Question

以下链接用于Favors列表！它链接到用户所在的地方，但正在帮助列表中使用。因此，有利于变量。

我有三个模型Users，Places和Favors。用户有很多好处和一个地方，一个好处属于用户。

<?php foreach($favours as $favour): ?>

<p><?php echo $this->Html->link($favour['User']['firstname'] . ' ' . $favour['User']['lastname'], array('controller'=>'users','action'=>'view','userName'=>$favour['User']['username'])); ?> in <?php echo $this->Html->link($favour['Place']['name'], array('controller'=>'places','action'=>'view',$favour['Place']['id'])); ?> asked a favour <?php echo $favour['Favour']['datetime']; ?></p>

<h3><?php echo $this->Html->link($favour['Favour']['title'], array('controller'=>'favours','action'=>'view',$favour['Favour']['id'])); ?></h3>

如果我收到错误消息，说明Place未定义，我该如何显示链接。

这是该列表的控制器操作：

function index()
{
    $favours = $this->paginate();

    if (isset($this->params['requested']))
    {
        return $favours;
    }
    else
    {
        $this->set('favours', $favours);
    }
}

Answer 1

确保在为Favor获取数据时包含Place。

Answer 2

这是你在favours_controller中的样子：

function index(){
    $favours = $this->Favour->find('all');
    $places = $this->Favour->Place->find('all');
    $this->paginate();
    $this->set(compact('users', 'places');
}

这是它在index.ctp中的样子：

<?php foreach($favours as $favour): ?>
<?php echo $this->Html->link($favour['Favour']['username'], array('controller'=>'users','action'=>'view', $favour['Favour']['username'])); ?>
<?php endforeach; ?>
<?php foreach($places as $place): ?>
<?php echo $this->Html->link($place['Place']['place'], array('controller'=>'places','action'=>'view', $place['Place']['place'])); ?>
<?php endforeach; ?>

您可能还需要定义uses变量：

var $uses = array('Place');
