CakePHP模型关联深层模型包含

我一直在努力解决这个问题,并且已经在我的CakePHP应用程序中与各种其他模型的关联进行了匹配,但仍然无法使结果数组包含相关的ExpenseType。

Everything始于Property,定义为:

  

var $ recursive = 2;

     

var $ actsAs = array('Containable');

模型关联

Property hasMany Bill

Bill belongsTo Property

Bill hasOne ExpenseType

ExpenseType belongsTo Bill


在My PropetiesController中,我调用并分配给$ property:

  

$这 - >属性 - > findById($ ID);

这导致:

Array
(
[Property] => Array
    (
        [id] => 2
        [address] => **
        [bedrooms] => 2
        [bathrooms] => 1.5
        [square_footage] => 973
        [zip_code] => **
        [created] => 2013-08-13 18:30:34
        [modified] => 2013-08-15 19:08:32
    )

[Bill] => Array
    (
        [0] => Array
            (
                [id] => 2
                [expense_type_id] => 1
                [property_id] => 2
                [frequency] => monthly
                [start_date] => 2013-09-16
                [payee] => **
                [amount] => **
                [created] => 2013-08-20 19:57:41
                [modified] => 2013-08-20 20:57:02
            )

        [1] => Array
            (
                [id] => 4
                [expense_type_id] => 4
                [property_id] => 2
                [frequency] => monthly
                [start_date] => 2013-09-15
                [payee] => **
                [amount] => 195
                [created] => 2013-08-20 20:38:11
                [modified] => 2013-08-20 20:38:11
            )

    )
)

对于我的生活,我无法让数组包含Bill下的ExpenseType的详细信息。建议请!

更新:在模型上设置包含方法时,Cake现在报告:

  

模型“Bill”与模型“ExpenseType”

无关

比尔模型

    class Bill extends AppModel {
        /*******************
        * Variables        *
        *******************/
        var $actsAs = array('Containable');

        /*********************
        * Model Associations *
        **********************/
        public $belongsTo = array('Property');
        public $hasOne = array('ExpenseType');
    }

费用类型型号

class ExpenseType extends AppModel {
    /*******************
    * Variables        *
    *******************/
    var $actsAs = array('Containable');

    /*******************
    * Model Associations      *
    *******************/
    public $belongsTo = array('Bill');
}

表格结构

  • 票据
    • ID
    • expense_type_id
    • PROPERTY_ID
    • ...
  • expense_types
    • ID
    • 名称
    • 描述

答案 0 :(得分:3)

我能够通过进行以下更改来实现这一目标:

属性模型

更改:

public $hasMany = array(
        'Bill' => array(
            'className' => 'bills',
            'foreign_key' => 'property_id',
            'dependent' => true
            )
        );

要:

  

public $ hasMany = array('Bill');

比尔模型

  

public $ belongsTo = array('Property','ExpenseType');

费用类型型号

  

public $ hasMany = array('Bill');

似乎Property模型中的无效关联仍然允许查询Bills,但不知何故搞砸了更深层次的关联。不知道为什么它会工作期间。

答案 1 :(得分:1)

一些建议:

1。)在findById

之前递归递归到PropertiesController
$this-Property->recursive = 2;

2。)在Bill和ExpenseType模型上使用可包含的行为

var $actsAs = array('Containable');

...然后在PropertiesController中执行...

$this->Property->contain(array(
    'Bill' => array(
        'ExpenseType'
    )
));

$this->set('property', $this->Property->findById($id));

更新#1:

比尔模型

class Bill extends AppModel {
    /*******************
    * Variables        *
    *******************/
    var $actsAs = array('Containable');


    /*********************
    * Model Associations *
    **********************/
    public $belongsTo = array(
        'Property' => array(
            'className' => 'Property',
            'foreignKey' => 'property_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        ),
        'ExpenseType' => array(
            'className' => 'ExpenseType',
            'foreignKey' => 'expense_type_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        ),
    ); // end belongsTo
} // end Bill model

费用类型模型

class ExpenseType extends AppModel {
    /*******************
    * Variables        *
    *******************/
    var $actsAs = array('Containable');


    /*******************
    * Model Associations      *
    *******************/
    public $hasMany = array(
        'Bill' => array(
            'className' => 'Bill',
            'foreignKey' => 'expense_type_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        ),
    ); // end hasMany

} // end ExpenseType model

然后清除缓存
