Hi all,
I''m trying to do a condition in my application.html.erb where if a user
is based off of a STI it has a "special" section in the navigation.
The following code correctly prints out the user type (either User or
Client)
[code]
<%= current_user.class if logged_in? %>
[/code]
However, when I try to do an if search (example below) it work at all.
[code]
<%= content_tag(:li, link_to ("Products", productss_path)) if
current_user.class == "Client" %>
[/code]
If I change "Client" in the above code to "User" it still
doesn''t work.
Is there some special case or usage required to handle
current_user.class in an if loop?
Thanks in advance!
-Tony

I get the hard stuff working but simple stuff like this gets me stuck often. Besides the craziness of the Rails API (although it IS helpful), if there a place where I can learn this kind of thing simple thing?

I was able to find the .class declaration via your search term. I guess I just didn''t know that the "current_user" part was an object. I''m telling you - simple stuff. Luckily I''ve gotten far from using basic knowledge and hacking/stitching things together until they work. I hate it though - I''d love to know my programming was solid. I''m going to dedicate a few weeks to learning the basics to avoid more embarrassing situations like these. :-) -Tony -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Actually I baulked at saying everything is an object, in some languages even the operators are objects and I think that is not the case in ruby.
