Question

我正在使用 Cakephp 3.2.10

我可以使用hasOne关联和hasMany关联加载关联数据。但是，我在与hasMany关联的表中有一个hasOne，这会产生错误。

我有以下表格

公司
company_revenues
货币
状态
国家。

CompaniesTable类与州，国家有关联，并且有效。 CompaniesTable与CompanyRevenuesTable有很多关联，它有效。 CompanyRevenues表与货币有一个hasOne关联，这会产生错误。

我的相关代码：

CompaniesTable.php

USER_ID

CompanyRevenuesTable.php

<?php

namespace Admin\Model\Table;

use Cake\ORM\Table;
use Cake\ORM\Query;

use Cake\ORM\RulesChecker;

class CompaniesTable extends Table
{
    public function initialize(array $config)
    {
        $this->primaryKey('company_id');

        $this->addAssociations(
        [
            'hasOne' =>
            [
                'Countries' =>
                [ 'className' => 'Countries','foreignKey' => 'id','bindingKey' => 'company_country_id' ]
                ,'States' =>
                [ 'className' => 'States','foreignKey' => 'id','bindingKey' => 'company_state_id' ]
                ,'Sectors' =>
                [ 'className' => 'Sectors','foreignKey' => 'id','bindingKey' => 'company_sector_id' ]

            ]
            ,'hasMany' =>
            [
                'CompanyRevenues' =>
                [ 'className' => 'CompanyRevenues','foreignKey' => 'revenue_company_id','bindingKey' => 'company_id' ]
            ]
        ]);
    }

    public function buildRules(RulesChecker $rules)
    {
        $rules->add( $rules->isUnique(['company_name']) );
        return $rules;
    }


    public function compsTotalCount( Query $query )
    {
        $result = $query->select(['companiesCount' => $query->func()->count('*')])->first();
        return $result;
    }   

    public function findPopular( Query $query )
    {
        $result = $query->where(['times_viewed >' => 10]);
        // debug($result);
        return $result;
    }   
}
?>

My CompaniesController.php

个人资料操作

<?php

namespace Admin\Model\Table;

use Cake\ORM\Table;
use Cake\ORM\Query;

use Cake\ORM\RulesChecker;

class CompanyRevenuesTable extends Table
{
    public function initialize(array $config)
    {
        $this->table('company_revenues');

        $this->addAssociations(
        [
            'hasOne' =>
            [
                'Currencies' =>
                [ 'className' => 'Currencies','foreignKey' => 'id','bindingKey' => 'revenue_currency_id' ]

            ]
        ]);
    }
}
?>

$$ companyRevenues上的调试

给出错误

public function profile( $id = null )
{
    $company = $this->Companies->find()
                ->where(['company_id' => $id])
                ->contain(['CompanyRevenues'])->first();

    if( ! $this->request->is('ajax') )
    {
        $companyRevenuesTable = TableRegistry::get('CompanyRevenues');
        $companyRevenues = $companyRevenuesTable->find()
                                        ->where(['revenue_company_id' => $company->company_id])
                                        ->contain(['Currencies']);
        debug($companyRevenues);
    }


    if( $this->request->is('ajax') )
    {
        $company = $this->Companies->patchEntity($company, $this->request->data);

        $company->company_last_updated = date("Y-m-d H:i:s");

        $ajaxRespArr = array();
        if( $this->Companies->save($company) )
        {
            $ajaxRespArr["result"] = 1;
        }
        else
        {
            $ajaxRespArr["result"] = 0;
        }
        $this->set( 'ajaxRespArr',$ajaxRespArr );
        $this->set('_serialize', ['ajaxRespArr']);
    }
    else
    {
        $this->set('company', $company);
    }
}

我认为错误是由于我的表company_revenues中的_。

任何人都可以指导我吗？

实际上，在配置文件操作中，我不想单独加载公司收入，因为它们与公司一起出现。

我最初尝试了以下内容：

 \plugins\Admin\src\Controller\CompaniesController.php (line 92)

object(Cake\ORM\Query) {
(unable to export object: CompanyRevenues is not associated with Currencies)
 }

但那会给出错误：

$company = $this->Companies->find()
            ->where(['company_id' => $id])
            ->contain(
                    [
                        'CompanyRevenues' => ["Currencies"]
                    ])->first();

Answer 1

我建议添加反向关系，看看会发生什么。通过反向关系，我的意思是属于您的货币和公司收入类。

货币属于公司收入和
公司收入属于公司类。
