3 Utility Clases

3.1 CountrySelectorService

Example domain class Address.groovy

class Address {
   def countrySelectorService
   String country
   static constraints = {
      country(nullable: false, blank: false, validator: {val, obj ->
               def allowedCountryCodes = obj.countrySelectorService.allowedCountryCodes()
               if(!allowedCountryCodes.contains(val))
                  return "org.grails.plugins.countrySelector.country.notAllowed"
            })
   }
}

The Address class is usually an embedded class placed in groovy/src for a certain domain class. To use the countrySelectorService, you need to inject the service differently:

import grails.util.Holders
class Address {
   String country
   static constraints = {
      country(nullable: false, blank: false, validator: {val, obj ->
               def allowedCountryCodes = obj.countrySelectorService.allowedCountryCodes()
               if(!allowedCountryCodes.contains(val))
                  return "org.grails.plugins.countrySelector.country.notAllowed"
            })
   }
   private static getCountrySelectorService() {
      def grailsApplication = Holders.getGrailsApplication()
      grailsApplication.mainContext.countrySelectorService
   }
}
