOrCreateWhere ([autorité: "ROLE_ADMIN"]);
