      my model in short:

      class Event
  ...
  has_many :dates, class_name: 'EventDate'
  accepts_nested_attributes_for :dates, allow_destroy: true
  ...
end

      when i perform assign_attributes modifying some data like this (the time has changed for date at index 0):

      params = { "dates_attributes"=>{"0"=>{"starts_at"=>"2015-04-30 20:01", "_destroy"=>"0", "id"=>"553a063469702d0741050000" }}}
event.assign_attributes params

      the change is persisted to the database which is unexpected
