Error with after_destroy_commit using broadcast_replace_later_to with Turbo Streams

Question

iv been tryna implement turbo streams with friend request system and i have the following code in place:

 # models/friend_request.rb
  after_create_commit do 
    broadcast_friend_request_form_replace
  end
  
  after_destroy_commit do 
    broadcast_friend_request_form_replace
  end
 
  private
 
  def broadcast_friend_request_form_replace
    # Sends a replace broadcast to the Sender's stream, targeting the Receiver's turbo frame to perform the form changes.
    broadcast_replace_later_to [self.sender.id, self.receiver.id], target: dom_id(self.receiver), partial: "users/friend_request_form", 
      locals: { logged_in_user: self.sender, user: self.receiver, friend_request: self }
 
    # Sends a replace broadcast to the Receiver's stream, targeting the Sender's turbo frame to perform the form changes.
    broadcast_replace_later_to [self.receiver.id, self.sender.id], target: dom_id(self.sender), partial: "users/friend_request_form", 
      locals: { logged_in_user: self.receiver, user: self.sender, friend_request: self }
  end

The feature works with after_create_commit callback, however im having this error when trying to do it for the after_destroy_commit callback: Discarded Turbo::Streams::ActionBroadcastJob due to a ActiveJob::DeserializationError.

To my understanding, the error maybe related to the fact that, since im using broadcast_replace_later_to instead of broadcast_replace_to, it enqueues a background job to be done at a later time and when that happens the object (self) no longer exists and therefore I'm receiving the DeserializationError error.

I have tried using broadcast_replace_to instead but that makes it synchronous and what happens is that only the first callback executed after a page refresh/reload will work, not both.

Yes you are right, the reason is indeed that the object no longer exists. You can do it however. Just create the job directly like this:

after_destroy_commit do
  Turbo::Streams::ActionBroadcastJob.perform_later(stream, action:, target:, **rendering)
end
