I’m using the login\_generator and with this new version of Rails, I  
can’t even get my app to work. Everything gives a 500 error. In the  
console, it says this error:

undefined method `model’ for ApplicationController:Class

In the login\_generator plugin, you’re supposed to put this command in  
the application controller:

model :user

When I took it out, it complained about something else…something to  
do with secrets. So how can I fix this? ☹

That’s something else. The default session store is the cookie store  
in rails 2.0, which requires you to define a secret in your  
environment.rb.

i.e.  
config.action\_controller.session = {  
:session\_key =\> ‘\_empty\_app\_session’,  
:secret =\> ‘your secret here’  
}

If you generate a new app rails will create a nice long safe secret  
for you. You can run  
rake secret  
to get rails to generate you a nice secret.
