Php Laravel雄辩的大师级细节成果

Php Laravel雄辩的大师级细节成果,php,laravel,eloquent,relationship,laravel-5.1,Php,Laravel,Eloquent,Relationship,Laravel 5.1,我使用的是Laravel 5.1 只想问一下,当子级未返回主数据未显示的数据时,如何显示ORM主数据详细信息 这是我的主模型 <?php namespace SpekWeb; use Illuminate\Database\Eloquent\Model; class ProdukGroup extends Model { public $table = 'product_group'; public $primaryKey = 'prd

我使用的是Laravel 5.1 只想问一下,当子级未返回主数据未显示的数据时,如何显示ORM主数据详细信息

这是我的主模型

<?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');
        }
    }
子模型

<?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;
    }
}
当我使用->has'telcoProduct过滤“with”区域内的代码时,我希望主记录不显示,但它仍然不适用于我。主记录仍显示在刀片视图上。 有什么技巧可以解决这个问题吗?

在使用之前添加whereHas函数。这基本上就像是说,如果你有,给我所有符合这些条件的记录

您的查询应该是这样的: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;
}
Thanx@Tim

但当我像你说的那样使用这个代码时:

    $memberPrices = ProdukGroup::whereHas('telcoProduct', function($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_group": 1,
        "prd_value": 5000,

    },
]
请检查电信产品的第二条记录,它与查询条件不匹配

$tpHas->whereMemType1

它显示telcoProduct join wd_productprice中的所有记录

我尝试了以下代码:

    $memberPrices = ProdukGroup::whereHas('telcoProduct', function($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;
我得到了我预期的结果

"grp_name": "Telkomsel",
"topup_code": "777",
"balance_code": "776",
"tel_id": 1,
"product_type": "reguler",

    {

    }
]
我的技术正确吗?我应该在查询上写两次条件吗


Thx

修改后的查询只返回ProdukGroup数据。我希望$memberPrice也返回其子记录。请参阅我更新的帖子。whereHas只检查特定条件,但不立即加载它们。是的,不幸的是,这是正确的。这些条件不共享,因此您必须使用whereHas筛选出所有父对象,然后使用加载它们。谢谢你指出我代码中的缺陷,我会更新的。
