Rails - Sep 2005 - Nuby question concerning layouts / components / partials

I''m prototyping an app that has a basic 3 column layout, with the left
column being for logging in. Once the user is logged in, the right
column should disappear and the left should change to information
about who is logged in, etc. Being new to rails, I am struggling a bit
with the best way to approach this. I started down the path of
componentizing the login box, but then became confused as to where to
locate the user model that is associated with the login (I have
implemented the login using the basic login generator from the wiki).
What I have right this instant is an application layout that handles
switching content based on whether the user is logged in.

Is this the best way to go, or should I pursue the component route?
Partials? Changing layouts?

TIA,
Keith

I''m new to this as well but I suppose I would have conditionally
inserted a partial depending on whether the user is logged in.

That''s the way I was leaning.  I''m trying to use style sheets
for all
of the layout, so I guess I would have each partial have a different
(div) ID (to allow for different positioning)? I''m getting close to
the results I want, but am having a bit of a time keeping track of
where information is best kept: style sheets, partials, layouts,
views. Guess I''ll figure it out over time. :-) Anyway, thanks for the
input.

There''s many ways you could do this:

<%= render :partial => (logged_in? ? ''login_column'' :
''other_column'') %>

Or

<%= render(:partial => ''login_column'') if logged_in?
-%>
<%= render(:partial => ''other_column'') unless logged_in?
-%>

Keith-
     The way I am doing stuff like you are trying to do is to  
conditionally use the render_component call in the views but I don''t  
bother with the actual components directory. You can just use the  
render_component call with _any_ controller and action. The only  
thing to remember is to use the render_without_layout call in the  
action. If you have any other views that use the same action with a  
layout you can do something like this:

# renders a minimal print layout when called by an url that  
includes : /controller/vo/23?print=1
             def vo
               if params[:print]
                 render :layout => "print_version" &&
return
             else
                 @params
                 render :layout => "voice_tmpl"
               end
             end

# or use the same thing to render without layout:
# call with /controller/vo2/24?inc=true
             def vo2
               if params[:inc]
                 render :layout => false && return
             else
                 @params
                 render :layout => "voice_tmpl"
               end
             end

     This might not be exactly what you want but take a look here :  
<http://yakimaherald.com> I use this type of stuff to render the side  
bars and other little components. You can call them in your views  
like so:

<%= render_component :controller =>"page", :action =>
"vo", :params
=> { :inc => "true" } %>

Hope that helps some-
