CakePHP：在链接表中显示名称而不是 id

Question

我是 CakePHP 和 PHP 的新开发人员。

我有 2 个表：Tasks、Users 和 Customers。

除其他外，Tasks 有这个外键链接到 Users 表：Assigned_from 和外键 Customer_id 链接到 Customers 表。

所以我在UsersTable.php 中插入了这些行：

---

函数初始化：

$this->hasMany('TasksFrom', [
            'foreignKey' => 'assigned_From',
            'className' => 'Tasks'
        ]);

函数构建规则：

$rules->add($rules->existsIn(['assigned_from'], 'TasksFrom'));

---

相应地在 TasksTable.php 中： 函数初始化：

$this->belongsTo('UsersFrom', [
        'foreignKey' => 'assigned_from',
        'className' => 'Users'
    ]);

函数构建规则：

$rules->add($rules->existsIn(['assigned_from'], 'UsersFrom'));

---

在CustomersTable.php中：

函数初始化：

$this->hasMany('Tasks', [
            'foreignKey' => 'customer_id'
        ]);

所以为了在用户视图中显示这些信息，我在 UsersController.php 中添加了这些行：

public function view($id = null)
{
    $user = $this->Users->get($id,[
        'contain' => ['TasksTo', 'TasksFrom', 'TasksBy']
    ]); 
    $this->set('user', $user);
}

如何修改我的代码以便在访问 echo $task->assigned_from 时显示用户名而不是用户 ID 以及在访问 echo $task->customer_id 时显示客户名而不是 Customer_id？

这是 users/view.ctp 中的当前代码：

foreach ($user->tasks_to as $task) {


            ?>
                <tr  id="<?php echo $task['id'] ?>">
                    <td><?php echo $task->priority ?></td>
                    <td><?php echo $task->name ?></td>
                    <td><?php echo $task->instructions ?></td>
                    <td><?php echo $task->assigned_from ?></td>   //It displays user id, I want to display user name
                    <td><?php echo $task->customer_id ?></td>     //Display Customer name instead of Customer_id
                    <td><?php echo $task->progress ?></td>                            
                </tr>
            <?php } ?>

调试输出 debug($user->tasks_to)：

(int) 1 => object(App\Model\Entity\Task) {

        'id' => (int) 2,
        'name' => 'Design Logo for Website',

Answer 1

<td><?php echo $task->assigned_from ?></td>   
//It displays user id, I want to display user name

类似：

<?= $task->users_from->name ?>

和

<td><?php echo $task->customer_id ?></td>
//Display Customer name instead of Customer_id

喜欢：

<?= $task->customers->name ?>
