所以我有三个表，用户、组和 users_groups，这是一个连接表。
--
-- Table structure for table `groups`
--
CREATE TABLE `groups` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(50) NOT NULL,
`description` text NOT NULL,
`all_versions_available` tinyint(1) unsigned NOT NULL DEFAULT '1',
`created` datetime NOT NULL,
`modified` datetime NOT NULL,
PRIMARY KEY (`id`),
KEY `name` (`name`,`created`,`modified`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=12 ;
-- --------------------------------------------------------
--
-- Table structure for table `users`
--
CREATE TABLE `users` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`username` varchar(40) NOT NULL,
`email` varchar(80) NOT NULL,
`password` varchar(50) NOT NULL,
`role` varchar(20) NOT NULL,
`created` datetime NOT NULL,
`modified` datetime NOT NULL,
`fullname` varchar(80) NOT NULL,
`password_token` varchar(40) NOT NULL,
PRIMARY KEY (`id`),
KEY `nickname` (`username`,`email`,`password`),
KEY `role` (`role`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=6 ;
-- --------------------------------------------------------
--
-- Table structure for table `users_groups`
--
CREATE TABLE `users_groups` (
`user_id` int(11) unsigned NOT NULL,
`group_id` int(11) unsigned NOT NULL,
KEY `user_id` (`user_id`,`group_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
在我的组和用户模型中实现 HABTM 之前，我下面的代码运行良好，现在，我得到了我需要的所有数据，但我无法保存。
所以，我的组模型看起来像这样：
<?php
class Group extends AppModel {
public $hasAndBelongsToMany = array(
'Application' => array(
'className' => 'Application',
'joinTable' => 'applications_groups',
'foreignKey' => 'group_id',
'associationForeignKey' => 'application_id',
'unique' => 'keepExisting',
),
'User' => array(
'className' => 'User',
'joinTable' => 'users_groups',
'foreignKey' => 'group_id',
'associationForeignKey' => 'user_id',
'unique' => 'keepExisting',
)
);
public $validate = array(
'name' => array(
'required' => array(
'rule' => array('notEmpty'),
'message' => 'Group name is required'
)
)
);
public function saveGroup($id, $name, $description) {
$id = (int)$id;
if ($id) {
$this->id = $id;
}
else {
$this->create();
}
$this->set('name', $name);
$this->set('description', $description);
$this->save();
return $this;
}
public function getAll() {
$options = array('order' => array('Group.name' => 'ASC'));
$data = $this->find('all', $options);
return $data;
}
public function getOne($id) {
$id = (int)$id;
return $this->find('first', array('conditions' => array('Group.id' => $id)));
}
}
我的用户模型如下所示：
<?php
class User extends AppModel {
public $hasAndBelongsToMany = array(
'Group' => array(
'className' => 'Group',
'joinTable' => 'users_groups',
'foreignKey' => 'group_id',
'associationForeignKey' => 'user_id',
'unique' => 'keepExisting',
)
);
public function getOne($id) {
$this->id = $id;
$data = $this->read(null, $id);
unset($data['User']['password']);
unset($data['User']['password_token']);
if (isset($data['User'])) $data['User']['gravatar_url'] = 'http://www.gravatar.com/avatar/'.md5($data['User']['email']).'.jpg';
return $data;
}
private function addGravatars($data) {
foreach ($data as $key=>$user) {
$data[$key]['User']['gravatar_url'] = 'http://www.gravatar.com/avatar/'.md5($user['User']['email']).'.jpg';
}
return $data;
}
public function getAll() {
$data = $this->find('all', array('order' => array('User.fullname' => 'ASC')));
$data = $this->addGravatars($data);
return $data;
}
public function countAll() {
return $this->find('count');
}
}
我一直在为连接表使用模型：
<?php
class UsersGroup extends AppModel {
public function deleteAllWithGroup($groupId) {
$id = (int)$groupId;
return $this->deleteAll(array('UsersGroup.group_id' => $id), false);
}
public function saveUsersForGroup($users, $groupId=0) {
$this->deleteAllWithGroup($groupId);
$data = array();
foreach ($users as $id=>$user) {
$data[] = array('user_id'=>(int)$id, 'group_id'=>$groupId);
}
$this->saveMany($data);
}
}
这是我的组控制器：
<?php
class GroupsController extends AppController {
var $uses = array('Group', 'User', 'UsersGroup');
public function index() {
$this->set('groups', $this->Group->getAllWithInfo());
}
public function edit($id=0) {
$this->set('group', $this->Group->getOne($id));
$this->set('usersList', $this->User->getAllWithGroupInfo($id));
if ($this->request->is('post')) {
$group = $this->Group->saveGroup($this->request->data['id'], $this->request->data['name'], $this->request->data['description']);
// Saving users
if (!isset($this->request->data['user']) || empty($this->request->data['user'])) {
$this->UsersGroup->deleteAllWithGroup($group->id);
}
else $this->UsersGroup->saveUsersForGroup($this->request->data['user'], $group->id);
}
}
public function view($id) {
App::uses('Platforms', 'Lib/Platform');
$this->setPageIcon('group');
$this->set('group', $this->Group->getOne($id));
}
public function delete($id) {
$this->Group->delete((int)$id);
return $this->redirect(array('action' => 'index'));
}
}
有几个问题，如果我删除 HABTM 配置，上面的系统可以工作，第二，我没有，由于一些非常具体的原因，不使用表单助手来生成表单，不幸的是代码的复杂性（这是只是一点点）我不能，所以我必须自己手动命名所有内容（这是我看到最大的失败可能性的地方），最后当我现在触发这段代码时，我得到：
Database Error
Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'deleteAllWithGroup' at line 1
SQL Query: deleteAllWithGroup
Notice: If you want to customize this error message, create app/View/Errors/pdo_error.ctp
所以用户组模型没有被注册，当我删除文件时没有任何变化，它试图使用我以前用来删除旧连接数据的方法的名称作为 SQL 命令。我已经尝试了所有可能的建议来命名我在 Stack 上找到的数据的结构和结构，但失败了，我得到的最远的是当我只有一个要保存的连接项时，总是数组中的最后一个......
任何人都可以帮助解决这个问题吗？
干杯，
O。
