On prepare validator and error with saving model.


I want to use on prepare validator to save changes to the model in "audit object" and I have one question. On prepare validator is called before saving the model it is possible that I save old/new values to "audit object" but in reality the model wouldn't be saved to the DB (for instance there will be problems with validation or there will be problem with connections to DB). Is there any solution to this problem ? How to save date to "audit object" using interceptor "before saving" but be sure that date was really saved ? I cannot use Hybris auditing mechanism because changes are not made by hmc but by custom cockpit.

Thanks in advance.

    here you can read about transactions and how to deal with them in hybris. You may also use code like in the sample to extract data about model changes:

     final ItemModelContext itemModelContext = ModelContextUtils.getItemModelContext(itemModel);
       if (itemModelContext != null)
         ModelValueHistory mvh = ((ItemModelContextImpl) itemModelContext).getValueHistory();
         //Some logic here to aggregate the history
         //Probably for storin it 
      modelService.saveAll(/*model & hisroty data*/)

    Cheers, Wojtek
