(1/1) FatalThrowableError

。

Sellモデル

<?php namespace App; 

use Illuminate\Database\Eloquent\Model; 
use Illuminate\Database\Eloquent\SoftDeletes; 

class Sell extends Model 
{ 
    use SoftDeletes; 

    /* The attributes that are mass assignable. 
    * 
    * @var array 
    */ 
    protected $fillable = [ 
    'employee_id', 'product_id', 
    ]; 

    const UPDATED_AT = null; 

    public function Employee() 
    { 
    return $this->belongsTo(Employee::class)->withTrashed(); 
    } 

    public function Product() 
    { 
    return $this->belongsTo(Product::class)->withTrashed(); 
    } 

    public function Install() 
    { 
    return $this->hasOne(Install::class); 
    } 
} 

私は外にuse SoftDeletes;を削除した場合、それはすべてのエラーを取得できませんでした。 私のsellsテーブル、既にdeleted_atの列があります。モデルにprotected $dates = ['deleted_at'];を追加しても問題ありません。

<?php namespace App\Http\Controllers; 

use Validator, Entrust; 

use Illuminate\Http\Request; 
use Illuminate\Support\Facades\DB; 

use App\Employee; 
use App\Product; 
use App\Position; 
use App\Sell; 

class SellController extends Controller 
{ 

    ... 

    public function destroy(Request $request, $id) 
    { 
    if (!Entrust::can('sell-delete')) { abort(403); } 

    DB::beginTransaction(); 
    Sell::find($id)->Install()->delete(); //This line was not problem. 
    Sell::destroy($id); //This line has a problem 
    DB::commit(); 

    $request->session()->regenerateToken(); 

    return redirect()->back(); 
    } 
}
