Re: Find and HABTM

My first guess is because the necessary fields required by the contains statement to do the join are not included when specifying the contains clause for Disciplina and DisciplinasEvento.

i.e. the query cant get DisciplinasEvento if Disciplina.id is not retrieved.  The query can't get Modalidad if DisciplinasEvento.modalidad_id is not retrieved.

Take a look at the SQL generated via DebugKit or sql_dump to see what fields have been retrieved.

Hi, now I'm trying to retrieve data using find function like this

$this->Evento->Behaviors->load('Containable');

$this->Evento->recursive = -1;

debug($this->Evento->find('all', array('conditions' => array('Evento.id'=>$this->Convert->decode($evento_id)),

'contain' =>array(

'Caracteristica'=>array('fields'=>array(

                                                                         'activar_foto',

 'activar_grupo',

 'activar_menor',

 'activar_limite',

 'activar_personal'

)

),

'Disciplina'=>array(

'DisciplinasEvento'=>array(

'Modalidad'

)

) ),

           )

)

                                         );

this are my linked models

class Evento extends AppModel {

public $hasOne = array(

       'Caracteristica' => array(

           'className'  => 'Caracteristica',

'foreignKey' => 'evento_id'

        )

    );

   public $hasAndBelongsToMany = array(

        'Disciplina' =>

            array(

                'className' => 'Disciplina',

                'joinTable' => 'disciplinas_eventos',

                'foreignKey'=> 'evento_id',

                'associationForeignKey' => 'disciplina_id',

                'unique' => 'keepExisting',

'with' => 'DisciplinasEvento'

            )

    );

}

class DisciplinasEvento extends AppModel {

public $belongsTo = array(

'Evento' => array(

'className' => 'Evento',

'foreignKey' => 'evento_id',

'conditions' => '',

'fields' => '',

'order' => ''

),

'Disciplina' => array(

'className' => 'Disciplina',

'foreignKey' => 'disciplina_id',

'conditions' => '',

'fields' => '',

'order' => ''

),

'Modalidad' => array(

'className' => 'Modalidad',

'foreignKey' => 'modalidad_id',

'conditions' => '',

'fields' => '',

'order' => ''

),

    );

}

class Modalidad extends AppModel {

public $hasMany = array(

'DisciplinasEvento' => array(

'className' => 'DisciplinasEvento',

'foreignKey' => 'modalidad_id'

)

);

}

Question: Why the find function is not retrieving Modalidad data? many thanks
