Question

我正在尝试绑定公司hasMany CompanyReview。以下是控制器中的代码：

public function review() {
    $this->uses = array('Search', 'Company', 'CompanyReview');
    $this->Company->bindModel(array(
        'hasMany' => array(
            'CompanyReview' => array(
            'className' => 'CompanyReview',
            'foreignKey' => 'company_id'
            )
        )
    ));
    $this->CompanyReview->bindModel(
        array(
           'belongsTo'=>array(
                'Company'=>array(
                    'className'=>'Company',
                    'foreignKey'=>'company_id'
                 )
            )
        )
    );

    if (!empty($this->data)) {
        switch ($this->data['Search']['search_type']) {
            case 'all':
                $this->request->data['ReviewResults'] = $this->allReviews($this->data['Search']['search_query']);
                break;
            case 'company':
                $this->request->data = $this->Company->find('all', array(
                   'conditions' => array(
                      'OR' => array(
                          'MATCH(Company.name) against ("' . $this->data['Search']['search_query'] . '" in boolean mode)',
                          'MATCH(CompanyReview.job_title) against ("' . $this->data['Search']['search_query'] . '" in boolean mode)'
                           )

                        )
                    ));
                break;
            case 'interview':
                $this->request->data['ReviewResults'] = $this->interviewReviews($this->data['Search']['search_query']);
                break;
            case 'salary':
                $this->request->data['ReviewResults'] = $this->salaryReviews($this->data['Search']['search_query']);
                break;
            }
        }
    }

但我一直得到的错误是：数据库错误

Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'CompanyReview.job_title' in 'where clause'

SQL查询：

SELECT Company.id, Company.name, Company.industry_id, Company.website, Company.created FROM terbang2.companies AS Company WHERE ((MATCH(Company.name) against ("air" in boolean mode)) OR (MATCH(CompanyReview.job_title) against ("air" in boolean mode)))

注意：如果您要自定义此错误消息，请创建 app / View / Errors / pdo_error.ctp

如果您注意到，则sql不包含company_reviews表。怎么回事？请帮忙！。感谢

哦，顺便说一句，在company_reviews表中有一个名为job_title的表行。

Answer 1

您需要使用[Joins]。

从关联自动构建的“正常”查询实际上为每个模型分别进行查询，因此您无法引用其表中不存在的字段，并且会导致错误（如您所说的那样）如果试过的话。

Answer 2

如果你想让蛋糕自动化使用$this->CompanyReview->find();，因为只有在$belongsTo和$hasOne的情况下，蛋糕才会加入。在$hasMany和HABTM中有单独的查询。如果你想/需要在公司找到，你需要做@Dave提到的连接。

请注意。您不需要双向绑定。如果您确实在公司上找到，则仅绑定到公司模型。

Cakephp bindModel不能正常工作
