Cakephp，使用 find 检索 HABTM 模型的数据

发布于 2024-08-25 22:01:11 字数 392 浏览 5 评论 0原文

我是 cakephp 的新手，我正在尝试完成一些应该相对容易的事情。我有 2 个模型项目 &类别通过 HABTM 关系绑定。

我正在尝试执行以下查询 ->查找属于某个类别的所有项目

$projects = $this->Project->find('all', array('conditions' => array('Category.slug' => $category)));

但是，当我这样做时，它会生成 SQL 错误：

SQL Error: 1054: Unknown column 'Category.slug' in 'where clause'

我做错了什么？

I am new to cakephp and I'm trying to accomplish something that should be relatively easy.
I have 2 models projects & categories bind by HABTM relationship.

I am trying to perform the following query -> find all projects that belong to a category

$projects = $this->Project->find('all', array('conditions' => array('Category.slug' => $category)));

However when I'm doing so it generates an SQL error:

SQL Error: 1054: Unknown column 'Category.slug' in 'where clause'

What am I doing wrong?

据我所知，你可以这样得到你想要的：

/*in Project Controller file*/

$categorys = $this->Project->Category->find('all', array('conditions' => array('Category.slug' => $category)));

如果正确设置你的HABTM关系，你可能会得到如下的东西：

Array
(  
    [Category] => Array
    (
        [id] => xxx
        [name] => hello there
        ...
    )

    [Project] => Array
    (
        [0] => Array
            (
                [id] => 123
                [name] => Breakfast
            )
       [1] => Array
            (
                [id] => 124
                [name] => Dessert
            )
       [2] => Array
            (
                [id] => 125
                [name] => Heart Disease
            )
    )
)

这就是你想要的，不是吗？参见在食谱中的 cakephp 中使用 HABTM。

As far as I know,you can get what you want like this:

/*in Project Controller file*/

$categorys = $this->Project->Category->find('all', array('conditions' => array('Category.slug' => $category)));

And you will probably get somethin as follows if set you HABTM relationship correctly:

Array
(  
    [Category] => Array
    (
        [id] => xxx
        [name] => hello there
        ...
    )

    [Project] => Array
    (
        [0] => Array
            (
                [id] => 123
                [name] => Breakfast
            )
       [1] => Array
            (
                [id] => 124
                [name] => Dessert
            )
       [2] => Array
            (
                [id] => 125
                [name] => Heart Disease
            )
    )
)

It's what's you want,isn't it?See work with HABTM in cakephp in the cookbook.
