Cakephp，使用条件查找检索 HABTM 模型的数据

发布于 2024-08-26 12:16:36 字数 292 浏览 6 评论 0原文

有 2 种模型：项目和项目与HABTM关系绑定的类别。我想从可以执行以下操作的项目控制器执行搜索：

FIND all DISTINCT Project.scedule WHERE Category.slug != 'uncategorised'

对语法表示歉意，我不是续集专家。

我设法做的是检索所有不属于的项目到未分类到数组中的类别，但是我不确定如何再次搜索 DISTINCT Project.schedule 值的数组结果（需要填写下拉表单）

原文

There are 2 Models: Project & Category that are bind with HABTM relationship.
I would like to perform a search from projects controller that can do the following:

FIND all DISTINCT Project.scedule WHERE Category.slug != 'uncategorised'

Apologies for the syntax, I'm no sequel expert.

What I have managed to do is to retrieve all projects that do not belong to Category uncategorised into an array however I'm not sure as to how to search again the array result for DISTINCT Project.schedule values (needed to fill out a form drop down)

在回答这个问题之前，我再次建议您阅读CAKEPHP Cookbook中的HABTM 小心点，这样你就可以自己完成这样的工作了。

$this->Project->bindModel(array(
'hasOne' => array(
    'CategorysProject',
    'FilterCategory' => array(
        'className' => 'Category',
        'foreignKey' => false,
        'conditions' => array('FilterCategory.id = CategorysProject.category_id')
))));
$this->Project->find('all', array(
    'fields' => array(DISTINCT (Project.scedule)),
    'conditions'=>array('FilterCategory.slug !='=>'uncategorised')
));

Before answer this question,again I suggest you to read the HABTM in cookbook of CAKEPHP carefully,then you can finish jobs like this yourself.

$this->Project->bindModel(array(
'hasOne' => array(
    'CategorysProject',
    'FilterCategory' => array(
        'className' => 'Category',
        'foreignKey' => false,
        'conditions' => array('FilterCategory.id = CategorysProject.category_id')
))));
$this->Project->find('all', array(
    'fields' => array(DISTINCT (Project.scedule)),
    'conditions'=>array('FilterCategory.slug !='=>'uncategorised')
));
