Laravel 使用同步方法的 wherePivot 不起作用

Question

我正在尝试同步数据但出现错误。

SQLSTATE[HY000]: General error: 1364 Field 'model_type' doesn't have a default value (SQL: insert into model_has_roles (dealer, dealership_id, model_id, role_id) values (1, 61, 85, 13))

//控制器代码

$user = User::findOrFail($id);
        $user->first_name = $request->get('first_name');
        $user->last_name = $request->get('last_name');
        $user->phone = $request->get('phone_no');
        $user->title = $request->get('title');
        $user->mobile = $request->get('mobile');
        $user->save();

        $user->dealerRoles()->wherePivot('dealership_id', session('dealership_id'))->sync([$request->get('role_id') => ['dealer' => true, 'dealership_id' => session('dealership_id')]]);

// 用户模型

public function dealerRoles()
{
    return $this->belongsToMany(Role::class, 'model_has_roles', 'model_id', 'role_id');
}

您需要添加到同步方法

$user->dealerRoles()
              ->wherePivot('dealership_id', session('dealership_id'))
                  ->sync([
                       $request->get('role_id') => [ 
                            'model_type' => 1, 
                            'dealer' => true, 
                            'dealership_id' => session('dealership_id')
                   ]
        ]);
