ruby on rails - Alert messages do not always show up on production (Heroku) -


There is a bit of code from the controller here: 

  flash [: warning] = "please specify input" redirect_to (root_url)

And I present it with the following code in application.html: 

 ! - Display Notices - & gt; & Lt; Div class = "& lt;% = 'shift_no_breadcrumb' if yield (: crumbs) .blank?% & Gt;" & Gt; & Lt;% Flash. Key, value | & Gt%; & Lt;% = content_tag (: div, value ,: class = & gt; ("alert alert - # {key}"))% & gt; & Lt;% end% & gt; & Lt; / Div & gt;

It looks very spatial on production. Out of 10 attempts to perform the same exact action, the message can be seen anywhere from 3 to 6 times. I also checked the source code and can verify that the message sometimes appears and sometimes Does not happen. Is there anything in the order in which the assets are full? I am very worried about this issue .... Does anyone have any information about what is behind this?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. 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
