Question

当用户查看他们的消息时，我希望将每条消息更新为READ。我这样做是通过将读取字段设置为1 / true。

在我找到之后，saveAll似乎没有更新记录。我不确定我的foreach循环或saveAll的问题，我没有错误。

array(
'Message' => array(
    'id' => '1',
    'message_text' => 'this isi a test messge',
    'book_id' => '2',
    'page_id' => '1',
    'user_id' => '537765a1-d64c-4529-aa09-5af648257ec7',
    'read' => false,
    'modified' => '2014-05-26 22:36:32',
    'created' => '2014-05-26 22:36:32'
),
'Book' => array(
    'id' => '2',
    'user_id' => '537765',
    'title' => 'test book 2',
    'modified' => '2014-05-18 14:47:30',
    'created' => '2014-05-18 14:47:30'
),
)

或者如果有很多消息

array(
(int) 0 => array(
    'Message' => array(
        'id' => '1',
        'message_text' => 'this isi a test messge',
        'book_id' => '2',
        'page_id' => '1',
        'user_id' => '537765a1-d64c-4529-aa09-5af648257ec7',
        'read' => false,
        'modified' => '2014-05-26 22:36:32',
        'created' => '2014-05-26 22:36:32'
    ),
    'Book' => array(
        'id' => '2',
        'user_id' => '537765',
        'title' => 'test book 2',
        'modified' => '2014-05-18 14:47:30',
        'created' => '2014-05-18 14:47:30'
    ),
),
(int) 1 => array(
    'Message' => array(
        'id' => '2',
        'message_text' => 'hguhghu uhghuguhg',
        'book_id' => '0',
        'page_id' => '0',
        'user_id' => '537765a1-d64c-4529-aa09-5af648257ec7',
        'read' => false,
        'modified' => '0000-00-00 00:00:00',
        'created' => '0000-00-00 00:00:00'
    ),
    'Book' => array(
        'id' => null,
        'user_id' => null,
        'title' => null,
        'modified' => null,
        'created' => null
    ),
)
)

我的控制器代码messagesController.php

public function index() {
    $this->Message->recursive = 0;
    $conditions = array(
    'conditions' => array('Message.user_id' => $this->Auth->user('id')),
    );
    $messages = $this->Message->find('all');

    foreach( $messages as $m ):
      $m['Message']['read'] = true;
    endforeach;

    $this->Page->saveAll($messages['Message']);
    $this->set('messages', $messages);
}

对此的另一个小问题是，这会更适合模型吗？每次调用find时，模型都会更新“read”字段。

Answer 1

foreach( $messages as $m ) {
  $m['Message']['read'] = true;
  $this->Page->saveAll($m);
}

cakephp foreach on find和saveAll
