CakePHP 3：如何保存具有两级HABTM的实体？

这个问题的演变表是：

  • tarifas（属于contratos）
  • 地区（habtm tarifas）
  • tarifas_areas（habtm turnos）
  • tarifas_areas_turnos

Tarifas也是Dias，但这种关联没有问题，因为这是一个简单的关联。

TarifasTable：

use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;

这是我要保存的数据（它是json的一部分）：

"tarifas": [
        {
            "nome": "T1",
            "dataInicial": "2017-01-10",
            "dataFinal": "2018-01-10",
            "dias": [
                {
                    "id": 1,
                    "_joinData": [] 
                },
                {
                    "id": 2,
                    "_joinData": [] 
                },
                {
                    "id": 3,
                    "_joinData": [] 
                },
                {
                    "id": 4,
                    "_joinData": [] 
                },
                {
                    "id": 5,
                    "_joinData": [] 
                }
            ],
            "TarifasAreas": [
                {
                    "area_id": 3,
                    "TarifasAreasTurnos": [
                        {
                            "turno_id": 4,
                            "valor": 20
                        }
                    ]
                }
            ]
        }
    ]

所以，在TarifasTable我编写了这个函数来保存所有tarifas（但我还在调试）：

public function salvaTarifasContrato($idContrato, $dadosTarifas){
    $tarifas = $this->newEntities(
        $dadosTarifas,
        ['associated' => ['TarifasAreas', 'TarifasAreas.TarifasAreasTurnos']]
    );
    debug($tarifas); die();
}

我有这个回报：

{
  "message": "Cannot marshal data for \"TarifasAreas\" association. It is not associated with \"Tarifas\".",
  "url": "/project/api/contratos",
  "code": 500
}

那么，我怎么能告诉CakePHP这些表如何相互关联？有没有办法一次性保存这些数据？

1 个答案:

答案 0 :(得分：1)

您需要在hasMany和Tarifas之间定义TarifasAreas关系。在表上定义belongsToMany关系时，它只涉及明确声明的表而不是直通表。

// TarifasTable.php
$this->hasMany('TarifasAreas');

https://book.cakephp.org/3.0/en/orm/associations.html#hasmany-associations

只要TarifasAreas Tarifas中的外键为tarifa_id，这就行了！
