Grails i18n From Database but Default Back To File

Question

Following this blog article I enabled my application to load i18n messages from the database. It works great. However, I don\'t want to manage all messages in the database

Answer 1

You may extend ReloadableResourceBundleMessageSource (the original grails message bundle, which does not seem to be final) instead and then apply this code:

class DatabaseMessageSource extends ReloadableResourceBundleMessageSource {
  protected MessageFormat resolveCode(String code, Locale locale) {
    Message msg = Message.findByCodeAndLocale(code, locale)
    def format = null
    if (msg) {
      format = new MessageFormat(msg.text, msg.locale)
    }else{
      format = super.resolveCode(code,locale)
    }
    return format;
  }
}

You may also reconfigure your message resources in Resources.groovy:

 beans = {
    messageSource(com.mycompany.DatabaseMessageSource) {
        basename = "WEB-INF/grails-app/i18n/messages"
    }
 }
