未定义的索引“counterCache”CakePHP

标签: php cakephp methods model

我正在为一个项目做一个简单的任务。 它按预期工作,但在我的Contact Model上使用find方法之后(第二个if),它会抛出一个通知:undefined index "counterCache"。我想修复此通知以防止将来发生崩溃。 我理解我的代码很乱并且没有完美实现(我不得不更新模型,我不能改变所有连接的方式)。

我阅读了CakePHP的API手册,但我似乎不明白发生了什么。我该如何解决此通知?

注意:

Notice (8): Undefined index: counterCache [CORE/Cake/Model/Model.php, line 2109]
Notice (8): Undefined index: counterCache [CORE/Cake/Model/Model.php, line 2109]

代码:

public function confirm($request_id = null, $contact_that_wants_to_add_you_id = null, $confirm = 0){
    $this->layout = 'dashboard';
    $this->User->hasMany=$this->User->belongsTo=$this->User->hasManyAndBelongsTo=array();
    $this->Contact->hasMany=$this->Contact->belongsTo=$this->Contact->hasManyAndBelongsTo=array();
    $this->Contact->belongsTo = array(
        'User' => array(
            'className' => 'User',
            'foreignKey' => 'user_id'
    ));
    $requests = $this->Contact->find('all', array(
        'conditions' => array(
            'Contact.id' => $request_id
        )
    ));
    $exists = $this->Contact->find('count', array(
        'conditions' => array(
            'Contact.user_id' => $this->Auth->user('id'),
            'Contact.contact_id' => $contact_that_wants_to_add_you_id
        )
    ));
    $confirm_contact = $this->Contact->find('first', array(
        'conditions' => array(
            'Contact.id' => $request_id,
            'Contact.user_id' => $contact_that_wants_to_add_you_id,
            'Contact.contact_id' => $this->Auth->user('id')
        )
    ));

    if($exists == 0 && $confirm == 1){

        $exists = $confirm_contact;
        $exists['Contact']['id'] = null;
        $exists['Contact']['user_id'] = $this->Auth->user('id');
        $exists['Contact']['contact_id'] = $contact_that_wants_to_add_you_id;
        $exists['Contact']['friend'] = 1;
        $exists['Contact']['confirmed'] = 1;
        $confirm_contact['Contact']['confirmed'] = 1;

        if($this->Contact->save($exists) && $this->Contact->save($confirm_contact)){
            $requests = $this->Contact->find('first', array(
                'conditions' => array(
                    'Contact.id' => $this->Contact->getLastInsertID()
                )
            ));
        }
    }

    $this->set('requests',$requests);
}

更新(固定): 当我重新阅读文档时,解决方案变得非常简单。但是,我仍然不知道为什么会这样,我想知道为什么。如果有人能够回答,请永远感激。

原文:

$this->Contact->belongsTo = array(
    'User' => array(
        'className' => 'User',
        'foreignKey' => 'user_id'
));

修复:

$this->Contact->belongsTo = array(
    'User' => array(
        'className' => 'User',
        'foreignKey' => 'user_id',
        'counterCache' => false
));

您正在错误地设置关联,只能在构建时初始化模型之前使用模型属性。

在此之后您应该使用Model::bindModel(),否则关联将缺少默认选项,例如counterCache,这可能会导致您遇到的错误等错误。

$this->Contact->bindModel(
    array(
        'belongsTo' => array(
            'User' => array(
                'className' => '...',
                'foreignKey' => '...',
                // ...
            )
        )
    ),
    false
);
