Hello David,

Nice episode, thank you for that. I have an issue with insert_at method. I get an error undefined method `insert_at' for nil while updating the post under list. In effect when I drag and drop items, they do not remember their positions and come to the original one after refresh. Could you help here?

Kind regards,
Rafal
