stack level too deep


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'

  has_many :documents

  validates_presence_of :name

    def self.parents       #@organizations = self.find :all, :conditions => ['is_company = ? ',true]       @organizations = Organization.where("is_company = ?",true)       #@organization_parents =       select_choice = I18n.t("select") + " "+ I18n.t("segments.description")       @organization_parents = [select_choice]       for organization in @organizations         @organization_parents << [,]       end       return @organization_parents     end
