用这种关系保存正确的数据数组

Question

class Post extends AppModel {
    var $name = 'Post';
    var $hasMany = array(
        'CategoryPost' => array(
            'className' => 'CategoryPost'
        )
    );
    var $belongsTo = array(
        'Page' => array(
            'className' => 'Page'
        )
    );

class Category extends AppModel {
    var $name = 'Category';
    var $hasMany = array(
        'CategoryPost' => array(
            'className' => 'CategoryPost'
        )
    );

class CategoryPost extends AppModel {
    var $name = 'CategoryPost';
    var $validate = array(
        'category_id' => array(
            'rule'     => array('multiple', array('in' => array(1, 2, 3, 4))),
            'required' => FALSE,
            'message'  => 'Please select one, two or three options'
        )
    );
    var $belongsTo = array(
        'Post' => array(
            'className' => 'Post'
        ),
        'Category' => array(
            'className' => 'Category'
        )
    );

这是使用 saveAll 保存该数组所需的正确格式吗？这不会保存 CategoryPost 模型。如果不是，数组的格式应该是什么？

Array
(
    [Post] => Array
        (
            [title] => query
            [body] => 

query

            [page_id] => 122
            [modified] => 2010-12-30 23:33:47
            [created] => 2010-12-30 23:33:47
            [uri] => query-9
        )

    [CategoryPost] => Array
        (
            [0] => Array
                (
                    [category_id] => 1
                )

            [1] => Array
                (
                    [category_id] => 2
                )

        )

    [Page] => Array
        (
            [meta_keywords] => query
            [meta_description] => query
            [title] => query
            [layout] => index
        )

)

Answer 1

好吧，一切看起来都很好，CategoryPost 数据应该被保存。

也许可以注释掉 CategoryPost 模型中的验证，然后尝试。
