Question

我已经关注了CakePHP的教程，并为一个数据库表生成了一个控制器，一个视图和一个模型。我还实现了在数据库中插入新值的add方法，一切正常。现在，我尝试使用蛋糕烘焙来做同样的事情，并且在使用基本的crud方法自动生成控制器后，我仍然无法添加行。这是生成的代码：

class Admin extends AppModel {

/**
 * Primary key field
 *
 * @var string
 */
public $primaryKey = 'username';

/**
 * Display field
 *
 * @var string
 */
public $displayField = 'username';

/**
 * Validation rules
 *
 * @var array
 */
public $validate = array(
    'username' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
            'message' => 'insert username',
            'allowEmpty' => false
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'alphaNumeric' => array(
            'rule' => array('alphaNumeric'),
        //'message' => 'too long',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'isUnique' => array(
            'rule' => 'isUnique',
            'message' => 'This username has already been taken.'
        ),
        'maxLength' => array(
            'rule' => array('maxLength', 50),
            'message' => 'too long',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
    ),
    'password' => array(
        'notEmpty' => array(
            'rule' => array('notEmpty'),
            'message' => 'insert password',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'alphaNumeric' => array(
            'rule' => array('alphaNumeric'),
        //'message' => 'Your custom message here',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
        'maxLength' => array(
            'rule' => array('maxLength', 50),
            'message' => 'max lenght',
        //'allowEmpty' => false,
        //'required' => false,
        //'last' => false, // Stop validation after this rule
        //'on' => 'create', // Limit validation to 'create' or 'update' operations
        ),
    ),
);
}

}

这很简单，添加View：

echo $this->Form->create(array('type' => 'post'));
echo $this->Form->input('username', array('label' => 'username', 'type' => 'text'));
echo $this->Form->input('password');
echo $this->Form->end('Save admin');

现在，当我尝试调用

时

/admin/add

对于show输入表单，我收到此错误消息：

错误：找不到AdminAddController。错误：创建类下面的AddController在文件中：app \ Controller \ AddController.php

出了什么问题？

Answer 1

您应始终将控制器名称复数形式为：

AdminsController

并像/admins/add一样打电话。这是基本的cakePHP步骤。阅读cakePHP烹饪书。

Answer 2

在cakephp中，控制器名称总是复数，模型名称是单数，数据库表名称是复数，例如您的表格是admins＆amp;型号名称必须为Admin。控制器名称AdminsController与camel cap和管理员端，必须添加Controller，因为AdminsController继承了AppController类的属性你应该在你的控制器中写这个

class AdminsController extends AppController {
/* your action */
}

和您的地址栏

/Admins/add

CakePHP控制器方法：无法调用它
