Needs to be after the comma. Short form is better still... -- -- Tom Mornini
Yeah...I got brackets out of whack...
@sess_user = User.find(:first,
:conditions => ["id = ?", session[:user_id] ])
or
@sess_user = User.find(session[:user_id])
both still return the same error...
symbol as array index
which probably still isn''t what I want to get out of it since I
actually
want user.name from the ''find'' but nevertheless...the error is
still the
same.
Thanks
Craig

Craig, Can you show us the exact contents of your session, or show us the code for the user id being added to the session data? It sounds like there is a problem with session[:user_id] Estelle.

When I create the session, I get all the session variables I will need later rather than resorting to having to get them out of the db later. This is a simple process and it was my twisted logic that said...OK, I need this value now and the only way I can get it is from the user_id in the session. Much simpler - thanks for the concern. I am now onto rights based roles and I can see that Chad''s ''Recipes'' is gonna pay me dividends now. Thanks Craig
