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

Question

我无法弄清楚.我认为它发生在我的activateAccount控制器功能上.在该函数内部,我调用account_activated函数来保存用户.另外,我正在获取用户对象的第一个实例,所以我没有错.

这是控制器功能

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

您获得的错误不是来自您调用的activateAccount函数,而是来自函数本身.

特别是这些线:

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

您需要在给出where子句后获取模型.从它的外观来看,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();
                }
