Laravel Eloquent 主从结果

Question

我正在使用 Laravel 5.1 只是想问一下当子 return 没有主数据未显示

时如何显示 ORM 主详细信息

这是我的大师模型

<?php

namespace SpekWeb;

use Illuminate\Database\Eloquent\Model;

    class ProdukGroup extends Model
    {
        public $table = 'product_group';
        public $primaryKey = 'prd_group';

        public function telcoProduct() {
            return $this->hasMany('SpekWeb\TelcoProduct', 'prd_group', 'prd_group');
        }
    }

童模

<?php

namespace SpekWeb;

use Illuminate\Database\Eloquent\Model;

class TelcoProduct extends Model
{
    public $table = 'telco_product';
    public $primaryKey = 'tel_prd';
}

这是我的控制器

<?php

namespace SpekWeb\Http\Controllers;

use Illuminate\Http\Request;
use SpekWeb\Http\Requests;
use SpekWeb\Http\Controllers\Controller;
use SpekWeb\ProdukGroup;
use SpekWeb\TelcoProduct;

class ProdukController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $memberPrices = ProdukGroup::with(array(
            'telcoProduct' => function($tpJoin) {
                $tpJoin->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
                $tpJoin->where('charge','>=',0);
                $tpJoin->whereMemType('1'); //variabel
                $tpJoin->where(function($qWhere) {
                    $qWhere->whereKodeKec('ASTAY'); //variabel
                    $qWhere->orWhereNull('cluster_gid');
                });
            },
            )
        )
        ->has('telcoProduct')
        ->get();
        return $memberPrices;
    }
}

我希望在 'with' 区域内过滤代码时不显示主记录，使用 ->has('telcoProduct) 仍然对我不起作用。主记录仍然显示在 Blade Views 上。有什么技巧可以解决这个问题吗？

Answer 1

在 with 之前添加一个 whereHas 函数。这本质上就像说 "if you have any, give me all records matching these criteria".

您的查询应如下所示（未测试）。

public function index()
{
    $memberPrices = ProdukGroup::whereHas('telco_product', function($query) {
            $query->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
            $query->where('charge','>=',0);
            $query->whereMemType('1'); //variabel
            $query->where(function($qWhere) {
                $qWhere->whereKodeKec('ASTAY'); //variabel
                $qWhere->orWhereNull('cluster_gid');
            });
        },
        )
    )
    ->with(array(
        'telcoProduct' => function($tpJoin) {
            $tpJoin->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
            $tpJoin->where('charge','>=',0);
            $tpJoin->whereMemType(1); //this value replace by dynamic Input
            $tpJoin->where(function($qWhere) {
                $qWhere->whereKodeKec('ASTAY'); //this value replace by dynamic Input
                $qWhere->orWhereNull('cluster_gid');
            });
        },
    ))
    ->get();
    return $memberPrices;
}

Answer 2

谢谢@Tim

但是当我像你说的那样使用这段代码时：

    $memberPrices = ProdukGroup::whereHas('telcoProduct', function($tpHas){
            $tpHas->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
            $tpHas->where('charge','>=',0);
            $tpHas->whereMemType(1); //this value replace by dynamic Input
            $tpHas->where(function($qWhere) {
                $qWhere->whereKodeKec('ASTAY'); //this value replace by dynamic Input
                $qWhere->orWhereNull('cluster_gid');
            });
        }
    )
    ->with(array(
        'telcoProduct' => function($tpJoin) {
            $tpJoin->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
        },
    ))
    ->has('telcoProduct')
    ->get();
    return $memberPrices;

我得到了这个结果：

"prd_group": 1,
"grp_name": "Telkomsel",
"topup_code": "777",
"balance_code": "776",
"tel_id": 1,
"product_type": "reguler",
"with_code": 1,
"telco_product": [
    {
        "tel_prd": 4,
        "prd_group": 1,
        "prd_value": 5000,
        "stock": null,
        "keyword": "S5",
        "charge": 0,
        "price": 5000,
        "mem_type": 1,
        "prd_id": 4,
        "cluster_gid": null,
        "kode_kec": null
    },
    {
        "tel_prd": 4,
        "prd_group": 1,
        "prd_value": 5000,
        "stock": null,
        "keyword": "S5",
        "charge": 0,
        "price": 5100,
        "mem_type": 2,
        "prd_id": 4,
        "cluster_gid": null,
        "kode_kec": null
    },
]

请检查telco_product的第二条记录，不符合查询条件

$tpHas->whereMemType(1);

显示telcoProduct join里面的所有记录wd_productprice

然后我尝试了这段代码：

    $memberPrices = ProdukGroup::whereHas('telcoProduct', function($tpHas){
            $tpHas->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
            $tpHas->where('charge','>=',0);
            $tpHas->whereMemType(1); //this value replace by dynamic Input
            $tpHas->where(function($qWhere) {
                $qWhere->whereKodeKec('ASTAY'); //this value replace by dynamic Input
                $qWhere->orWhereNull('cluster_gid');
            });
        }
    )
    ->with(array(
        'telcoProduct' => function($tpJoin) {
            $tpJoin->join('wd_productprice','telco_product.tel_prd','=','wd_productprice.tel_prd');
            $tpJoin->where('charge','>=',0);
            $tpJoin->whereMemType(1); //this value replace by dynamic Input
            $tpJoin->where(function($qWhere) {
                $qWhere->whereKodeKec('ASTAY'); //this value replace by dynamic Input
                $qWhere->orWhereNull('cluster_gid');
            });
        },
    ))
    ->has('telcoProduct')
    ->get();
    return $memberPrices;

结果如我所料

"prd_group": 1,
"grp_name": "Telkomsel",
"topup_code": "777",
"balance_code": "776",
"tel_id": 1,
"product_type": "reguler",
"with_code": 1,
"telco_product": [
    {
    "tel_prd": 4,
    "prd_group": 1,
    "prd_value": 5000,
    "stock": null,
    "keyword": "S5",
    "charge": 0,
    "price": 5000,
    "mem_type": 1,
    "prd_id": 4,
    "cluster_gid": null,
    "kode_kec": null
    },
    {
    "tel_prd": 4,
    "prd_group": 1,
    "prd_value": 5000,
    "stock": null,
    "keyword": "SS5",
    "charge": 0,
    "price": 5000,
    "mem_type": 1,
    "prd_id": 148,
    "cluster_gid": 3,
    "kode_kec": "ASTAY"
    }
]

我的技术正确吗？我应该在查询中写两次条件吗？
