如何为嵌套关系构建适当的CakePHP查询

Question

我是CakePHP的新手，我正在尝试为结果构建复杂的查询。它杀了我。也许some1可以帮助我。 我使用蛋糕2.7

我有两个表有3个关系（多对多）。 Neighbourhood和Polygon。 案例看起来像Neighbourhood有很多Neighbourhoods，它也属于许多Neighbourhoods。此外，Neighbourhood有许多Polygons和Polygon属于mnay Neighbourhoods。

Neighbourhood表包含2个字段name和zip。我从用户那里得到的是zip code。

现在我想要的是： 我想从Polygons及其Neighbourhood获取所有Neighbours。 Neighbourhood.zip = defined by user。

我该怎么做？我应该编写自定义查询或将proccess分成更小的步骤吗？我整天都在和这个人打架。

以下是模型关系的外观：

class Neighbourhood extends AppModel
{
    var $hasAndBelongsToMany = array(
        'Neighbourhoods' => array(
            'className' => 'Neighbourhood',
            'joinTable' => 'neighbourhoods_neighbours',
            'foreignKey' => 'neighbourhood_id',
            'associationForeignKey' => 'neighbour_id',
            'unique' => false
        ),
        'Polygon' => array(
            'className' => 'Polygon',
            'joinTable' => 'neighbourhoods_polygons',
            'foreignKey' => 'neighbourhood_id',
            'associationForeignKey' => 'polygon_id',
            'unique' => false
        ),
    );
}


class Polygon extends AppModel
{
    var $hasAndBelongsToMany = array(
        'Neighbours' => array(
            'className' => 'Neighbourhood',
            'joinTable' => 'neighbourhoods_polygons',
            'foreignKey' => 'polygon_id',
            'associationForeignKey' => 'neighbourhood_id',
            'unique' => false,
        )
    );
}
