在laravel上更新記錄不止一次

Question

我正在嘗試更新laravel中的值。我有一個userupdate配置文件api，我可以用給定的參數和它們的值第一次更新值，但是當我更新相同的值時，它給我的用戶配置文件不存在。

我的代碼是：

public function UpdateUserProfile(Request $request) 
    { 

    $id = $request->input('id'); 
    $client_gender = $request->input('client_gender'); 
    $client_age = $request->input('client_age'); 
    $client_weight = $request->input('client_weight'); 
    $client_height = $request->input('client_height'); 
    $client_dob = $request->input('client_dob'); 

    $profile= DB::table('clients') 
     ->where('id',$id) 
     ->update(['client_gender'=>$client_gender,'client_age'=>$client_age,'client_height'=>$client_height,'client_weight'=>$client_weight,'client_dob'=>$client_dob]); 
    if($profile) 
    { 
     $resultArray = ['status' => 'true', 'message' => 'User profile updated Successfully!']; 
     return Response::json($resultArray, 200); 
    } 
     $resultArray = ['status' => 'false', 'message' => 'User profile does not exist!']; 
     return Response::json($resultArray, 400);} 

當我更新的價值它給了我這樣的響應第一次：

{ 
"status": "true", 
"message": "User profile updated Successfully!" 
    } 

，當我打通過郵遞員的更新請求它給出了一個400錯誤的請求和響應是：

{ 
"status": "false", 
"message": "User profile does not exist!" 
}

我建議重寫該函數看起來像th以下;主要是因爲它讀得更好，並使用Laravel中更常見的模型方法

public function UpdateUserProfile(Request $request) 
{ 
    // this code fails if there is no client with this id 
    $client = App\Client::findOrFail($request->id); 

    // attach new values for all of the attributes 
    $client->client_gender = $request->input('client_gender'); 
    $client->client_age = $request->input('client_age'); 
    $client->client_weight = $request->input('client_weight'); 
    $client->client_height = $request->input('client_height'); 
    $client->client_dob = $request->input('client_dob'); 

    // save 
    $client->save(); 
    return ['status' => 'true', 'message' => 'User profile updated Successfully!']; 
}
