Question

我有带有hasMany OrderProducts模型的Orders模型。下面是我的代码。我使用DataTable jquery插件添加了搜索功能。每个OrderProducts包含ref_code。

我想添加搜索，例如获取包含ref_code GWG-SC-001（B）或任何用户在搜索字段中输入的OrderProducts的所有订单。

OrderTable.php

namespace App\Model\Table;

use Cake\ORM\Table;
use Cake\ORM\Query;
use Cake\ORM\RulesChecker;
use Cake\Validation\Validator;
use Cake\ORM\TableRegistry;
use Cake\I18n\Time;

class OrdersTable extends Table
{
    /**
     * Initialize method
     *
     * @param array $config The configuration for the Table.
     * @return void
     */
    public $actsAs = array('Containable');

    public function initialize(array $config)
    {
        parent::initialize($config);

        $this->table('orders');
        $this->displayField('id');
        $this->primaryKey('id');

        $this->addBehavior('Timestamp');

        $this->belongsTo('Users', [
            'propertyName' => 'Users',
            'foreignKey' => 'user_id',
            'className' => 'Users'
        ]);

        $this->belongsTo('OrderStatus', [
            'propertyName' => 'OrderStatus',
            'foreignKey' => 'order_status_id',
            'className' => 'OrderStatus'
        ]);

        $this->hasMany('OrderProducts', [
            'className' => 'OrderProducts',
            'foreignKey' => 'order_id',
            'className' => 'OrderProducts'
        ]);


        $this->hasMany('OrderPayments', [
            'propertyName' => 'OrderPayments',
            'foreignKey' => 'order_id',
            'className' => 'OrderPayments'
        ]);


    }
}


/**
 * [getOrdersList description]
 * @param  [type] $data [description]
 * @return [type]       [description]
 */
public function getOrdersList($data, $user_id = null)
{
    $orderelem = $data['columns'][$data['order'][0]['column']]['name'];
    $ordertype = $data['order'][0]['dir'];
    $offset = $data['start'];
    $limit = $data['length'];
    $conditions = array("Orders.payment_status <>" => 0);

    if (!empty($data['search']['value'])) {
        $like = '%' . trim($data['search']['value']) . '%';
        $like2 = $data['search']['value'];
        $orValues = array("Order Received");

        if (strpos($data['search']['value'], 'Status:') !== false) {
            $data['search']['value'] = str_replace('Status: ', '', $data['search']['value']);
            $orValues = explode("|", $data['search']['value']);
        }

        $conditions[] = array(
            "Orders.payment_status <>" => 0,
            'OR' => [
                'Users.first_name LIKE' => $like,
                'Users.last_name LIKE' => $like,
                'Users.title LIKE' => $like,
                'Orders.order_number LIKE' => $like2,
                //'Orders.quantity_count LIKE'    => $like2,
                //'Orders.all_total LIKE'         => $like2,
                'Orders.tracking_number LIKE' => $like,
                'OrderStatus.title' => $like,
                'OrderProducts.ref_code' => $like, // this is not working
            ]
        );
        if (!empty($orValues)) {
            $conditions[0]['OR']['OrderStatus.title IN'] = $orValues;
        }
    }

    $data2 = $this->find('all')
        ->select([
            'id', 'order_number', 'order_type', 'created', 'tracking_number',
            'delivery_methods_id', 'order_status_id', 'quantity_count',
            'all_total', 'payment_status', 'is_allow_final_payment'
        ])
        ->contain([
            'Users' => function ($u) {
                return $u->select(['title', 'first_name', 'last_name']);

            },
            'OrderStatus' => function ($os) {
                return $os->select(['status' => 'OrderStatus.title']);
            },
            'OrderProducts'
        ]);

    if ($user_id) {
        $data2 = $data2->where(['user_id' => $user_id])->andWhere($conditions);
    } else {
        $data2 = $data2->where($conditions);
    }

    $data2 = $data2->limit($limit)
        ->order([$orderelem => $ordertype])
        ->offset($offset)
        ->toArray();

    return $data2;
}

当我尝试这个时，它给出了以下错误：

“message”：“[PDOException] SQLSTATE [42S22]：找不到列：1054在where子句中的未知列OrderProducts.ref_code

请在这个问题上帮助我。

当您使用'contains'时，它实际上通常会为包含的模型生成单独的查询。正如您所看到的，“生成的查询”实际上并不包含OrderProducts，因此在这种情况下，它会为OrderProducts生成单独的查询，然后将结果组合在一起。因此，您无法对未包含在查询中的字段进行调节。

TLDR：如果您想要针对其他模型添加条件，而不是包含OrderProducts，请改用连接。

根据您的设置，您可以为关联指定joinType至INNER。

如果没有，您可以随时按照书中的说明进行内连接： https://book.cakephp.org/3.0/en/orm/query-builder.html#using-innerjoinwith

使用hasMany模型Cakephp3
