Cakephp 3:如何忽略特定查询的beforefind?

标签: entity exists cakephp-3.0

我正在处理多语言帖子。我在PostsTable中添加了beforefind(),因此我可以列出当前语言的帖子

public function beforeFind(Event $event, Query $query) {

    $query->where(['Posts.locale' => I18n::locale()]);
}

为了允许用户使用不同语言复制帖子,我编写了以下功能:

public function duplicate(){
    $this->autoRender = false;
    $post_id= $this->request->data['post_id'];

    $post = $this->Posts
            ->findById($post_id)
            ->select(['website_id', 'category_id', 'locale', 'title', 'slug', 'body', 'image', 'thumb', 'meta_title', 'meta_description', 'other_meta_tags', 'status'])
            ->first()
            ->toArray();

    foreach($this->request->data['site'] as $site) {
        if($site['name'] == false) {
            continue;
        }
        $data = array_merge($post, [
            'website_id' => $site['website_id'],
            'locale' => $site['locale'],
            'status' => 'Draft',
            'duplicate' => true
        ]);


        $pageData = $this->Posts->newEntity($data);

        if($this->Posts->save($pageData)) {
            $this->Flash->success(__('Post have been created.'));;
        } else{
            $this->Flash->error(__('Post is not created.'));
        }

    }

    return $this->redirect(['action' => 'edit', $post_id]);
}

检查帖子是否已经重复。我正在办理登机手续'编辑' functino:

    $languages = TableRegistry::get('Websites')->find('languages');

    foreach($languages as $language)
    {
        $exists[] = $this->Posts
                    ->findByTitleAndWebsiteId($post['title'], $language['website_id'])
                    ->select(['locale', 'title', 'website_id'])
                    ->first();
    }
    $this->set('exists',$exists); 

但是,因为beforefind()将查询附加到上面的查询。我没有得到任何结果。有没有什么方法可以忽略beforefind()只用于cerrtain查询。我尝试使用如下实体:

public function beforeFind(Event $event, Query $query) {

    if(isset($entity->duplicate)) {
        return true;
    }
    $query->where(['Posts.locale' => I18n::locale()]);
}

但没有运气。谁能指导我?谢谢阅读。

有多种方法可以解决这个问题,一种方法是利用Query::applyOptions()设置一个可以在回调中检查的选项

$query->applyOptions(['injectLocale' => false])
public function beforeFind(Event $event, Query $query, ArrayObject $options)
{
    if(!isset($options['injectLocale']) || $options['injectLocale'] !== false) {
        $query->where(['Posts.locale' => I18n::locale()]);
    }
}

警告$options参数目前作为数组传递,而它应该是ArrayObject#5621)的实例

使用以下内容可以忽略

Callback methods

$this->Model->find('all', array(
     'conditions' => array(...),
     'order' => array(...),
     'callbacks' => false
));
