Re: BelongsToMany model

You also have control over what is the foreignKey to use when creating the association. Refer the the ORM docs to customize what the query builder is doing.

There is no "public $primaryKey" in CakePHP 3.0

You may use $this->primaryKey($myKey) inside the initialize() method

I have made two tables leerlingen and verzorgers. Because these have a many to many relation i added a table leerlingen_verzorgers.
I have added 3 model tables:

class VerzorgersTable extends Table {
    public $primaryKey = 'verzorger_id';
   
    public function initialize(array $config) {
        $this->belongsToMany('Leerlingen',
            ['through' => 'LeerlingenVerzorgers',]);
        $this->addBehavior('Timestamp');
    }
}

class LeerlingenTable extends Table {
    public $primaryKey = 'leerling_id';
   
    public function initialize(array $config) {
        $this->belongsToMany('Verzorgers',
            ['through' => 'LeerlingenVerzorgers',]);
        $this->addBehavior('Timestamp');
    }
}

class LeerlingenVerzorgersTable extends Table {
    public function initialize(array $config) {
        $this->belongsTo('Leerlingen');
        $this->belongsTo('Verzorgers');
    }
}

Now when i want to retrieve a verzorger with all the leerlingen i get an error that he doesn't know the leerlingen_id this is right because it is leerling_id. But with the verzorgers table he does use the right id and asks for the verzorger_id.

My relation table looks like this:
leerlingen_verzorgers
--------------------------
id
leerling_id
verzorgers_id
jaar

The generated query looks like this:

'SELECT Leerlingen.leerling_id AS `Leerlingen__leerling_id`, Leerlingen.voornaam AS `Leerlingen__voornaam`, Leerlingen.achternaam AS `Leerlingen__achternaam`, Leerlingen.geboortedatum AS `Leerlingen__geboortedatum`, Leerlingen.geslacht AS `Leerlingen__geslacht`, Leerlingen.email AS `Leerlingen__email`, Leerlingen.opmerking AS `Leerlingen__opmerking`, LeerlingenVerzorgers.id AS `LeerlingenVerzorgers__id`, LeerlingenVerzorgers.leerling_id AS `LeerlingenVerzorgers__leerling_id`, LeerlingenVerzorgers.verzorger_id AS `LeerlingenVerzorgers__verzorger_id`, LeerlingenVerzorgers.jaar AS `LeerlingenVerzorgers__jaar` FROM leerlingen AS Leerlingen INNER JOIN leerlingen_verzorgers LeerlingenVerzorgers ON (LeerlingenVerzorgers.verzorger_id IN (:c0) AND Leerlingen.leerling_id = (LeerlingenVerzorgers.leerlingen_id))

so first he uses the right leerling_id but at the end he uses leerlingen_id. Anyone knows what i did wrong?
