我正在尝试遍历模型中的记录并更新它们的序列号。根据 tempArray，所有值都应该按顺序排列，但更新部分没有发生。在模型中使用读取/设置/保存是否有限制，或者我缺少什么？
$tempArray['highest serial'] = $highest['Paragraph']['serial_number'];
for( $i=$paragraph['Paragraph']['serial_number']; $i<$highest['Paragraph']['serial_number']; $i++ ){
$current = $this->find('first', array(
'fields' => array(
'Paragraph.id',
'Paragraph.serial_number'
),
'conditions' => array(
'Paragraph.webpage_id' => $paragraph['Paragraph']['webpage_id'],
'Paragraph.list_element' => $paragraph['Paragraph']['list_element'],
'Paragraph.serial_number' => ($i + 1)
)
));
$tempArray['i ' . $i . ' id'] = $current['Paragraph']['id'];
$tempArray['i ' . $i . ' serial'] = $current['Paragraph']['serial_number'];
$this->create($current);
// $this->read('serial_number', $current['Paragraph']['id']);
// $this->id = $current['Paragraph']['id'];
$this->set('serial_number', $i);
$this->save();
}
return $tempArray;
虽然 tempArray 的输出是( [highest serial] => 2 [i 1 id] => 7 [i 1 serial] => 2 )记录的序列号，id=7但未更新。
救命！
编辑：按照建议将 read() 更改为 create()。没有发生 SQL 或 PHP 错误，并且 tempArray 值正确，但没有更新到数据库记录。任何帮助将不胜感激。
编辑2：它正在工作！最后..由于某种原因，我只能使用 saveField() 让它工作
for( $i=$paragraph['Paragraph']['serial_number']; $i<getHighestSerial($paragraph); $i++ ){
$current = $this->find('first', array(
'fields' => array(
'Paragraph.id',
'Paragraph.serial_number'
),
'conditions' => array(
'Paragraph.webpage_id' => $paragraph['Paragraph']['webpage_id'],
'Paragraph.list_element' => $paragraph['Paragraph']['list_element'],
'Paragraph.serial_number' => ($i + 1)
)
));
$this->id = $current['Paragraph']['id'];
$this->saveField('serial_number', $i);
}
