检查CakePHP3中是否存在记录

Question

在CakePHP 2我总是用来empty检查是否有任何结果.

<?php
$result = $this->Modelname->find('first', ['conditions' => ['field' => 'value'] ] );
if ( empty($result) ) {
// Bad Request
}

在CakePHP 3它看起来很怪异.

$fancyTable = TableRegistry::get('FancyTable');        
$query = $fancyTable->find()->where(['name' => 'fancy', 'active' => 0]);          

if ( 0 === $query->count() ) {
    // Bad Request
}

这是正确的方法吗？

Answer 1

你可以做:

$fancyTable = TableRegistry::get('FancyTable');
$exists = $fancyTable->exists(['name' => 'fancy', 'active' => false]);

Answer 2

使用这样的东西:

if ($query->isEmpty()) {
    // Query or result set is empty
}
