You can do something like this

const Validations = buildValidations({
  foo: validator(function(value, options, model, attribute) {
    if (model.get('errors').has(attribute)) {
      return model.get(`errors.${attribute}.messages.firstObject`);
    }
    return true;
  }, { dependentKeys: ['errors.foo.messages.[]']})
});

it is not working for embedded belongs to and has many relationships..

You have to put your validations on the model that has the errors. You cant validate child on model.child if that makes sense...

On a side note: @blimmer is this the sort of issue you have been facing as well? Would it help to have a validator('ds-error') that handles the dependentKeys and spits out the last error for the given attribute?

@offirgolan that would be helpful - it would be especially helpful if it could identify the model property and mark that invalid (e.g. on a user form, highlight what is invalid like birthdate).
