I am new to ROR and I am trying to retrieve data based on a session  
value I store. This is a basic app that collects user data and puts  
it in the DB. I then store the last insert id to a session variable  
on the server. This much works. The problem I am having is if that  
user comes back to the site I dont want to show them another form I  
want to show them the data they entered and I want to access the data  
in the DB via the ID I store. Also when I look at the session data on  
the server I see my ID there.

I am trying to do this in my controller (the else condition works  
fine)

def show

if session[:id]  
@something = SOMETHING.find(session[:id])  
else  
@something = SOMETHING.find(params[:id])  
end

end

My show.rhtml is simply :

\<% for column in SOMETHING.content\_columns %\>

**\<%= column.human\_name %\>:** \<%=h @something.send(column.name) %\>

\<% end %\>
