Question

我有两张像这样的表

empPf

id
emp_id
emp_name
uan
kyc

empyc

id
emp_id
doc_type
doc_number

现在我有两个模特

empPf

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class empPf extends Model
{
    protected $table = 'empPf';
    protected $primaryKey = 'emp_id';

     public function kyc(){

            return $this->hasMany('App\empKyc','emp_id');

        }
}

empKyc

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class empKyc extends Model
{
    protected $table = 'empKyc';
    //protected $primaryKey = 'emp_id';

     public function pf(){

            return $this->belongsTo('App\empPf','emp_id');

        }
}

我正在尝试在我的控制器中执行以下代码

public function getPf(){
        Session::put('activemenu', 'emp_ss');

        $pfs = empPf::with(array('kyc'))->get();

        foreach ($pfs as  $value) {
              dd($value->kyc[0]->emp_id);
        }

    }

我收到错误

尝试获取非对象的属性

任何帮助将不胜感激

Answer 1

您必须首先检查 pfs 模型是否有任何相关的 kyc ：

foreach ($pfs as  $value) {
    if ( $value->kyc->count() ) {
        dd( $value->kyc[0]->emp_id );
    }
}
