Question

我在某个模型中使用SoftDeletes时出现此错误。

(1/1) FatalThrowableError

Type error: Too few arguments to function Illuminate\Database\Eloquent\Model::setAttribute(), 1 passed in /Users/ThunderBirdsX3/Desktop/Workspace/myproject/vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasAttributes.php on line 519 and exactly 2 expected

使用Sell::destroy($id);和Sell::find($id)->delete();。

Sell模型

<?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);
  }
}

如果我删除use SoftDeletes;，则不会收到任何错误。我的sells表格已经有deleted_at列。在模型中添加protected $dates = ['deleted_at'];它没有帮助。

控制器

<?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();
  }
}

数据库结构

尝试在模型中添加此内容

protected $dates = ['deleted_at'];

<强> Laravel Docs

要为模型启用软删除，请在模型上使用Illuminate \ Database \ Eloquent \ SoftDeletes特征，并将deleted_at列添加到$ dates属性

使用SoftDeletes时出错
