cakephp3 中的深度关联不保存数据

Question

我与其他 6 张桌子有这样的关联

company ==> hasMany Cohorts

和

Cohorts ==> contains hasMany

例如：

CohortTimeConfig

。

现在我正在从群组表中检索默认值，这样就可以了。

$cohorts = $this->Companies->Cohorts
        ->find('all', [
            'conditions' => [
                'company_id IS NULL and status_id = 1'
            ],
            'contain' => [
                'CohortConfigs',
                'CohortPpmCategories',
                'CohortRanges',
                'CohortRoadClassConfig',
                'CohortTimeConfig',
                'CohortWeatherConfig'
            ],
            'order' => ['id' => 'ASC']
        ])
        ->toArray(); 

现在我正在做的就是像这样改变$cohorts

$company_id = $company->id;
array_walk($cohorts, function (&$cohort, $index) use ($company_id) {
    unset($cohort['id']);
    $cohort['company_id'] = $company_id;

    //cohort_time_config
    if(!empty($cohort['cohort_time_config'])){
        array_walk($cohort['cohort_time_config'], function (&$cohort_time_config, $key) {
            unset($cohort_time_config['id']);
            unset($cohort_time_config['cohort_id']);
        });
    }
});

最后我试图像这样保存所有具有关联的值

$allCohorts = $this->Companies->Cohorts->newEntity();
$allCohorts = $this->Companies->Cohorts->patchEntity($allCohorts, $cohorts);

debug(
    $this->Companies->Cohorts->save($allCohorts,[
        'atomic'=>true,
        'validate' => true,
        'associated' => [
            'CohortConfigs',
            'CohortPpmCategories',
            'CohortRanges',
            'CohortRoadClassConfig',
            'CohortTimeConfig',
            'CohortWeatherConfig'
        ]
    ])
);

我想提一下，我的

//debug($allCohorts->errors());

没有给出任何错误。这意味着所有规则检查都正常。但数据没有被保存。

有人可以帮助我吗？我该如何调试它为什么不保存数据？

Answer 1

您的查询看起来像检索许多数据并想要保存许多数据，但您使用就像保存一个数据
您的实体

$allCohorts = $this->Companies->Cohorts->newEntity();
$allCohorts = $this->Companies->Cohorts->patchEntity($allCohorts, $cohorts);

应该是这样的

$allCohorts = $this->Companies->Cohorts->newEntities();
$allCohorts = $this->Companies->Cohorts->patchEntities($allCohorts, $cohorts);

或者您也可以使用

$allCohorts = $this->Companies->Cohorts->newEntities($allCohorts);
$this->Companies->Cohorts->saveMany($allCohorts);
