self-reference association

[Carlos Betancourt C.]

Hi!

We have a comment model that can have many comments as childrens.

...

      has_many :childrens, class_name: self.to_s, foreign_key: :parent_id

      belongs_to :parent, class_name: self.to_s, foreign_key: :parent_id

...

In it's factory, we have a trait to handle this associations, so we can create a comment with many children comments.

...

    trait :with_childrens do

      after(:create) do |comment|

        create_list(:comment, parent: comment)

      end

    end    

...

But it a exception is raised: "FactoryGirl::AssociationDefinitionError: Self-referencing association 'parent' in 'comment'"

How can we treat this?

Regards,
