使用 CakePHP 为 ACL 接口 (gui) 定义模型关系答案

【问题标题】：Defining Model Relations for ACL Interface (gui) with CakePHP使用 CakePHP 为 ACL 接口 (gui) 定义模型关系

【问题描述】：

我已经在我的 cakePHP 应用上成功设置了 Auth 和 ACL。

如何，现在我想建立一个界面来管理 ACL、ARO 和 ACO

ARO 和 ACO 使用树行为非常容易构建。 ACL 怎么让我有点搞砸了……尤其是在定义模型关系时。

我已将我的 aco 和 aro 模型分别命名为 Myaco 和 Myaro，因为 Aco 和 Aro 已经被 AclComponent 占用。我的 ACL 模型是 Myacl。

Myaco 是一个“独立”对象，它与任何其他模型无关。 Myaro "belongsTo" 'Customer' 模型（这是我的“user”模型）并定义如下：

//Myaro model
var $belongsTo = array('Customer'=> array(
                                        'foreignKey'    => 'foreign_key'
                                        ));

现在我理解的 Myacl 模型是 $hasAndBelongsToMany -> Myaco 和 Myaro，因为它是一个连接其他两个模型的表；因此，我已将其设置为：

class Myacl extends AppModel {
    var $useTable = 'aros_acos';
    var $hasAndBelongsToMany = array(
        'Myaro' => array(
                        'foreignKey' => 'aro_id',
                        'associationForeignKey' => 'id',
                        'joinTable' => 'aros_acos'
                    ),
        'Myaco' => array(
                        'foreignKey' => 'aco_id',
                        'associationForeignKey' => 'id',
                        'joinTable' => 'aros_acos'
                        ),
    );
}

现在要为 ACL 构建主“界面”，我想“查找（'all'）”ACL 记录，并将链接（递归）到“客户”级别 - 这样我就可以显示来自aro 表的组和实际客户；所以我将 Myacl 模型的 recursive 参数设置为“2”

虽然从调试窗格的 SQL 查询来看 - 关系根本不正确.. 我设置关系的方式完全错了吗？

以下是 find('all') 调用中的基本 SQL 查询：

从此代码（在 Myacl 控制器中）：

$this->Myacl->recursive = 2;
$allRules = $this->Myacl->findAll();

查询是：

1   DESCRIBE `aros`     7   7   13
2   DESCRIBE `acos`     7   7   1
3   DESCRIBE `aros_acos`        3   3   1
4   DESCRIBE `customers`        9   9   2
5   SELECT `Myacl`.`id`, `Myacl`.`aro_id`, `Myacl`.`aco_id` FROM `aros_acos` AS `Myacl` WHERE 1 = 1 ORDER BY `Myacl`.`id` ASC       9   9   0

您可以从“客户”查询的数量和连接中看到 - 模型关系严重“偏离”了一些东西..

非常感谢任何建议或线索。谢谢，肯。

【解决方案1】：

我刚从 ACL 开始，但我认为您在 acl 关系中弄错了。 aro hasAndBelongsToMany aco，使 acl 成为它们之间的存根。所以，如果你正在制作一个acl的模型，它应该有一个belongsTo aco和belongsTo aco。 Aro 和 aco 应该有一个 hasMany acl。希望对你有帮助;D

@Ferco：感谢您的回复，有点晚了，但我已经想通了。我按照你的建议做了 - 相同的关系。谢谢！
