@NullVoxPopuli https://github.com/NullVoxPopuli Looking at your code.
Seems like the attendance model doesn't have the level relation, are you
using there an attendance or an event-attendance (which is the one with
the realtion) ?
The validation looks good and should be working as you have it there.

I have this currently:

        custom: {
          message: 'Level is required for the selected ticket.',
          // value may be a promise here
          // so we need to see if we can access the
          // id property on it
          validation(key, value, model){
            let requiresLevel = model.get('package.requiresTrack');
            debugger;
            if (requiresLevel){
              // value is undefined, and level is a promise
              return Ember.isPresent(model.get('level'));
            }

            return true;
          }
        }

@NullVoxPopuli You need to add that validation directly on the relation. Could you show me your entire model.

from ember-model-validator.

here is the model: https://github.com/NullVoxPopuli/aeonvera-ui/blob/master/app/models/attendance.js#L66

here is how I'm validating it: https://github.com/NullVoxPopuli/aeonvera-ui/blob/master/app/services/order-cart.js#L153

(I'm just calling validate() on the attendance)

@NullVoxPopuli Let me know if that works so I can close this issue. Thank you.

Ok, so I finally move the level validation to the event-attendance:

So maybe it's just a logic thing. Cause if I change my isPresent check to be on model.get('level.id'), it works just fine ('throws' a validation error via validate())

from ember-model-validator.

Though, I think it would be great to have bulit in if: keys on the relationship validators, like, I would like to do:

validations: {
  level: { 
    presence: true,
    if: 'model.package.requiresTrack'
  }
}

also, it appears validations get extended from superclass to subclass :-\ I'll open that as a seperate issue
