</div>

In the controller method I have the following:

def create  
@adv = Adv.new(params[:adv])  
@adv.save  
flash[:notice] = “Advertisement successfully created”  
redirect\_to “/advs/#{@adv.id}”  
end

When I create a new “Adv”, I DON’T get the message: “Advertisement  
successfully created”

Why is that? What am I missing?

Thanks.

The code here is setting up the flash but you have to have code in the  
view to display it. What have you got in the view that you are showing  
after the redirect?

In View have you added \<%= flash[:notice] %\>  
and \<%= javascript\_include\_tag :defaults %\>

Thanks a lot everyone.

You are correct:

Yes, I have added “\<%= flash[:notice] %\>” in “application.html.erb”

I just want to ask, how can we make that notice with a different color  
and background? Should we do this manually by HTML for example?

Thanks.

I made some changes in “application.html.erb” as follows:

\<%= flash[:notice] %\>

And it did what I was looking for.

Thanks.

Inline styling will certainly work but it has very much fallen out of  
favor. You will do yourself a favor, professional reputation-wise, by  
learning to use css selectors.

Best regards,

Change the values in the selector in application.css
