Question

greatings!
my models are not being configured as containable. this following query dont display the correct result (i want to retrieve all the available cars between two dates in all category)

$car=$this->Genre->find('all', array(
                            'contain' => array(
                                'cars'=>array(
                                    'conditions'=>array(
                                        'cars.startdate <=' => $qdu ,
                                        'cars.enddate >=' => $qau
                                    )
                                )
                            )
                        )
                    );

this is my Genre model:

class Genre extends AppModel {
       public $actsAs = array('Containable');

    public $belongsTo = array(
    'houses' => array(
        'className' => 'houses',
        'foreignKey' => 'houses_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )
);

public $hasMany = array(
    'cars' => array(
        'className' => 'cars',
        'foreignKey' => 'genres_id',
        'dependent' => false,
        'conditions' => '',
        'fields' => '',
        'order' => '',
        'limit' => '',
        'offset' => '',
        'exclusive' => '',
        'finderQuery' => '',
        'counterQuery' => ''
    )
);

}

and this is car model:

class Car extends AppModel {

    public $belongsTo = array(
    'Genres' => array(
        'className' => 'Genres',
        'foreignKey' => 'genres_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )
);

public $hasMany = array(
    'ways' => array(
        'className' => 'ways',
        'foreignKey' => 'cars_id',
        'dependent' => false,
        'conditions' => '',
        'fields' => '',
        'order' => '',
        'limit' => '',
        'offset' => '',
        'exclusive' => '',
        'finderQuery' => '',
        'counterQuery' => ''
    )
);

}

Answer 1

Model names should normally be singular, so “Car” instead of “cars”.

$car=$this->Genre->find('all', array(
                            'contain' => array(
                                'Car'=>array(
                                    'conditions'=>array(
                                        'Car.startdate <=' => $qdu ,
                                        'Car.enddate >=' => $qau
                                    )
                                )
                            )
                        )
                    );

Also, make sure the Genre model loads the Containable behaviour.

class Genre extends AppModel {
   $actsAs = array('Containable');
}

Associations should also use singular, capitalised model names:

class Genre extends AppModel {
  public $actsAs = array('Containable');

  public $belongsTo = array(
    'House' => array(
        'className' => 'House',
        'foreignKey' => 'houses_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )
  );

  public $hasMany = array(
    'Car' => array(
        'className' => 'Car',
        'foreignKey' => 'genres_id',
        'dependent' => false,
        'conditions' => '',
        'fields' => '',
        'order' => '',
        'limit' => '',
        'offset' => '',
        'exclusive' => '',
        'finderQuery' => '',
        'counterQuery' => ''
    )
  );
}

It’s a Cake convention to have pluralised controllers (CarsController, GenresController) and singular models (Car, Genre). When defining associations you’re in essence linking models together and not controllers, hence the need for singular, capitalised classnames.
