【问题描述】：

我有一个实体（预订），我手动为其设置了一些值，而其他值是使用 patchEntity 设置的。 但是在保存时，我收到一条错误消息，指出缺少两个必填字段。

这是实体调试的样子：

object(App\Model\Entity\Booking) 

    'provider_pk' => (int) 2,
    'date' => object(Cake\I18n\Time) 

        'time' => '2016-03-31T00:00:00+00:00',
        'timezone' => 'UTC',
        'fixedNowTime' => false

    ,
    'start' => object(Cake\I18n\Time) 

        'time' => '2016-03-31T08:00:00+00:00',
        'timezone' => 'UTC',
        'fixedNowTime' => false

    ,
    'modules_count' => (int) 1,
    'requester_pk' => (int) 1,
    'remarks' => '',
    'status_id' => (int) 1,
    'end' => object(Cake\I18n\Time) 

        'time' => '2016-03-31T09:00:00+00:00',
        'timezone' => 'UTC',
        'fixedNowTime' => false

    ,
    '[new]' => true,
    '[accessible]' => [
        '*' => true
    ],
    '[dirty]' => [
        'provider_pk' => true,
        'date' => true,
        'start' => true,
        'modules_count' => true,
        'requester_pk' => true,
        'remarks' => true,
        'status_id' => true,
        'end' => true
    ],
    '[original]' => [],
    '[virtual]' => [],
    '[errors]' => [
        'date' => [
            '_required' => 'This field is required'
        ],
        'start' => [
            '_required' => 'This field is required'
        ]
    ],
    '[invalid]' => [],
    '[repository]' => 'Bookings'

如您所见，“日期”和“开始”字段有值，但在错误部分中，显示它们缺失。

这就是我创建新实体的方式（$date 和 $start 具有相应的值）：

    $booking = $this->Bookings->newEntity( [ 'provider_pk' => $provider_pk, 'date' => $date, 'start' => $start ] );

然后我使用patchEntity，在保存之前，我手动设置了另一个字段，然后尝试这样保存：

   $booking = $this->Bookings->patchEntity($booking, $this->request->data);

    $booking->end = $end->modify( '+' . $booking->modules_count .  ' hours' );
    if ($this->Bookings->save($booking)) 
    
        $this->Flash->success(__('The booking has been saved.'));
        return $this->redirect( ['action' => 'show' ] );
     else ...

然后 $booking->errors() 给出这个：

[

    'date' => [
        '_required' => 'This field is required'
    ],
    'start' => [
        '_required' => 'This field is required'
    ]
]

如您所见，即使最初有值，也声称需要日期和开始字段。

我做错了什么？

这是表格模型：

<?php
namespace App\Model\Table;

use App\Model\Entity\Booking;
use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\ORM\Table;
use Cake\Validation\Validator;

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

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

        $this->belongsTo('Statuses', [
            'foreignKey' => 'status_id',
            'joinType' => 'INNER'
        ]);

        // ---------------------------------------------------------------------
        // customize for every project

        $this->hasMany( 'Aircrafts' );
        $this->belongsTo( 'Pilots', [ 'foreignKey' => 'requester_pk', 'joinType' => 'LEFT' ] );

    

    /**
     * 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
            ->date('date')
            ->requirePresence('date', 'create')
            ->notEmpty('date');

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

        $validator

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

        $validator
            ->integer('provider_pk')
            ->allowEmpty('provider_pk');

        $validator
            ->integer('assistant_pk')
            ->allowEmpty('assistant_pk');

        $validator
            ->allowEmpty('remarks');

        return $validator;
    

    /**
     * Returns a rules checker object that will be used for validating
     * application integrity.
     *

    public function buildRules(RulesChecker $rules)
    
        $rules->add($rules->existsIn(['status_id'], 'Statuses'));
        return $rules;
    

这是控制器方法：

/** form for booking confirmation
*
* @param string|null $id cell id.
* @return \Cake\Network\Response|null Redirects to bookings / show .
**/

public function confirmBooking()

    if( isset( $this->request->query['id']) )
    
        $id = $this->request->query['id'];

        $token = strpos( $id, '-' );

        $day = substr( $id, $token + 1 , 2 );
        $month = substr( $id, $token + 3 , 2 );
        $year = substr( $id, $token + 5 , 4 );
        $hour = substr( $id, $token + 9 , 2 );
        $minutes = substr( $id, $token + 11, 2 );

        $date = Time::createFromTimestamp( mktime( 0, 0, 0, $month, $day, $year ) );
        $start = Time::createFromTimestamp( mktime( $hour, $minutes, 0, $month, $day, $year ) );
        $end = Time::createFromTimestamp( mktime( $hour + 1, $minutes, 0, $month, $day, $year ) );
        $provider_pk = substr( $id, 1, $token - 1 );
    

    $aircrafts =  $this->Bookings->Aircrafts->find( 'all', [ 'order' => 'registration' ] );
    $this->set( 'aircrafts', $aircrafts );

    // ---------------------------------------------------------------------
    // depending on add or update

    if( isset( $this->request->query['booking_id'] ) )
        $booking = $this->Bookings->get($this->request->query['booking_id'], [ 'contain' => [ 'Pilots' ] ] );
    else
    
        $booking = $this->Bookings->newEntity( [ 'provider_pk' => $provider_pk, 'date' => $date, 'start' => $start, 'end' => $end, 'modules_count' => 1 ] );
    

    if ($this->request->is('post') || ( $this->request->is('put') &&  isset( $this->request->query['booking_id'] ) ) ) 

        debug( $this->request->data );

        $booking = $this->Bookings->patchEntity($booking, $this->request->data);

        $booking->end = $end->hour( $this->request->data[ 'end_value' ][ 'hour' ] );

        $booking->modules_count = $booking->end->diff( $booking->start )->format('%h');


        if ($this->Bookings->save($booking)) 
        
            $this->Flash->success(__('The booking has been saved.'));
            return $this->redirect( ['action' => 'show' ] );
         else 
        
            $this->Flash->error(__('The booking could not be saved. Please, try again.')  );
            return $this->redirect(['action' => 'show']);
        
    

    $statuses = $this->Bookings->Statuses->find('list', ['limit' => 200]);
    $assistants = $this->Bookings->Pilots->find( 'list' , [ 'conditions' => [ 'is_instructor =' => true ], 'fields' => [ 'id', 'firstname' ] ] );

    $this->set('_serialize', ['booking']);

    $this->set( 'requesters', $requesters );
        

【问题讨论】：

您能否向我们展示所有表格代码以及您正在执行此操作的控制器操作？你只是给了我们一小块拼图。

【参考方案1】：

我想我找到了问题所在。 问题是验证器中的“requirePresence”规则。 由于该字段不是通过表单获取的（由控制器设置为默认值），因此它不存在于传递的数组中。 我说的对吗？

问候。 法昆多。
