CakePHP 在非对象上调用成员函数 disable()

Question

以前从未使用过 cakephp，我们有一个项目要为我们的客户在 cakephp 2.5 中编辑。

我们尝试创建一个新功能“Emmplois”来在网站内添加工作。我们主要从网站内已经运行的其他模型/控制器重新创建存在的内容，但目前我们收到此错误，我们无法解决问题。

Error: Call to a member function disable() on a non-object
File: /home/voyou/subdomains/labsurface/app/Controller/EmploisController.php
Line: 95

这是模型： /app/Model/Emploi.php

<?php
App::uses('AppModel', 'Model');
/**
 * Emploi Model
 *
 */
class Emploi extends AppModel {

public $faIcone = "thumb-tack";
public $order = 'Emploi.ordre';


public $actsAs = array(
        'I18n' => array(
            'fields' => array('nom')
        ),
    );
/**
 * Display field
 *
 * @var string
 */
    public $displayField = 'nom_fre';
/**
 * Search field
 *
 * @var string
 */
    public $searchField = 'nom_fre';
}

这是控制器：/app/Controller/EmmploisController.php

        $error = 0;
        Configure::write('debug', 0);
        foreach($_POST['Emplois'] as $pos=>$id) {
            if($id) {
                $data['Emploi']['id'] = $id;
                $data['Emploi']['ordre'] = $pos;
                if (!$this->Emploi->save($data, array('fieldList'=>array('ordre')))) {
                    $error++;
                }
            }
        }
    }
}

错误指向public function admin 内的$this->Emploi->Behaviors->disable('I18n'); 行，但据我们了解，$this->Emploi 为空，我们不知道如何将模型链接到控制器。

Answer 1

正如 cmets 中所提到的，您的代码的问题在于它使用了非美国英语名称，这违反了 CakePHP 的命名约定，并且打破了使用变形来完成诸如查找和加载默认模型等任务的魔力。基于单数化控制器名称的控制器。

变形主要适用于从美国英语单词中得知的词尾，它并不像变形器知道所有可能的单词，它只是一些基本的语法规则和一些例外，所以事情可能适用于其他语言的单词只是因为他们的结局恰好符合规则。 -ois 与您的 Emplois 名称一样，与未变形词的规则相匹配，它会捕获像 bourgeois 或 Illinois 这样的词。关于您在 cmets 中的示例，Projets 和 Projects，变形器没有区别，它不会匹配任何不规则的东西，而只是 -s 结尾规则，因此被解释为复数，所以它恰好可以这么说，只是偶然工作。

理想情况下，您在任何地方都使用正确的英文名称。如果你现在不能解决这个问题，那么下一个最好的办法是使用自定义变形，或者根据变形失败的情况手动干预，比如手动使用loadModel()。 Emploi/Emplois 的自定义变形示例如下：

// in `app/Config/bootstap.php`

Inflector::rules('singular', array(
    'irregular' => array(
        'emplois' => 'emploi',
    ),
));
