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

I've found the solution to this issue...

I'm using Rails 3 and my class looks like this (and the problematic methods was this too)

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

I did have to hack a lot in the code to find out something was wrong with the named_scope on the line

@organizations = self.find :all, :conditions => ['is_company = ? ',true]

So I had to change it to something like this

@organizations = Organization.where("is_company = ?",true)

But it was wrong too.. So I decided to add an scope for this below the class name so the final code looks like this:

class Organization < ActiveRecord::Base
  scope :company, where("is_company = ?",true)

  def self.parents
    @organizations = self.company
    select_choice = I18n.t("select") + " "+ I18n.t("segments.description")
    @organization_parents = [select_choice]
    for organization in @organizations
      @organization_parents << [organization.name, organization.id]
    end
    return @organization_parents
  end 
  #...
end

So using this line with the scope

@organizations = self.company

it worked flawlessly in every part of the code.

I was wondering if the named_scope is deprecated when using class methods or they are not supported from now and throws an error and not a warning before

Thanks for your help Leo
