Well, that’s not really enough to go on. Take a look at the
restful_authentication plugin or follow along with Agile Web
Development with Rails for that kind of thing.

Where is the l method defined? Is that where your NoMethodError comes
from?

Also, don’t user the @session or @params variables, use the session
and params methods instead:

if session[‘user’] = User.authenticate(params[‘user’][‘username’],
params[‘user’][‘password’])
