Question

我无法保存（更新）与主模型具有hasMany关系的模型AvailabilityForTutors的关联表单数据。我使用复选框更新了＆＃39; AvailabilityForTutors的一些选项。 NOT_AVAILABLE＆＃39;领域。我添加了id，但没有区别。更新的＆＃39; AvailabilityForTutors。 NOT_AVAILABLE＆＃39;字段未在数据库中更新。我没有收到错误，导师的主要模型数据确实存在。

我检查过这个简单任务的文档和过去的帖子，我无法得到它。我做错了。

//controller
  $tutor = $this->Tutors->get($id, [
        'contain' => ['AvailabilityForTutors']
    ]);
  if ($this->request->is(['patch', 'post', 'put'])) {


         debug($this->request->data);
            $tutor = $this->Tutors->patchEntity($tutor, $this->request->data,['associated' => ['AvailabilityForTutors'],'validate' => false ] );

            if ($this->Tutors->save($tutor)) {
                $this->Flash->success(__('The tutor has been saved.'));
               return $this->redirect(['action' => 'edittest2',$id]);
            } else {
                $this->Flash->error(__('The tutor could not be saved. Please, try again.'));
            }


        }

//view

  <?php

            echo $this->Form->hidden('id', ['value'=>$id]);
            echo $this->Form->input('first_name',['label' => 'Tutor FirstName']);
            echo $this->Form->input('last_name',['label' => 'Tutor LastName']);




            foreach ($tutor->availability_for_tutors as $key => $item) {

               echo $this->Form->hidden('AvailabilityForTutors.'.$key.'.id', ['value'=>$item->id]);

               echo $this->Form->input('AvailabilityForTutors.'.$key.'.not_available', ['label'=>$item->weekday,
                'checked'=> $item->not_available,'type'=>'checkbox']);



           }


model tutor//

 $this->hasMany('AvailabilityForTutors', [
            'foreignKey' => 'tutor_id'
        ]);


posted data which is correct


'id' => '12',
    'first_name' => 'fred',
    'last_name' => 'Tow',
    'AvailabilityForTutors' => [
        (int) 0 => [

UPDATE-调试修补数据对象（App \ Model \ Entity \ Tutor）{

'id' => (int) 12,
'tutor_inactive' => false,
'first_name' => 'fred2',
'last_name' => 'Tow2',

'availability_for_tutors' => [
    (int) 0 => object(App\Model\Entity\AvailabilityForTutor) {

'AvailabilityForTutors' => [
    (int) 0 => [
        'id' => '36',
        'not_available' => '1'

//请参阅not_available与修补数据输出

不同

Answer 1

也许其中一种方法可以帮助你我猜你需要更换 http://api.cakephp.org/3.2/class-Cake.ORM.Association.HasMany.html

我尝试的方式和你一样，但失败了，但是链接（）对我有用（对于HABTM）

Answer 2

尝试在$tutor->dirty('availability_for_tutors', true);功能之后在Controller中插入patchEntity。它会将您的关联标记为“脏”（已修改），以便在调用$this->Tutors->save方法时将其保存。
