CakePHP Simple table association assistance - cakephp

Question

I'm really struggling with a table association in cakephp, all I'm trying to do is associate two tables together, however one table has two two foreign keys to the other table.
For some reason, I cannot get any information to be displayed in the field select form for home_id ....
Please see the database picture below and the associated code.
I'm really new to cakephp but feel if I can nail this it will be really useful - any help is greatly appreciated.
Database Schema
class SafcTeam extends AppModel {
var $name = 'SafcTeam';
var $displayField = 'name';
var $validate = array(
'name' => array(
'notempty' => array(
'rule' => array('notempty'),
),
),
'badge' => array(
'notempty' => array(
'rule' => array('notempty'),
),
),
);
var $hasMany = array(
'SafcTeam' => array(
'className' => 'SafcEvent',
'foreignKey' => 'home_id',
)
);
}
class SafcEvent extends AppModel {
var $name = 'SafcEvent';
var $displayField = 'id';
var $validate = array(
'safc_matchtype_id' => array(
'numeric' => array(
'rule' => array('numeric'),
),
),
'safc_league_id' => array(
'numeric' => array(
'rule' => array('numeric'),

Answer 1

you have to use an alias for each of this relation of your SafcTeam Model:
var $belongsTo = array(
//relationship for your home_id fk
'SafcHomeTeam' => array(
'className' => 'SafcTeam',
'foreignKey' => 'home_id'
),
//relationship for your away_id key
'SafcAwayTeam' => array(
'className' => 'SafcTeam',
'foreignKey' => 'away_id'
)
);
and also in the related safc team model :
var $hasMany = array(
'SafcHomeTeam' => array(
'className' => 'SafcEvent',
'foreignKey' => 'home_id',
),
'SafcAwayTeam' => array(
'className' => 'SafcEvent',
'foreignKey' => 'away_id',
)
);
In your SafcEvents controller in the action add and edit add this:
//to respect cake conventions need the select list to be plural (Teams <--- with a s at the end)
$safcHomeTeams = $this->SafcEvent->SafcHomeTeam->find('list');
$safcAwayTeams = $this->SafcEvent->SafcAwayTeam->find('list');
//also pass those list to the view
$this->set(compact('SafcAwayTeams', 'SafcHomeTeams));
In the safcevent view Add and Edit
in the form section :
//to respect cake convention to construct your select input properly
//you need to refere to the list established in the controller ($SafcHomeTeams by using $SafcHomeTeam_id <--singular + "_" + "id")
echo $this->Form->input('SafcAwayTeam_id');
echo $this->Form->input('SafcHomeTeam_id');

Answer 2

Cake does not support complex FK out the box, you can define a relation with conditions like so
public $hasMany = array(
'TheRelation' => array(
'foreignKey' => false,
'conditions' => array(
... conditions ...
)
)
)
