CakePHP 3.6.11：更新表中的值

Question

我有这张桌子：

  

客户[id，姓名，姓氏，电话，文字，余额，已创建]

     

service_types [id，标题，价格，长度，is_subscription，已创建]

     

customer_service_types [id，customer_id，service_type_id，价格，已创建]

当我为客户添加新的customerServiceType时，我想使用给定的balance的{​​{1}}值来更新客户的price。

这就是我尝试过的：

customerServiceType：

CustomerServiceTypes/add.ctp

<fieldset> <legend><?= __('Add Customer Service Type') ?></legend> <?php echo $this->Form->control('customer_id', ['options' => $customers]); echo $this->Form->control('service_type_id', ['options' => $serviceTypes]); echo $this->Form->control('price'); ?> </fieldset> <?= $this->Form->button(__('Submit')) ?> <?= $this->Form->end() ?> ：

Model/Entity/CustomerServiceType.php

因此，在class CustomerServiceType extends Entity { //On create a new CustomerServiceType then update the selected customer's balance public function addCustomerServiceType($data = array()){ $this->create; $this->save($data); //update customer balance $customer = $this->Customers->get($data['customerid']); $this->Customer->updateAll( array('Customer.balance' => 'Customer.balance + ' . $data['price']), array('Customer.id' => $data['customerid']) ); return true; } } 中，我像这样更改了CustomerServiceTypesController.php：

add()

但是我得到这个错误：

  

在布尔值上调用成员函数addCustomerServiceType（）

此通知：

  

未定义的属性：CustomerServiceTypesController :: $ CustomerServiceType

由于您希望在保存数据后发生，因此我认为使用Model.afterSave事件：https://book.cakephp.org/3.0/en/orm/table-objects.html#aftersave

在您的控制器中

$this->CustomerServiceTypes->save($customerServiceType)

在表对象CustomerServiceTypesTable.php

namespace App\Model\Table;

use Cake\ORM\Table;
use Cake\Event\Event;
use Cake\ORM\TableRegistry;
use ArrayObject;
use Cake\Datasource\EntityInterface;

class CustomerServiceTypesTable extends Table
{
    public function afterSave(Event $event, EntityInterface $entity, ArrayObject $options)
    {
        // only execute if the entity is new
        // if you want this to happen on edits too, remove this clause

        if ($entity->isNew()) {
            // get instance of the Customers table
            $customers = TableRegistry::getTableLocator()->get('Customers');

            $customer = $customers->get($entity->customerid);
            // do more stuff here
        }
    }
}
