Multiple hasMany associations with CakePHP model via column aliases - mysql

Question

I'm making a little app for my softball team. I want to set up the following associations:
Model Game has two columns, away_id, home_id, both of which are aliases to Team.id.
In Game model I have:
/**
* belongsTo associations
*
* #var array
*/
public $belongsTo = array(
'Home' => array(
'className' => 'Team',
'foreignKey' => 'home_id', // also tried simply 'id'
'conditions' => '',
'fields' => '',
'order' => ''
),
'Away' => array(
'className' => 'Team',
'foreignKey' => 'away_id', // also tried simply 'id'
'conditions' => '',
'fields' => '',
'order' => ''
)
);
In Team model I have:
public $virtualFields = ['home_id' => 'Team.id', 'away_id' => 'Team.id'];
And:
/**
* hasMany associations
*
* #var array
*/
public $hasMany = array(
'Game' => array(
'className' => 'Game',
'foreignKey' => 'home_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
),
// also tried only one 'Game' association with foreignKey => [home_id, away_id]
'Game' => array(
'className' => 'Game',
'foreignKey' => 'away_id',
'dependent' => false,
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'exclusive' => '',
'finderQuery' => '',
'counterQuery' => ''
)
);
Getting the following error:
Note: "Psychouts" is the only non-self-explanatory appearance in the SQL below; it's the database name (and also my team name, henh).
Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Team.id' in 'field list'
SQL Query: SELECT Game.id, Game.when, Game.cancelled, Game.field, Game.home_id, Game.away_id, Game.score_us, Game.score_them, Home.id, Home.captain_id, Home.name, Home.wins, Home.losses, Home.ties, Home.scored, Home.allowed, (Team.id) AS Home__home_id, (Team.id) AS Home__away_id, Away.id, Away.captain_id, Away.name, Away.wins, Away.losses, Away.ties, Away.scored, Away.allowed, (Team.id) AS Away__home_id, (Team.id) AS Away__away_id FROM psychouts.games AS Game LEFT JOIN psychouts.teams AS Home ON (Game.home_id = Home.id) LEFT JOIN psychouts.teams AS Away ON (Game.away_id = Away.id) WHERE 1 = 1 LIMIT 20

Answer 1

Following AD7six's comments, the solution which, after testing, seems correct is:
In Team model, erase the virtual fields I'd proposed and then define Game association as follows:
/**
* belongsTo associations
*
* #var array
*/
public $belongsTo = array(
'Game' => array(
'className' => 'Game',
'foreignKey' => ['OR' => ['Game.home_id = Team.id', 'Game.away_id = Team.id']]
'conditions' => '',
'fields' => '',
'order' => ''
),
);
And in Game model, define Team association as usual:
/**
* belongsTo associations
*
* #var array
*/
public $belongsTo = array(
'Team' => array(
'className' => 'Team',
'foreignKey' => 'id',
'conditions' => '',
'fields' => '',
'order' => ''
),
);
