You could also add a model and id field, and set the belongsTo conditions in
Photo specifying foreignKey and conditions.
So you add two fields to table photos:
model
record_id
And then on Photo model:
<?php
class Photo extends AppModel
{
var $name = 'Photo';
var $belongsTo = array(
'Person' => array(
'foreignKey' => 'record_id',
'conditions' => 'Photo.model = \'Person\''
),
'Group' => array(
'foreignKey' => 'record_id',
'conditions' => 'Photo.model = \'Group\''
)
);
}
?>

Imagine a social networking site with people, groups, & photos:
- Person hasMany Photo
- Group hasMany Photo
- Photo belongsTo Person, Group
Then you'd need to do:
photos
- id
- person_id
- group_id
