調用未定義的方法Illuminate \ Database \ Query \ Builder :: save（） - Laravel 5

Question

我弄不明白。我認爲它碰到我的activateAccount控制器功能時會發生。在那個函數裏我調用了account_activated函數，在這個函數中用戶被保存。另外，我得到了用戶對象的第一個實例，所以我沒有發生什麼錯誤。

這是控制器功能

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; 
    } 

這是錯誤味精

Answer 1

，你得到是不是從你調用函數來的錯誤，但activateAccount函數內本身。

特別是這裏這些行：

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

你需要給你的where子句後取模型。通過它的外觀你已經知道如何做到這一點，但出於完整性的考慮，你只需要在->first()補充：

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