amazon web services - Required attribute in Dynamo.DB -


I have dynamo I am using DB and following for node. JS; I was wondering how can I be an attribute as "necessary"?

Here I got an example in the document, but I'm not sure that we can have the "required" attribute in the dynamo. DB or not? 

  // Jason object var items based on [string, number, string array, or number array] {Score: 304, Date: (new date) .getTime (), Sha: '3d2d6963 ', USR:' Spolu ', LNG: [' node ',' C ++ ']}; Ddb.putItem ('a-table', item, {}, function (err, res, cap) {});

I do not think you can only do primary keys, because dynamody 'Schema-less', it does not really understand that the schema-less database has the required attribute on the field.

Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
