使用cakephp在index()中显示来自两个不同表的数据。 [英] Display data from two different tables in the index() using cakephp.
问题描述
我创建了一个表单,我需要显示一个表,其中的数据来自两个不同的表。数据来自分支表。这个分支表包含一个外键PrimaryContactID(int),它将包含Employee表的主键。
I've created a form where I need to display a table for which the data is coming from two different tables. The data is coming from Branch table. This Branch table contains a foreign key PrimaryContactID(int) which will contain the primary key of Employee table.
现在,在索引页中,我显示了所有的细节分支表,除了PrimaryContactID。而不是我需要显示从该表的名称。这是我的尝试:
Now, in the index page I have display all the details from the Branch table, except for the PrimaryContactID. Instead of that I need to display the names from that table. This is how I tried:
controller:
public function index()
{
$branch = $this->paginate($this->Branch);
$this->set(compact('branch'));
$this->set('_serialize', ['branch']);
}
index.ctp:
<div class="branch index large-9 medium-8 columns content">
<h3><?= __('Branch') ?></h3>
<table cellpadding="0" cellspacing="0">
<thead>
<tr>
<th><?= $this->Paginator->sort('BranchID') ?></th>
<th><?= $this->Paginator->sort('BranchName') ?></th>
<th><?= $this->Paginator->sort('BranchCode') ?></th>
<th><?= $this->Paginator->sort('Telephone') ?></th>
<th><?= $this->Paginator->sort('PrimaryContactID') ?></th>
<th class="actions"><?= __('Actions') ?></th>
</tr>
</thead>
<tbody>
<?php foreach ($branch as $branch): ?>
<tr>
<td><?= $this->Number->format($branch->BranchID) ?></td>
<td><?= h($branch->BranchName) ?></td>
<td><?= h($branch->BranchCode) ?></td>
<td><?= h($branch->Telephone) ?></td>
<td><?= $this->Number->format($branch->PrimaryContactID) ?></td>
<td class="actions">
<?= $this->Html->link(__('View'), ['action' => 'view', $branch->BranchID]) ?>
<?= $this->Html->link(__('Edit'), ['action' => 'edit', $branch->BranchID]) ?>
<?= $this->Form->postLink(__('Delete'), ['action' => 'delete', $branch->BranchID], ['confirm' => __('Are you sure you want to delete # {0}?', $branch->BranchID)]) ?>
</td>
</tr>
<?php endforeach; ?>
</tbody>
</table>
<div class="paginator">
<ul class="pagination">
<?= $this->Paginator->prev('< ' . __('previous')) ?>
<?= $this->Paginator->numbers() ?>
<?= $this->Paginator->next(__('next') . ' >') ?>
</ul>
<p><?= $this->Paginator->counter() ?></p>
</div>
</div>
通过使用上述方法,我可以检索PrimaryContactID(int)。但是,而不是我需要从Employee表中获取名称。我不知道该怎么做。可以有人说我应该改变什么,这样我会得到名字?
By using the above method, I could retrieve the PrimaryContactID(int). But, instead of that I need to get the name from the Employee table. I don't know how to do that. Can some one say what should I change, so that I would get the name?
推荐答案
:
$this->paginate = [
'contain' => ['Employee'] // Employees?
];
$branch = $this->paginate($this->Branch);
并在您的视图中:
<?= h($branch->employee->name) ?>
