シルバーストライプが選択後にオブジェクトに保存されない

Question

フィルタを使用してオブジェクトを選択した後にデータベースに挿入したいとします。ここで

は私のコードです：

$dayMealType = $newCustomer->Diets()->first()->DietMealPlan()->first()->Days()->filter('Order',$request->postVar('updateData')['dayNr'])->first()->DayMealType()->filter("MealTypeID",$request->postVar('updateData')['MealTypeId'])->first()->Foods(); 
$food_tmp = new FoodMealPlan(); 
$food_tmp->Carbohydrates = $request->postVar('updateData')['carbohydrates']; 
$dayMealType->add($food_tmp); 
$dayMealType->write(); 

選択作品と、それは以下のようなオブジェクトを返す：食品と

object(ManyManyList)#102 (16) { 
    ["joinTable":protected]=> 
    string(17) "DayMealType_Foods" 
    ["localKey":protected]=>

クラスは、このようなものです：

class DayMealType extends DataObject 
{ 
    private static $db = array(
     'Calories' => 'Int', 
     'Carbohydrates' => 'Int', 
     'Proteins' => 'Int', 
     'Lipids' => 'Int', 
     'Price' => 'Decimal' 
    ); 

     private static $has_one = array(
     "MealType" => "MealTypeDetails", 
     "DayDietMealPlan" => "DayDietMealPlan" 
    ); 
     private static $many_many = array(
     "Foods" => "FoodMealPlan" 
    ); 

     private static $casting = array(
     'FoodsList' => 'HTMLText' 
    ); 

それ関数write（）の後にエラーを返します。

DBには書き込まれません。

リレーションシップを追加する前に、FoodMealPlanをデータベースに保存する必要があります。

$food_tmp = new FoodMealPlan(); 
$food_tmp->Carbohydrates = $request->postVar('updateData')['carbohydrates']; 
$food_tmp->write(); // Saves to the database 
$dayMealType->add($food_tmp); 
$dayMealType->write();
