ruby on rails - Dependent destroy not working for STI class -

i facing issue when trying destroy using nested attribute sti classes in rails 4. eg:

class < activerecord::base end  class b <   has_many :options   accepts_nested_attributes_for :options, :allow_destroy => true end

when try delete options not being deleted event has marked_for_destruction? true, option not being deleted.

i have correct paramaters accessible :id, :name, :_destroy.

i made working moving nested attributes code , has_many base class.

class < activerecord::base   has_many :options   accepts_nested_attributes_for :options, :allow_destroy => true end  class b <  end

i think issue sti in rails same can not update type of sti class object(there workaround fix that).
