Question

我定义了以下模型关系：

class Publication extends AppModel {

    var $name = 'Publication';

    var $hasAndBelongsToMany = array(
        'Author'=>array(
            'className'=>'Author'
        )
    );     
}

class Author extends AppModel {

    var $name = 'Author';

    var $hasAndBelongsToMany = array(
        'Publication'=>array(
            'className'=>'Publication'
        )
    );

    var $belongsTo = array(
        'College' => array (
            'className' => 'College'
        )
    );      
}

class College extends AppModel {

    var $name = 'College';

var $hasMany = array(
        'Department'=>array(
            'className'=>'Department'
        )
    );      
}

class Department extends AppModel {

    var $name = 'Department';

var $belongsTo = array(
        'College'=>array(
            'className'=>'College'
        )
    );      
}

正确设置数据库表（HABTM的连接表等）。我试图找到一个数据库查询来统治它们。我想创建一个查询，找到所有与相关作者，学院，部门等相关的出版物。从表单中获取数据后，我试图运行这样的查询：

 $conditions = array(
            "Author.id" => $this->data['authors'],
            "Publication.year" => $this->data['year']                                
            );
$publications = $this->Publication->find('all', array('conditions' => $conditions));

这会抛出SQL错误，说Author.id不是有效字段。现在，这是因为在搜索Author.id时尚未完成与'authors'db表的连接。但是，如果我这样做：

$pubs = $this->Publication->find('all', array('conditions' => $conditions));

然后我得到一个包含所有相关作者的所有出版物的数组（但由于某种原因，不是相关的学院）。

我的问题是：在搜索Author.id之前，我需要做什么才能使表加入？我试图使用bindModel，包含子查询，但由于某种原因（可能是ID10T错误）无法使用它们。

感谢您的任何建议！

编辑：以下调用的结果：

$this->Publication->recursive = 2;
$pubs = $this->Publication->find('all');

如下：

希望这有点可读......

Answer 1

你的第二个发现是正确的

即。 $pubs = $this->Publication->find('all', array('conditions' => $conditions));

就在上面尝试使用递归2（代码下面）来获得相关的College。

$this->Publication->recursive = 2;

cakephp - 一个find（）查询来统治它们
