baffling undefined method

rubyonrails-talk
1

I have a model

class Person < CimHrdb   ...   belongs_to :local_province, :foreign_key => "person_local_province_id", :class_name => "Province"   ... end

(where CimHrdb extends some classes (with abstract_class = true) that eventually extend ActiveRecord::Base)

and I'm getting

A NoMethodError occurred in reports#crisis_management:

undefined method `local_province' for #<Person:0x40eec754> [RAILS_ROOT]/vendor/rails/activerecord/lib/active_record/base.rb: 1799:in `method_missing'

The confusing thing is that it happens every once in a while. It's not every time. I can't figure out why. It seems to not set up the local_province method at times. This is on a production mongrel server, btw.

Just wanted to follow up on this. I found out that it's because one of my log/mongrel.pid files got erased, so when mongrel was restarting, it couldn't kill one of them. Then it kept running with old classes loaded. So one of my three mongrels had old classes loaded, explaining why it only happened sometimes.
