Trying to save a hasMany array from multiple select

问题

I'm trying to save a data from a multiple select. This data is relacioned where "Request" hasMany "Requestc". The foriegnKey is "request_id"

My Controller:

if ($this->request->is('post')) {

    $solicitacao = $this->Request->save($this->request->data['Request']);

    //Verifica se a request foi salva e se sim, salva quais as certidões foram pedidas na tabela requests_certidoes
    if(!empty($solicitacao)) {
        $this->request->data['Requestc']['request_id'] = $this->Request->id;
    //  debug($this->request->data);

        $this->Request->Requestc->saveAll($this->request->data);
    }
}

This is my data from $this->request->data:

array(
'Request' => array(
    'motivo' => 'Licitação',
    'nome_licitacao' => '',
    'data_pregao' => '',
    'nome_cliente' => '',
    'outros' => ''
),
'Requestc' => array(
    'caminho' => array(
        (int) 0 => '1',
        (int) 1 => '3'
    ),
    'request_id' => '60'
)

)

And that's the error:

Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Array' in 'field list'

SQL Query: INSERT INTO societario.requests_certidoes (caminho, request_id) VALUES (Array, 62)

Thanks for all

You need to modify the posted data so that it looks like this:

array(
    'Request' => array(
        'motivo' => 'Licitação',
        'nome_licitacao' => '',
        'data_pregao' => '',
        'nome_cliente' => '',
        'outros' => ''
    ),
    'Requestc' => array(
        0 => array(
            'caminho' => '1',
            // --> optionally add your request_id here
            //     if you're manually saving Requestc
            //     AFTER saving Request
        ),
        1 => array(
            'caminho' => '3',
        )
    )
)

If your relations are properly set-up, you probably don't have to add request_id;

$data = array(
    'Request' => $this->request->data['Request'],
    'Requestc' => array();
);

foreach($this->request->data['Requestc']['caminho'] as $val) {
    $data['Requestc'][] = array(
        'caminho' => $val,

        // Should NOT be nescessary when using the saveAssociated()
        // as below
        //'request_id' => $this->Request->id;
    );
}

// This should insert both the Request *and* the Requestc records
$this->Request->saveAssociated($data);

See the documentation: Saving Related Model Data (hasOne, hasMany, belongsTo)

However, if Requestc.caminho stores the id of Certificates, this seems to be a HABTM relation; Request --> HABTM --> Certificate, in which case the join-table should be called certificates_requests and contain the columns request_id and certificate_id. See the Model and Database Conventions
