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,
