CakePHP和tinyint作为布尔值

如何强制CakePHP 2.x检索tinyint数据库列不是布尔值，而是tinyint？

How can I force CakePHP 2.x to retrieve tinyint database column not as boolean but as tinyint?

MySQL：

Column        |    type
-------------------------------
...           |    ...
category_id   |    tinyint(1)
...           |    ...

CakePHP：

$this->request->data = $this->Question->read();
var_dump($this->request->data['Question']['category']);

该值始终为0（如果我将提取的问题归类为类别ID 0）或1 （如果问题有任何其他类别ID）。

The value is always 0 (if the question I'm fetching as the category id 0) or 1 (if the question has any other category id).
