множественный выбор для ассоциации hasMany в CakePHP 3

У меня есть две таблицы seller_businesses и seller_business_categories. и их ассоциация следующая

SellerBusinessesTable.php

    $this->hasMany('SellerBusinessCategories', [
        'foreignKey' => 'seller_business_id'
    ]);

SellerBusinessCategories.php

$this->belongsTo('SellerBusinesses', [
    'foreignKey' => 'seller_business_id',
    'joinType' => 'INNER'
]);

Я использую одну форму для сохранения данных в обеих таблицах

<?= $this->Form->create($sellerBusiness, ['type' => 'file']) ?>
<?= $this->Form->input('company_name') ?>
<?= $this->Form->input('proof', ['type' => 'file']) ?>
<?= $this->Form->input('seller_business_categories._category_ids', ['multiple' => true, 'options' => $categories]) ?>
<?= $this->Form->button('submit', ['type' => 'submit']) ?>
<?= $this->Form->end() ?>

И действие контроллера

$sellerBusiness = $this->SellerBusinesses->newEntity();
if ($this->request->is('post')) {
  $sellerBusiness->seller_id = $this->Auth->user('id');
  $sellerBusiness = $this->SellerBusinesses->patchEntity($sellerBusiness, $this->request->data, [
   'associated' => [
      'SellerBusinessCategories'
   ]
 ]);
 debug($sellerBusiness);
 if ($save_s_b = $this->SellerBusinesses->save($sellerBusiness)) {
    debug($save_s_b);
    $this->Flash->success(__('The seller business has been saved.'));

    return $this->redirect(['controller' => 'SellerBusinesses', 'action' => 'view', $save_s_b->id]);
  } else {
    $this->Flash->error(__('The seller business could not be saved. Please, try again.'));
  }
}

Но это не сохранение записи в таблицу seller_business_categories.

Из документа здесь

// Multiple select element for belongsToMany
echo $this->Form->input('tags._ids', [
    'type' => 'select',
    'multiple' => true,
    'options' => $tagList,
]);

Но это не работает. Есть ли другой способ для hasMany

debug($this->request->data); дает

'seller_business_categories' => [
        '_category_ids' => [
            (int) 0 => '1',
            (int) 1 => '2'
        ]
    ],

и debug($sellerBusiness); после patchEntity

object(App\Model\Entity\SellerBusiness) {

    'seller_id' => (int) 16,
    'company_name' => 'My company',
    'seller_business_categories' => [
        (int) 0 => object(App\Model\Entity\SellerBusinessCategory) {

            (int) 0 => '1',
            (int) 1 => '2',
            '[new]' => true,
            '[accessible]' => [
                '*' => true
            ],
            '[dirty]' => [
                (int) 0 => true,
                (int) 1 => true
            ],
            '[original]' => [],
            '[virtual]' => [],
            '[errors]' => [],
            '[invalid]' => [],
            '[repository]' => 'SellerBusinessCategories'

        }
    ],
    '[new]' => true,
    '[accessible]' => [
        '*' => true,
    ],
    '[dirty]' => [
        'seller_id' => true,
        'company_name' => true,
        'seller_business_categories' => true,
    ],
    '[original]' => [],
    '[virtual]' => [],
    '[errors]' => [],
    '[invalid]' => [],
    '[repository]' => 'SellerBusinesses'

}

и ошибка

Error: SQLSTATE[HY000]: 
General error: 1364 Field 'category_id' doesn't have a default value in seller_business_categories table
