I had issue to delete a persisted task on rails 6. I could make it work by adding a hidden_field to pass the :id of the task to delete. I don't know if it was the unique reason of my problem but if it can help :
<%- unless form.object.new_record? -%>
<%= form.hidden_field :id -%>
<%- end -%>

Great episode! I already use Docker for local development and I love it. Are you planning to do an episode to explain how to deploy a dockerized rails application? It seems very obscure to me.
