我正在使用cakephp 2.6.7。我有一个名为＆＃39;客户＆＃39;电子邮件是＆＃39;没有＆＃39;作为表结构的默认值。我重复它默认不是NULL。因此，当电子邮件字段为空时，此字段不会设置为空。在这种情况下，如何检索非空的所有数据。我试过这个：
$customers = $this->Customer->find('list',
array('fields' => array('email'),
'conditions' => array('event_id' => $this->request->data['Product']['event_id'],
'not' => array('Customer.email' => null)
)
)
);
print_r($customers);给出以下结果：
Array

合乎逻辑的是，当没有提供电子邮件的值时，电子邮件字段不为空，但我试图过滤此空值，告知为NOT NULL。有什么方法可以解决这个问题吗？
