Hi,
I have a model set up like this:
class Question extends AppModel {
var $name = 'Question';
var $hasAndBelongsToMany = array(
'FunctionalArea' => array('joinTable' => 'question_functions')
);
var $validate = array(
'title' => 'notEmpty',
'content' => 'notEmpty',
'FunctionalArea' => array(
'rule' => array('multiple', array('min'=>1)),
'required' => true
)
);
}
Then in my form I set up an input with FunctionalArea as the field
name, using Cake's form helper. This produces an input with name="data
[FunctionalArea][FunctionalArea][]". Now if I save the form with NO
validation, the vanilla $this->Question->save($this->data); works just
fine. The join table is all correct after saving.
But when I put in that validation for FunctionalArea that I have in
the above code, the validation doesn't work correctly. The model's
invalidFields method does this:
if (isset($data[$this->alias])) {
$data = $data[$this->alias];
}
So that the data in data[FunctionalArea][FunctionalArea] never gets to
the validate method. So the validation always fails (because
FunctionalArea is required).
My question is: what is the correct Cake way to do this? I'm trying to
use the automatic save feature, form fields, and the validation, but I
don't see how I can use them together, because the validation seems to
be ignoring the very place where the save needs the data.
