Cake PHP automagic forms and multiple tables - validation

Question

I have a form with the following fields:
firstName
lastName
emailAddress
followed by (up to) ten name/email fields, like so
friendName-1
friendEmail-1
friendName-2
friendEmail-2
...
etc.
The firstName, lastName & emailAddress fields will be saved into a 'referrals' table, but 10 name/email pairs will go into a 'friends' table, containing a foreign key refferal_id.
Normally I use the cakephp 'automagic' forms, and set up my validation in the model, and do a $this->model->save(); If it fails I fall back on my model validation rules and the error messages get spat back into my form html. No problems.
How would I do this for TWO tables though? I'm thinking that the automagic stuff is not the way to go, but I feel I will lose a lot without it, such as validation in my models and custom error messages.
Is there a happy medium? I'm fairly new to cake so I'm wondering if theres a way to use automagic with multiple tables.

Answer 1

See http://book.cakephp.org/view/84/Saving-Related-Model-Data-hasOne-hasMany-belongsTo
Create the relationship in your Referral model:
var $hasMany = array('Friend');
Essentially, make sure you name your fields correctly, e.g.
echo $form->create('Referral');
echo $form->input('first_name');
echo $form->input('last_name');
echo $form->input('email');
foreach (range(0,9) as $index) {
echo $form->input('Friend.'.$index.'.name');
echo $form->input('Friend.'.$index.'.email');
}
echo $form->end();
And in your referrals controller:
function add() {
if(!empty($this->data)) {
$this->Referral->saveAll($this->data, array('validate'=>'first'));
}
}

First, I really hope that you don't have 20 fields in table called 'friendName-1', 'friendEmail-1', etc. Your second table should have 3 fields--your referral_id, friendname, and friendemail. If you don't want to normalize, then you don't need the second table.
But I digress, the way to keep your automagic forms is to put a "hasMany" in your referrals model and/or a "belongsTo" in your "friends" model. Then you can still use the FormHelper and Model->Save().
