cakePHP 4 实体保存仅在第二次有效

Question

我有 18n 本地化，如果这很重要的话。我已经尝试了一切，但我只是不明白问题是什么。 课程类别控制器.php

public function add()
    {
        $model = 'CoursesCategories';

        if(isset($_GET['lang']) && $_GET['lang'] == 'kz'){
            $this->$model->setLocale('kz');
        }elseif(isset($_GET['lang']) && $_GET['lang'] == 'en'){
            $this->$model->setLocale('en');
        }else{
            $this->$model->setLocale('ru');
        }

        if( $this->request->is('post') ){
            $data = $this->request->getData();

            $entity = $this->$model->newEntity($data);
            if( $entity->getErrors() ){

                $errors = $entity->getErrors();
                foreach( $errors as $index => $err ){
                    $this->Flash->error( $err[array_key_first($err)] );
                }
                return $this->redirect( $this->referer() );
            }
            if( $this->$model->save($entity) ){
                $this->Flash->success(__('Данные успешно сохранены'));
                return $this->redirect( $this->referer() );
            } else{
                $this->Flash->error(__('Ошибка сохранения данных'));
            }
        }
    }

但是如果我在“if”之前添加另一个保存，那么第一个不起作用，但第二个已经起作用：

$this->$model->save($entity)
if( $this->$model->save($entity) ){

我错过了什么？

I just don’t understand what the reason is, I’ve probably already looked at all the files and tried everything I know

我能够以某种方式弄清楚。最后，为了让一切正常工作，你需要这样做：

class CoursesCategory extends Entity
{
    use TranslateTrait;
    // use TranslateStrategyTrait;
    /**
     * Fields that can be mass assigned using newEntity() or patchEntity().
     *
     * Note that when '*' is set to true, this allows all unspecified fields to
     * be mass assigned. For security purposes, it is advised to set '*' to false
     * (or remove it), and explicitly make individual fields accessible as needed.
     *
     * @var array
     */
    protected $_accessible = [
        'title' => true,
        '_translations' => true
    ];
}

控制器添加：

public function add(){
    $model = 'CoursesCategories';

    if(isset($_GET['lang']) && $_GET['lang'] == 'kz'){
        $this->CoursesCategories->setLocale('kz');
    }elseif(isset($_GET['lang']) && $_GET['lang'] == 'en'){
        $this->CoursesCategories->setLocale('en');
    }else{
        $this->CoursesCategories->setLocale('ru');
    }

    if( $this->request->is('post') ){
        $data = $this->request->getData();
        // $this->CoursesCategories->setLocale('ru');
        // $courseCategory = $this->CoursesCategories->newEntity($data);
        $courseCategory = $this->CoursesCategories->newEmptyEntity();
        // debug($this->CoursesCategories->getLocale()); die;
        $courseCategory->translation($this->CoursesCategories->getLocale())->set($data);
        // $entity->_translations['ru'] = $data;
        // $entity->locale='ru';
        // debug($entity); die;
        if( $this->$model->save($courseCategory) ){
            $this->Flash->success(__('Данные успешно сохранены'));
            return $this->redirect( $this->referer() );
        } else{
            $this->Flash->error(__('Ошибка сохранения данных'));
        }
    }
}

控制器编辑：

public function edit($item_id = null){
    if(isset($_GET['lang']) && $_GET['lang'] == 'kz'){
        $this->CoursesCategories->setLocale('kz');
    }elseif(isset($_GET['lang']) && $_GET['lang'] == 'en'){
        $this->CoursesCategories->setLocale('en');
    }else{
        $this->CoursesCategories->setLocale('ru');
    }
    $CoursesCategories = $this->CoursesCategories->get($item_id);
    if ($this->request->is(['post', 'put'])) {
        $new_data = $this->request->getData();
        // $old_data = clone $data;

        $CoursesCategories->translation($this->CoursesCategories->getLocale())->set($new_data);
        if( $CoursesCategories->getErrors() ){
            $errors = $CoursesCategories->getErrors();
            foreach( $errors as $index => $err ){
                $this->Flash->error( $err[array_key_first($err)] );
            }
            return $this->redirect( $this->referer() );
        }

        $new_data = $CoursesCategories->toArray();
        $this->CoursesCategories->patchEntity($CoursesCategories, $new_data);

        if ($this->CoursesCategories->save($CoursesCategories)) {
            $this->Flash->success(__('Изменения сохранены'));
            return $this->redirect( $this->referer() );
        }
        $this->Flash->error(__('Ошибка сохранения'));
    }
    $this->set( compact('CoursesCategories') );
}
