我正在尝试做的事情：
我想在 Cakephp 中安装Alkemann的 LogableBehavior。
我得到的错误：
当我要进行编辑时，会返回错误：
错误：
注意（8）：未定义变量：logData [APP\Model\Behavior\LogableBehavior.php，第 431 行]
标准 cakephp 错误中给出的上下文：
LogableBehavior::afterSave() - APP\Model\Behavior\LogableBehavior.php，第 431 行 ObjectCollection::trigger() - CORE\Cake\Utility\ObjectCollection.php，第 130 行 call_user_func - [内部]，行 ?? CakeEventManager::dispatch() - CORE\Cake\Event\CakeEventManager.php，第 246 行 Model::save() - CORE\Cake\Model\Model.php，第 1755 行 Model::saveField() - CORE\Cake\Model \Model.php，第 1582 行 ChantiersController::inPlaceDateUpdate() - APP\Controller\ChantiersController.php，第 370 行 ReflectionMethod::invokeArgs() - [内部]，行 ??

标准 cakephp 错误中给出的代码：
$Model = object(Chantier) {}
$created = false
$keys = array(
(int) 0 => 'id',
(int) 1 => 'Date_de_debut_MOA',
(int) 2 => 'modified'
)
$diff = array(
(int) 1 => 'Date_de_debut_MOA',
(int) 2 => 'modified'
)
$id = '126'
我试图做的事情：
我检查了所有正确完成的安装步骤，根据文档有三个：
Requires the following to work as intended :
*
* - "Log" model ( empty but for a order variable [created DESC]
* - "logs" table with these fields required :
* - id [int] :
* - title [string] : automagically filled with the display field of the model that was modified.
* - created [date/datetime] : filled by cake in normal way
*
* - actsAs = array("Logable"); on models that should be logged
在我看来，我做的一切都很好：
我的日志表
CREATE TABLE IF NOT EXISTS `logs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`title` varchar(100) NOT NULL,
`created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`description` varchar(400) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=45 ;
我的日志模型：
<?php
App::uses('AppModel', 'Model');
class Log extends AppModel {
var $order=array("Log.created"=>"DESC");
}
在 App/Model/Chantier 中：
var $actsAs = array('Containable','Logable');
然后我搜索有类似问题的人：
什么也没找到。
让我们深入研究代码：
这是代码。
该错误涉及错误行 431：
$this->_saveLog($Model, $logData); //line 431
似乎 $logData 尚未声明。
这一行在一个函数中，afterSave(&$Model,$created)：
该函数是一系列测试，其中第 431 行称为最后。$logData 有许多声明，但总是嵌套在 if 语句中。
function afterSave(&$Model,$created) {
if (isset($this->settings[$Model->alias]['skip']['add']) && $this->settings[$Model->alias]['skip']['add'] && $created) {
return true;
} elseif (isset($this->settings[$Model->alias]['skip']['edit']) && $this->settings[$Model->alias]['skip']['edit'] && !$created) {
return true;
}
$keys = array_keys($Model->data[$Model->alias]);
$diff = array_diff($keys,$this->settings[$Model->alias]['ignore']);
if (sizeof($diff) == 0 && empty($Model->logableAction)) {
return false;
}
if ($Model->id) {
$id = $Model->id;
} elseif ($Model->insertId) {
$id = $Model->insertId;
}
if (isset($this->Log->_schema[$this->settings[$Model->alias]['foreignKey']])) {
$logData['Log'][$this->settings[$Model->alias]['foreignKey']] = $id;
}
if (isset($this->Log->_schema['description'])) {
$logData['Log']['description'] = $Model->alias.' ';
if (isset($Model->data[$Model->alias][$Model->displayField]) && $Model->displayField != $Model->primaryKey) {
$logData['Log']['description'] .= '"'.$Model->data[$Model->alias][$Model->displayField].'" ';
}
if ($this->settings[$Model->alias]['description_ids']) {
$logData['Log']['description'] .= '('.$id.') ';
}
if ($created) {
$logData['Log']['description'] .= __('added',TRUE);
} else {
$logData['Log']['description'] .= __('updated',TRUE);
}
}
if (isset($this->Log->_schema['action'])) {
if ($created) {
$logData['Log']['action'] = 'add';
} else {
$logData['Log']['action'] = 'edit';
}
}
if (isset($this->Log->_schema['change'])) {
$logData['Log']['change'] = '';
$db_fields = array_keys($Model->_schema);
$changed_fields = array();
foreach ($Model->data[$Model->alias] as $key => $value) {
if (isset($Model->data[$Model->alias][$Model->primaryKey]) && !empty($this->old) && isset($this->old[$Model->alias][$key])) {
$old = $this->old[$Model->alias][$key];
} else {
$old = '';
}
if ($key != 'modified'
&& !in_array($key, $this->settings[$Model->alias]['ignore'])
&& $value != $old && in_array($key,$db_fields) )
{
if ($this->settings[$Model->alias]['change'] == 'full') {
$changed_fields[] = $key . ' ('.$old.') => ('.$value.')';
} else if ($this->settings[$Model->alias]['change'] == 'serialize') {
$changed_fields[$key] = array('old'=>$old, 'value'=>$value);
} else {
$changed_fields[] = $key;
}
}
}
$changes = sizeof($changed_fields);
if ($changes == 0) {
return true;
}
if ($this->settings[$Model->alias]['change'] == 'serialize') {
$logData['Log']['change'] = serialize($changed_fields);
} else {
$logData['Log']['change'] = implode(', ',$changed_fields);
}
$logData['Log']['changes'] = $changes;
}
$this->_saveLog($Model, $logData);//line 431
}
我的问题：
理想情况下，我希望知道此行为的人就如何修复错误提供一些建议，但任何有关如何调试它的通用方法都将被欣然接受。
编辑：我使用 Cakephp 2.2.0
