Hi guys,

I have a noob question regarding Orchard Localization:

I have a ViewModel inside my Orchard module that implements IValidatableObject interface. My problem is that I can't localize the validation messages:
public Localizer T { get; set; }

public LastMinuteVisitsModel()
      this.T = NullLocalizer.Instance;

if (this.RegionId <= 0)
    yield return new ValidationResult(T("Please select Region").Text);
Thanks in advance for your help!

The problem is that your view model is instantiated either manually or using the DefaultModelBinder.
Although I am not sure, I don't think the DefaultModelBinder will inject a Localizer when you expose a public Localizer T (although you could surely try).
If it doesn't then perhaps it would be interesting to think about implementing such a model binder.

Alternatively, move your validation logic out of the view model and into the controller.

I have the same issue, and I did not find the alternative where I do the validation in the controller nice, so I ended ut using this metod:

Did you by any chance find a better way? Perhaps you do it through the DefaultModelBinder. If you did please share :-)

Hi again,

sfmskywalker is right: DefaultModelBinder doesn't inject the Localzier. To avoid that, I instatiated manually my model inside my action from the controller and then pass the controller's localizer.
        public ActionResult SearchLastMinuteVisits()
            LastMinuteVisitsModel filters = new LastMinuteVisitsModel();
            filters.T = this.T;

Thanks again for your time!
