请帮我解决这个问题,非常感谢。
第1部分:数据被更改,我使用[$this->abcModel->save($abc);
],abcTable's
修改的列被更改。===>
正常。
第二部分:数据没有改变,我也希望abcTable's
修改的列被改变,如何处理?(如果给我举个例子,会更好地理解。(
使用版本:cakehp3.3
Cakephp版本:cakehp3.3
$this->Model->touch($data);
[Rf.]https://book.cakephp.org/3.0/en/orm/behaviors/timestamp.html
让我们假设您有一个包含以下字段的表单。
Name: XYZ
Number :077777777
**save** button.
它具有表单操作编辑/更新
情况1:用户进行更改并保存表单。情况2:用户不进行任何更改并保存表单。
在任何一种情况下,都应该调用控制器的编辑(或更新(函数。您的姓名和号码字段将在控制器中可用,可以通过$this->request->getData((方法。理想情况下,时间戳需要两个字段,如下所示:"CREATED_ON"one_answers"UPDATED_ON">
您可以使用您提到的触摸方法,但在理想的情况下,最好将行为写入您的模型。每次创建新记录或更改/保存记录时,它都会更新时间戳。
<?php
namespace AppModelBehavior;
use CakeORMBehaviorTimestampBehavior;
/**
* Modify built in CakePHP's Timestamp class's default config so no configuration is necessary for use in this project.
*/
final class CustomTimestampBehavior extends TimestampBehavior
{
/**
* Default config
*
* These are merged with user-provided config when the behavior is used.
*
* events - an event-name keyed array of which fields to update, and when, for a given event
* possible values for when a field will be updated are "always", "new" or "existing", to set
* the field value always, only when a new record or only when an existing record.
*
* refreshTimestamp - if true (the default) the timestamp used will be the current time when
* the code is executed, to set to an explicit date time value - set refreshTimetamp to false
* and call setTimestamp() on the behavior class before use.
*
* @var array
*/
protected $_defaultConfig = [
'implementedFinders' => [],
'implementedMethods' => [
'timestamp' => 'timestamp',
'touch' => 'touch',
],
'events' => [
'Model.beforeSave' => [
'CREATED_ON' => 'new',
'UPDATED_ON' => 'existing',
]
],
'refreshTimestamp' => true
];
}
并从您的模型表中调用它。如下所示:
public function initialize(array $config)
{
parent::initialize($config);
$this
->addBehavior('CustomTimestamp');
这样,您就不需要每次手动调用$This->model->touch($data(。无论何时创建或保存,行为都会处理它。
