Answer 1

我相信 cakephp 不支持标准的复合主键：

CakePHP 的多主键问题

尽管该页面确实链接到使用替代的建议解决方法exists（但我必须承认我没有尝试过！）。

Answer 2

没用过cakephp，不过答案应该很简单：

http://book.cakephp.org/2.0/en/models/model-attributes.html

    class Example extends AppModel {
    public $primaryKey = 'example_id'; // example_id is the field name in the database
}
