Я попытался установить переменную Field на оценкеМодель:
var $virtualFields = array('total' => 'SUM(EstimateDetail.qty*EstimateDetail.Item.weight*EstimateDetail.Item.price)');
Мой Index.ctp:
<tr>
<th><?php echo $this->Paginator->sort('id');?></th>
<th><?php echo $this->Paginator->sort('name');?></th>
<th><?php echo $this->Paginator->sort('employee');?></th>
<th><?php echo $this->Paginator->sort('created');?></th>
<th><?php echo $this->Paginator->sort('modified');?></th>
<th class="actions"><?php __('Actions');?></th>
</tr>
<?php
$i = 0;
foreach ($estimates as $estimate):
$class = null;
if ($i++ % 2 == 0) {
$class = ' class="altrow"';
}
?>
<tr<?php echo $class;?>>
<td><?php echo $estimate['Estimate']['id']; ?> </td>
<td><?php echo $estimate['Estimate']['name']; ?> </td>
<td>
<?php echo $this->Html->link($estimate['Employee']['fullname'], array('controller' => 'employees', 'action' => 'view', $estimate['Employee']['id'])); ?>
</td>
<td><?php echo $estimate['Estimate']['created']; ?> </td>
<td class="actions">
<?php echo $this->Html->link(__('View', true), array('action' => 'view', $estimate['Estimate']['id'])); ?>
<?php echo $this->Html->link(__('Edit', true), array('action' => 'edit', $estimate['Estimate']['id'])); ?>
<?php echo $this->Html->link(__('Delete', true), array('action' => 'delete', $estimate['Estimate']['id']), null, sprintf(__('Are you sure you want to delete # %s?', true), $estimate['Estimate']['id'])); ?>
</td>
</tr>
, и я получаю сообщение об ошибке.
Полученная ошибка:
Warning (2): Invalid argument supplied for foreach() [APP/views/estimates/index.ctp, line 15]
и Sql:
1054: Unknown column 'EstimateDetail.qty' in 'field list
Пожалуйста, помогите.
