Hi All, I am trying write a validation rule where I need to ensure that when a certain value is updated or created in a particular columns, a number of other columns columns are unique and that another column does not contain a certain value.

Given the models Country, State, City and Person as follows. class Country < ActiveRecord::Base has_many :states end class State < ActiveRecord::Base belongs_to :country has_many :cities end class City < ActiveRecord::Base belongs_to :state has_many :people end class Person < ActiveRecord::Base belongs_to :city end Is there any way that doesn''t allow to delete
