Question

我在蛋糕php中有一个非常简单的连接模型。我遇到了一个错误，其中插入的每个新记录的ID是＆＃34;＆＃34;。

 <?php


 App::uses('AppModel', 'Model');
/**
 * Subscriber Model
 *
 * @property ChallengeMember $ChallengeMember
 * @property Activity $Activity
 */
class Subscriber extends AppModel {


    //The Associations below have been created with all possible keys, those that are not needed can be removed

/**
 * belongsTo associations
 *
 * @var array
 */
    public $belongsTo = array(
        'ChallengeMember' => array(
            'className' => 'ChallengeMember',
            'foreignKey' => 'challenge_member_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        ),
        'Activity' => array(
            'className' => 'Activity',
            'foreignKey' => 'activity_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        )
    );
}

这就是表格的样子：

  public $fields = array(
        'id' => array('type' => 'string', 'null' => false, 'default' => null, 'length' => 36, 'key' => 'primary', 'collate' => 'latin1_swedish_ci', 'charset' => 'latin1'),
        'activity_id' => array('type' => 'string', 'null' => false, 'default' => null, 'length' => 37, 'collate' => 'latin1_swedish_ci', 'charset' => 'latin1'),
        'challenge_member_id' => array('type' => 'string', 'null' => false, 'default' => null, 'length' => 37, 'collate' => 'latin1_swedish_ci', 'charset' => 'latin1'),
        'indexes' => array(

        ),
        'tableParameters' => array('charset' => 'latin1', 'collate' => 'latin1_swedish_ci', 'engine' => 'InnoDB')
    );

测试时，

$this->Subscriber->create(array('challenge_member_id' => 'test123456','ChallengeMember.first_time_in_dash' => '1'));
$this->Subscriber->save();
Debugger::dump($this->Subscriber->find('all'));

输出

array(
        'Subscriber' => array(
            'id' => '',
            'challenge_member_id' => 'test123456',
            'activity_id' => '',
            'created' => '2014-07-16 18:45:14'
        )
        ........

正如你所看到的那样，蛋糕会自动失败，因为这对我的其他模特来说是不合时宜的。有任何想法吗？我重新烘焙了模型和测试夹具，但没有快乐！

好的，所以我从来没有完全理解这个问题，这个问题似乎只与名为＆＃34; Subscriber＆＃34;的表有关。每个其他表都有一个ID字段定义为：

'id' => array('type' => 'string', 'null' => false, 'default' => null, 'length' => 36, 'key' => 'primary', 'collate' => 'latin1_swedish_ci', 'charset' => 'latin1')

在Model :: save（）上，cakephp auto会生成如下所示的ID：

53c4fe0c-c38c-4915-a056-111fd1f54a2f.

最后，我将订阅者ID字段设置为＆＃34; INT（11）自动递增＆＃34;，让mysql负责密钥生成。这解决了这个问题。

Cakephp无法在插入时自动生成记录ID
