Re: how to adress specific data from related models?

If you are doing this from within the BookingPosition model, '$this' points to the BookingPosition model. So by trying to access $this->BookingPosition you are in fact trying to access $this->BookingPosition->BookingPosition, if that makes sense! Instead, try $this->Lodging->field...etc. This should work, so long as you have a relationship set up between BookingPosition and Lodging in the models. If you are accessing this from a controller, then you need to use $this->BookingPosition->Lodging...etc
