App\Profile::jenis must return a relationship instance, but "null" was returned. Was the "return" keyword used? (View: C:\xampp\htdocs\user_manage\resources\views\profile\profile.blade.php) (View: C:\xampp\htdocs\user_manage\resources\views\profile\profile.blade.php)
Model Jenis.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use App\Profile;
class Jenis extends Model
{
public $timestamps = false;
protected $table="tbl_jenis_penyedia";
protected $primaryKey="id_jenis_penyedia";
protected $fillable=['jenis_penyedia'];
public function profile(){
return $this->belongsTo(Profile::class);
}
}
Model Profile.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Profile extends Model
{
public $timestamps = false;
protected $table="tbl_profil_penyedia";
protected $primaryKey="id_profil_penyedia";
protected $fillable=['id_jenis_penyedia','nama', 'no_ktp', 'file', 'npwp', 'bank', 'no_rek', 'email', 'no_telp', 'keahlian', 'pengalaman', 'alamat', 'pendidikan'];
public function jenis(){
$this->hasMany(Jenis::class, 'id_jenis_penyedia', 'id_profil_penyedia');
}
}
Controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use App\Profile;
use App\Jenis;
class ProfileController extends Controller
{
public function index()
{
$profile = Profile::all();
return view('profile/homeprofile',['profile' => $profile]);
}
}
view
@foreach($profile as $p)
<tr>
<td>{{ $no++ }}</td>
<td>
{{ $p->jenis->jenis_penyedia }}</td>
</tr>
@endforeach
请帮帮我
最佳答案
你忘了把 return
放在 jenis
方法中。
Profile.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Profile extends Model
{
public $timestamps = false;
protected $table="tbl_profil_penyedia";
protected $primaryKey="id_profil_penyedia";
protected $fillable=['id_jenis_penyedia','nama', 'no_ktp', 'file', 'npwp', 'bank', 'no_rek', 'email', 'no_telp', 'keahlian', 'pengalaman', 'alamat', 'pendidikan'];
public function jenis(){
return $this->hasMany(Jenis::class, 'id_jenis_penyedia', 'id_profil_penyedia'); // PUT A `return` HERE
}
}
关于php - App\Profile::jenis 必须返回关系实例,但返回了 "null"。是否使用了 "return"关键字?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/58873739/
