CakePHP3：如何保存具有两级HABTM的实体？

此问题中的表格包括：

• 塔里法斯（属于康塔托斯）
• 区域（habtm tarifas）
• tarifas_地区（habtm turnos）
• 塔里法斯图诺斯地区

Tarifas

还有habtm

Dias

，但这种关联没有问题，因为它是一种简单的关联

TarifasTable：

<?php
namespace App\Model\Table;

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

/**
 * Tarifas Model
 *
 * @property \Cake\ORM\Association\BelongsTo $Contratos
 * @property \Cake\ORM\Association\BelongsToMany $Areas
 * @property \Cake\ORM\Association\BelongsToMany $Dias
 *
 * @method \App\Model\Entity\Tarifa get($primaryKey, $options = [])
 * @method \App\Model\Entity\Tarifa newEntity($data = null, array $options = [])
 * @method \App\Model\Entity\Tarifa[] newEntities(array $data, array $options = [])
 * @method \App\Model\Entity\Tarifa|bool save(\Cake\Datasource\EntityInterface $entity, $options = [])
 * @method \App\Model\Entity\Tarifa patchEntity(\Cake\Datasource\EntityInterface $entity, array $data, array $options = [])
 * @method \App\Model\Entity\Tarifa[] patchEntities($entities, array $data, array $options = [])
 * @method \App\Model\Entity\Tarifa findOrCreate($search, callable $callback = null)
 */
class TarifasTable extends Table
{

    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public function initialize(array $config)
    {
        parent::initialize($config);

        $this->table('tarifas');
        $this->displayField('id');
        $this->primaryKey('id');

        $this->belongsTo('Contratos', [
            'foreignKey' => 'contrato_id',
            'joinType' => 'INNER'
        ]);
        $this->belongsToMany('Areas', [
            'foreignKey' => 'tarifa_id',
            'targetForeignKey' => 'area_id',
            'joinTable' => 'tarifas_areas'
        ]);
        $this->belongsToMany('Dias', [
            'foreignKey' => 'tarifa_id',
            'targetForeignKey' => 'dia_id',
            'joinTable' => 'tarifas_dias'
        ]);
    }

    /**
     * Default validation rules.
     *
     * @param \Cake\Validation\Validator $validator Validator instance.
     * @return \Cake\Validation\Validator
     */
    public function validationDefault(Validator $validator)
    {
        $validator
            ->integer('id')
            ->allowEmpty('id', 'create');

        $validator
            ->requirePresence('nome', 'create')
            ->notEmpty('nome');

        $validator
            ->date('dataInicial')
            ->requirePresence('dataInicial', 'create')
            ->notEmpty('dataInicial');

        $validator
            ->date('dataFinal')
            ->requirePresence('dataFinal', 'create')
            ->notEmpty('dataFinal');

        return $validator;
    }

    /**
     * Returns a rules checker object that will be used for validating
     * application integrity.
     *
     * @param \Cake\ORM\RulesChecker $rules The rules object to be modified.
     * @return \Cake\ORM\RulesChecker
     */
    public function buildRules(RulesChecker $rules)
    {
        $rules->add($rules->existsIn(['contrato_id'], 'Contratos'));

        return $rules;
    }

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

因此，在

TarifasTable

中，我编写了这个函数来保存所有

tarifas

（但我仍在调试）：

我有这样的回报：

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

---

那么，我如何告诉CakePHP这些表是如何相互关联的呢？有没有一种方法可以一次保存所有数据？

您需要定义

Tarifas

和

tarifasreas

之间的

关系。在表上定义
belongToMany
关系时，它只关联显式声明的表，而不关联直通表

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


只要
TarifasAreas
的
TarifasAreas
中的外键是
tarifa\u id
就可以了
 是的，很管用！但我不得不更改表名，因为CakePHP3似乎有一个错误，ORM“无法描述TarifasAreas表：它有0列”。这很奇怪！这和命名惯例有什么关系吗通常联接表名称按字母顺序排列
AreasTarifas
