Stack level too deep error in Ruby on Rails

Question

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.

Answer 1

The stack level too deep error occurs also, if you want to destroy a record and you have an association with :dependent => :destroy to another model. If the other model has a association with :dependent => :destroy back to this model, the stack level is too deep, too.
