Cakephp3 HABTM error inserting data into table

Question

I am with the error Cannot Insert Row in "addresses_companies" table, it has no Primary key in my application, after entering a company and filling in the address data and selecting a company appears the error quoted above.

Follows code:

Addressescontroller.php

public function add()
{
    $address = $this->Addresses->newEntity();

    if ($this->request->is('post')) {
        $address = $this->Addresses->patchEntity($address, $this->request->data, ['associated' => ['Companies']]);
        if ($this->Addresses->save($address)) {
            $this->Flash->success(__('The address has been saved.'));
            return $this->redirect(['action' => 'index']);
        } else {
            $this->Flash->error(__('The address could not be saved. Please, try again.'));
        }
    }
    $companies = $this->Addresses->Companies->find('list', ['limit' => 200]);
    $this->set(compact('address', 'companies'));
    $this->set('_serialize', ['address']);
}

Address

use Cake\ORM\Entity;

/**
 * Address Entity.
 */
class Address extends Entity
{

/**
 * Fields that can be mass assigned using newEntity() or patchEntity().
 *
 * @var array
 */
   protected $_accessible = [
    'CEP' => true,
    'ENDERECO' => true,
    'BAIRRO' => true,
    'CIDADE' => true,
    'ESTADO' => true,
    'UF' => true,
    'companies' => true,
    'addresses_companies' => true,
   ];
}

    return $validator;

}

add.ctp

<div class="addresses form large-10 medium-9 columns">
<?= $this->Form->create($address) ?>
<fieldset>
    <legend><?= __('Add Address') ?></legend>
    <?php
        echo $this->Form->input('CEP');
        echo $this->Form->input('ENDERECO');
        echo $this->Form->input('BAIRRO');
        echo $this->Form->input('CIDADE');
        echo $this->Form->input('ESTADO');
        echo $this->Form->input('UF');
        echo $this->Form->input('companies._ids', ['options' => $companies]);
    ?>
    </fieldset>
       <?= $this->Form->button(__('Submit')) ?>
       <?= $this->Form->end() ?>
</div>

I want to understand what’s missing, because I can’t find examples on the Internet and the one found on the Cakephp website doesn’t help me.

Answer 1

I solved the problem by adding them as Primary key, but now I came up with the following phrase.

Cannot Insert Row, some of the Primary key values are Missing. Got (, )

Can someone help me solve this problem?
