Rails doesn't see methods in Models

After switching to Mac OSX 10.4.8 and latest edge. My project stop
working. It had to works great before!! For example i have a login
page:
after entering login and password rails says, that it can't find
method
short_name in my model (it's exist and i can access it from rails
console). It also can't find any associations. I really don't know
what to
do. I've tried to install mongrel - nothing. My spec: Mac Book 10.4.8,
MySQL 4.1.20 - standart. Lighttpd and i also have Mongrel now..

A lot of people on here are running the same setup as you and not
having problems. It'll be an issue in your app somewhere, and without
knowing more about that we can't really help.

Cheers,
