def resolve_circular_habtm_dependencies!
  # When two models each have a `has_and_belongs_to_many` association pointing to the other,
  # it creates a circular dependency.  Based on Sprig documentation, we only need to define
  # the association in one direction
  # (https://github.com/vigetlabs/sprig#has-and-belongs-to-many), so we delete one of them.

  self.each do |(model, dependencies)|
    model.reflect_on_all_associations(:has_and_belongs_to_many).each do |association|
      if dependencies.include?(association.klass) && self[association.klass].present?
        self[association.klass] = self[association.klass] - [model]
      end
