刪除用戶無法正常工作

Question

我希望能夠刪除用戶，但是當我嘗試時會引發以下錯誤。 「錯誤：在此服務器上未找到請求的地址'/ cakephp/users/delete/8？url = users％2Fdelete％2F8'。」

我刪除功能的代碼是

public function delete($id = null) 
{ 
     debug($this->User->delete()); 
     if (!$this->request->is('get')) 
     { 
      throw new MethodNotAllowedException(); 
     } 
     if ($this->User->delete($id)) 
     { 
      $this->Session->setFlash('The user with id: ' . $id . ' has been deleted.'); 
      $this->redirect(array('action' => 'usermanage')); 
     } 
    } 

[NEW] 我擺脫了usermanagement代碼和索引碼，以騰出空間給我的用戶模式代碼..

<?php 
App::uses('AuthComponent', 'Controller/Component'); 
class User extends AppModel { 

    public $primary_key = 'userID'; 
    public $validate = array(
     'username' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'A username is required' 
      ) 
     ), 

     'password' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'A password is required' 
      ) 
     ), 
     'name' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'Your name is required' 
      ) 
     ), 
     'surname' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'Your surname is required' 
      ) 
     ), 
     'memberType' => array(
      'valid' => array(
       'rule' => array('inList', array('admin', 'responder', 'volunteer')), 
       'message' => 'Please enter a valid role', 
       'allowEmpty' => false 
      ) 
     ), 
     'address1' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'Please enter your first line of address' 
      ) 
     ), 
     'address2' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'please enter your second line of address' 
      ) 
     ), 
     'town' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'Please enter your town' 
      ) 
     ), 
     'postCode' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'please enter your postcode' 
      ) 
     ), 
     'dob' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'please enter your date of birth' 
      ) 
     ), 
     'emailAddress' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'please enter your email address' 
      ) 
     ), 
     'phoneNumber' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'please enter your phone number' 
      ) 
     ), 
     'mobileNumber' => array(
      'required' => array(
       'rule' => array('notEmpty'), 
       'message' => 'please enter your mobile number' 
      ) 
     ) 
    ); 

    public function beforeSave($options = array()) { 
     if (isset($this->data[$this->alias]['password'])) { 
      $this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']); 
     } 
    } 
} 
?> 

任何幫助將不勝感激！

這個錯誤可以通過兩種方式（皮卡之一）進行修正：

1 - 改變你的行動上刪除對：

if (!$this->request->is('post') && !$this->request->is('put')) { 
    throw new MethodNotAllowedException(); 
} 

2 - 不使用postLink，並更改刪除操作：

<?php echo $this->Html->link('Delete', array('controller' => 'users', 'action' => 'delete', $user['User']['userID'])); ?> 

public function delete($id = null) { 
     $this->User->id = $id; 

     if(!$this->User->exists()) { 
      throw new NotFoundException(__('Invalid user')); 
     } 

     if ($this->User->delete($id)) { 
      $this->Session->setFlash('The user with id: ' . $id . ' has been deleted.'); 
      $this->redirect(array('action' => 'usermanage')); 
     } 
} 

[編輯]
爲了您的PrimaryKey問題：
在用戶模式：

public $primary_key = 'userID'; 

在其它型號（屬於關聯，的hasMany，hasBelongsToMany）：

public $belongsTo = array(
    'User' => array(
     'className' => 'User', 
     'foreignKey' => 'userID' 
    ) 
);
