调用未定义的方法 Illuminate\Database\Query\Builder::save()- Laravel 5

Question

我想不通。我认为它发生在我的 activateAccount 控制器函数上。在该函数中，我调用了保存用户的 account_activated 函数。另外，我得到了用户对象的第一个实例，所以我不知道出了什么问题。

这是控制器函数

public function activateAccount(Request $request, User $user, $key) {
    $registered = $request->session()->get('registered');
    if (isset($registered)) {
        $request->session()->forget('registered');
        if ($user->account_activated($key)) {
            // TODO 
            $referral = Referrals::where('activation_key', $key);
            if (!empty($referral)) {
                $referral->validate = 1;
                $referral->save();
            }


            return redirect('/login')->with('success', "Your account has been activated. You many login!");
        } else {
            return redirect('/not-active');
        }
    } else {
        return redirect('/');
    }
}

account_activated function inside the User model
    public function account_activated($key){
      $user = User::where('activate_key', $key)->first();
      $user->activate = 1;
      $user->save();
      return true;
    }

这是错误消息

您遇到的错误不是来自您调用的函数，而是 activateAccount 函数本身。

特别是这里的这些行：

$referral = Referrals::where('activation_key', $key);
            if (!empty($referral)) {
                $referral->validate = 1;
                $referral->save();
            }

您需要在提供 where 子句后获取模型。看起来你已经知道如何做到这一点，但为了完整起见，你只需要添加一个 ->first():

$referral = Referrals::where('activation_key', $key)->first();
                if (!empty($referral)) {
                    $referral->validate = 1;
                    $referral->save();
                }

调用未定义的方法 Illuminate\Database\Query\Builder::save()- Laravel 5
