Remove association model in Rails

问题

Hi i would like to know if its possilbe to remove an association in rails.

Well, i have something similar to this:

class Home < ActiveRecord::Base
  include settings
end

On settings.rb i have something similar to this

module Settings
  attr_reader :person
  attr_reader :address

  def self.included(base)
      base.belongs_to :city
      base.belongs_to :entity
      [...]
  end

  [...]

end

On Home class the city model association on my particular case don't make sense. And i have to find a way to remove it to maintain my code DRY.

Thank you!

If you just don't want the methods then use remove_method to remove them.
