我有表项目，截图，sub_screenshot和用户
我想实现这种图表。它就像获得第四级。

此致

Answer 1

为了让您了解我建议您使用afterFind()回调

http://book.cakephp.org/view/1050/afterFind

在find之后，将User设置为使用User模型进行另一次查找。

我不知道是否存在任何配置来修改$recursive而没有修改核心。

修改

您可以在AppModel中创建一个通用的afterFind，以检查是否有$ recursive = 4并复制关系的核心功能并生成它们。

Answer 2

使用可包含的行为。我最近也有一些问题。将递归设置为4会更有效，因为您只需要包含所需的模型。

按照以下说明设置模型的行为。 http://book.cakephp.org/view/1323/Containable

然后，您应该能够执行查找并获得所需的结构。

$this->Project->find(
    'all',
    array(
        'conditions' => array(
            //put your conditions in here
        ),
        'contain' => array(
             'User',
             'Screenshot',
             'Screenshot.SubScreenshot'
             'Scrrenshot.SubScreenshot.User'
    )
);

有几种方法可以使用模型语法。您可以将数组添加到包含的模型中以添加条件和/或进一步深度。
