Rails - Dec 2005 - Navigation

Greetings,

I appreciate the help from here as I seem to be asking the noob 
questions a lot, but what is a good way to deal with navigation pulled 
from a database?

I have this in my view:

<% @nav_buttons.each do |nav_button| %>
        <li><a href="#" class="nav"><%=h
nav_button.name %></a></li>
<% end %>

this in my controller

def index
        shownav
    end
    def shownav
        @nav_buttons = NavButton.find(:all)
    end

and I want to make it so that one of the class="nav" list items has an
id="active" decided by a default variable for the homepage, which I
will
assign a value to as another section is clicked.  I realize this is 
probably pretty micky mouse for most on this list, but I promise once I 
am up to speed on rails a bit more I''ll help the new guys around here
:-)

Cheers,

Jason

Hi Jason,

I''ll give this a shot:

Let''s say you store the active button name in a variable called
@active_button_name.

In your view, you could just add this into the href link:

  <%= ''id = "active"'' if nav_button.name ==
@active_button_name %>

So, this would change your view code to:

<% @nav_buttons.each do |nav_button| %>
  <li><a href="#" class="nav" <%= ''id =
"active"'' if nav_button.name
== @active_button_name %>><%=h nav_button.name
%></a></li>
<% end %>
