CakePHP 3：returns 即使数据未从数据库中获取也是如此

Question

我正在使用 CakePHP 3.2。有一个 table user_addresses 我试图从中获取用户的所有记录

public function myFun()
{
    $this->loadModel('UserAddresses');
    $user_id = $this->Auth->user('id');
    $userAddresses = $this->UserAddresses->find('all', [
       'conditions' => [
           'user_id' => $user_id
       ]
    ]);
    if (empty($userAddresses)) {
       echo 'Hello';               // for testing only
    } else {
       echo 'World';
    }
}

为了检查它，我将 myFun 添加到控制器的 beforeFilter

$this->Auth->allow(['myFun']);

这会打印 World 而不是 Hello 因为没有从数据库检索数据，因为如果用户未登录则 $user_id 必须为空。

Answer 1

首先检查$user_id是否可用然后调用find()方法。

public function myFun()
{
    $this->loadModel('UserAddresses');
    $user_id = $this->Auth->user('id');
    if(empty($user_id)){
        echo "Not able to access this method";
        die();
    }
    $userAddresses = $this->UserAddresses->find('all', [
       'conditions' => [
           'user_id' => $user_id
       ]
    ]);
    if (empty($userAddresses)) {
       echo 'Hello';               // for testing only
    } else {
       echo 'World';
    }
}
