Overview

Occurs when a circular reference is detected in the containing model.

  def initialize
    super()
    models << self  # Adding itself to models creates a circular reference.
  end
end
model = Model.new
model.save  #=> raises ActiveRecordCompose::CircularReferenceDetected

class Model < ActiveRecordCompose::Model
  attribute :model
  before_validation { models << model }
end
inner = Model.new
middle = Model.new(model: inner)
outer = Model.new(model: middle)

inner.model = outer  # There is a circular reference in the form outer > middle > inner > outer.
outer.save  #=> raises ActiveRecordCompose::CircularReferenceDetected
