Hello...

I'm having a stack level too deep error using Ruby 1.8.7 with Rails 3.0.4 and with the rails console I performed the following commands.

leo%>rails console Loading development environment (Rails 3.0.4) ruby-1.8.7-head > leo = Organization.find(1)

SystemStackError: stack level too deep from /app/models/organization.rb:105:in `parents'
