Zend Framework 和嵌套集

发布于 2024-12-18 17:13:58 字数 1070 浏览 2 评论 0原文

我们目前正在基于 Zend Framework 开发自己的 ShopProducts Feedmanager。在此 feedmanager 中，您可以管理多个要创建并发送到不同位置的 feed。每个提要都有 n 个字段，这些字段在当前版本中仅存在于一个级别中。现在我们想将其更改为多级版本，我们有父字段和子字段。

我们不想重新发明轮子，所以我们想使用开发的类或助手。

我找到了 F. Pietka 的班级。 https://github.com/fpietka/Zend-Nested-Set 我尝试在我们的系统中使用这个助手，但没有成功。

我编写了以下行来使用该类：

$oNested = new NestedSet_Model();

我收到以下错误消息：

致命错误：调用未定义的方法 NestedSet_Model::getDbTable() D:\xampp\htdocs\feedmanager_alpha\application\classes\NestedSet.class.php 第75行

Peitka 的 NestedSet 帮助程序的自述文件中，它说 ZendLibrary 需要位于包含路径中。

我想我是用以下几行做到的：

define("ROOTPATH", realpath("../"));
define("LIBPATH", ROOTPATH . DIRECTORY_SEPARATOR . 'library' . DIRECTORY_SEPARATOR);

// Ensure library/ is on include_path
set_include_path(
    implode(PATH_SEPARATOR,
        array(
            realpath(LIBPATH)
        )
    )
);

我是否正确设置了包含路径？我的情况可能是什么问题？嵌套集是创建父子模型的最佳方式吗？

we`re currently developing our own Feedmanager for ShopProducts based on Zend Framework.
In this feedmanager you can manage several feeds, to be created and sent to different locations.
Each feed has n-fields which are in the current version only in one level.
Now we want to change it to a multilevel version, we we have parentfields and childfields.

We dont want to reinvent the wheel, so we would like to use a developed class or helper.

I found the class of F. Pietka.
https://github.com/fpietka/Zend-Nested-Set
I tried to use this helper in our system, but had no success.

I wrote the following line, to use the class:

$oNested = new NestedSet_Model();

I got the following error message:

Fatal error: Call to undefined method NestedSet_Model::getDbTable() in
D:\xampp\htdocs\feedmanager_alpha\application\classes\NestedSet.class.php
on line 75

In the readme of Peitka`s NestedSet helper it says that the ZendLibrary needs to be in the include path.

I think I did this with the following lines:

define("ROOTPATH", realpath("../"));
define("LIBPATH", ROOTPATH . DIRECTORY_SEPARATOR . 'library' . DIRECTORY_SEPARATOR);

// Ensure library/ is on include_path
set_include_path(
    implode(PATH_SEPARATOR,
        array(
            realpath(LIBPATH)
        )
    )
);

Did I set the include path correctly?
What could be the problem in my case?
Is a nested-set the best way to create the parent-child-model?

我强烈建议你不要使用这个类，因为它显然是一个 WIP。但是，如果您想避免此错误，只需删除 __construct() 方法并手动调用 setDb() 和 setTableName() 即可。

例子：

$model = new NestedSet_Model();
$model->setDb(Zend_Db_Table::getDefaultAdapter());
$model->setTableName('table_name');

I would strongly advise you not to use this class, because it's clearly a WIP. However, if you want to circumvent this error, you can just delete the __construct() method and call the setDb() and setTableName() by hand.

Example:

$model = new NestedSet_Model();
$model->setDb(Zend_Db_Table::getDefaultAdapter());
$model->setTableName('table_name');

class NestedSet extends Zend_Db_Table
{
    protected $_name = 't_nested_set_mkb_10';

    public function set(){
        $model = new NestedSet_Model();
        $model->setDb(Zend_Db_Table::getDefaultAdapter());
        $model->setTableName('t_nested_set_mkb_10');
    }
}

class NestedSet extends Zend_Db_Table
{
    protected $_name = 't_nested_set_mkb_10';

    public function set(){
        $model = new NestedSet_Model();
        $model->setDb(Zend_Db_Table::getDefaultAdapter());
        $model->setTableName('t_nested_set_mkb_10');
    }
}
