CakePHP:未定义索引：

我真的很困惑。我一直得到一个未定义的索引

        [Makemodel] => Array
            (
                [0] => Array
                    (
                        [id] => 2
                        [ModelName] => Focus
                        [make_id] => 2
                        [Road] => Array
                            (
                                [0] => Array
                                    (
                                        [id] => 1
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 1
                                        [name] => Dirt
                                    )

                                [1] => Array
                                    (
                                        [id] => 2
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 2
                                        [name] => Snow
                                    )

                            )

                    )

            )

    )

控制器：

function makemodel($id = null) {
    $this->Make->id = $id;

    $makes = $this->Make->find('all', array(
        'conditions' => array('id' => $id),
        'contain' => array('Makemodel' => array('Road'))
        )
    );

    $this->set(compact('makes'));
}

        [Makemodel] => Array
            (
                [0] => Array
                    (
                        [id] => 2
                        [ModelName] => Focus
                        [make_id] => 2
                        [Road] => Array
                            (
                                [0] => Array
                                    (
                                        [id] => 1
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 1
                                        [name] => Dirt
                                    )

                                [1] => Array
                                    (
                                        [id] => 2
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 2
                                        [name] => Snow
                                    )

                            )

                    )

            )

    )

                                        [name] => Dirt
                                    )

                                [1] => Array
                                    (
                                        [id] => 2
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 2
                                        [name] => Snow
                                    )

                            )

                    )

            )

    )

我在回响。来自数组的正确$Make['Make']['MakeName']

        [Makemodel] => Array
            (
                [0] => Array
                    (
                        [id] => 2
                        [ModelName] => Focus
                        [make_id] => 2
                        [Road] => Array
                            (
                                [0] => Array
                                    (
                                        [id] => 1
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 1
                                        [name] => Dirt
                                    )

                                [1] => Array
                                    (
                                        [id] => 2
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 2
                                        [name] => Snow
                                    )

                            )

                    )

            )

    )

我还尝试了$Make['Make'][0]['MakeName']

        [Makemodel] => Array
            (
                [0] => Array
                    (
                        [id] => 2
                        [ModelName] => Focus
                        [make_id] => 2
                        [Road] => Array
                            (
                                [0] => Array
                                    (
                                        [id] => 1
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 1
                                        [name] => Dirt
                                    )

                                [1] => Array
                                    (
                                        [id] => 2
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 2
                                        [name] => Snow
                                    )

                            )

                    )

            )

    )

它声明其在['Make'有问题]

        [Makemodel] => Array
            (
                [0] => Array
                    (
                        [id] => 2
                        [ModelName] => Focus
                        [make_id] => 2
                        [Road] => Array
                            (
                                [0] => Array
                                    (
                                        [id] => 1
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 1
                                        [name] => Dirt
                                    )

                                [1] => Array
                                    (
                                        [id] => 2
                                        [makemodel_id] => 2
                                        [RoadTypeID] => 2
                                        [name] => Snow
                                    )

                            )
