Re: how to adress specific data from related models?

Hi Paul, I heard your scream still here in Germany ;-)
Thanks so far .. it is hard to learn cake with only one book in my
native language and two other books written in english but nor realy
wrote to fit my needs (they are more done to show hot to do a specific
project with cake).

I think with your help and use of the debug() function I managed to
solve the problem so far. - this time ...
It looks as if I still have problems to use the multidimensional
arrays inside of cake in the right manner/way because indexing makes a
lot of trouble.

The code yiu posted here to me still did me some error messages till I
changed some parts and got this:

$Y1=$this->Lodging-
>find('first',array('conditions'=>array('Lodging.id'=>$this-
>data['BookingPosition']['lodging_id'])));
//debug($Y1);
echo $Y1['Lodging']['NumberOfBeds'];

as part of my own custom validation function inside the model.

It's the same rersult like my quick and dirty code I posted before
$A = $this->query("SELECT Bettenanzahl FROM Lodgings WHERE
id=" . $this->data['BookingPosition']['lodging_id'] );

So thanks a lot for showing me there is a better way than using a
query; I'll try to keep in mind the find () syntax
..... started to do me my own cake sheet/minibook to keep all the
hints I get here :)

Now I can proceed with my project and shure soon with new questions as
well.

Have a nice weekend.

Michael
