always permit selected parameters in strong parameters in rails 4.0.8 -


I'm always trying to allow a specific parameter 'format' in strong parameters. I am currently using Rail 4.0.8

It has been included in the rail. 4.1

Rail guide suggests that it is configurable

< P> config.action_controller Always_permitted_parameters =% w (controller action format)

I'm trying to find a way around in Rail 4.0.8. Can it be achieved with some port patch?

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!
