在laravel中如何在单个视图中显示来自两个不同模型的值

问题描述投票：0回答：1

我创建了单个视图文件，并且我有多个模型，我将在视图中显示多个模型的值

我想使用“学生模型”显示学生详细信息，以及使用“中心模型”显示中心代码]]

我尝试过，但显示错误

属性[center_code]在此集合实例上不存在。（查看：C：\ center.swasthikindia.com \ resources \ views \ Center \ registretion_form_hardcopy.blade.ph

我的第一模范生

<?php

namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Database\Eloquent\Model;

class Student extends Model
{
    protected $table = 'student_lists';


    protected $fillable = ['student_name', 'student_registration_id', 'date_of_join', 'student_phone_no',];


}
我的第二名模范生

<?php

namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Database\Eloquent\Model;

class Center extends Model
{
    protected $table = 'centers';
    protected $fillable = ['center_code','center_name'];

}
}

我的路线

 Route::get('registretion_form_hardcopy{id}', 'StudentController@registretion_form_hardcopy');
我的控制器

        public function registretion_form_hardcopy($id)
{
  $hardcopy = Student::where('delete_status','NOT DELETED')->where('center_accepting_online_application','ACCEPTED')->where('center_approved','APPROVED')->where('center_code','=',Auth::user()->center_code)->find($id);

  $center_details_hardcopy = Center::where('center_code','=',Auth::user()->center_code)->get();

  $pdf = PDF::loadView('Center.registretion_form_hardcopy', compact('hardcopy','center_details_hardcopy'))->setPaper('a4', 'portrait');

  $fileName = $hardcopy->student_registration_id;
  return $pdf->stream($fileName . '.pdf');
}

您将在控制器中获得多个集合，因此请使用first()而不是get()

更改

控制器

$center_details_hardcopy = Center::where('center_code','=',Auth::user()->center_code)->first();
更改
刀片文件
{{$center_details_hardcopy->center_code ?? ''}}

php laravel laravel-5 laravel-5.7
