I have a TodoList model and a TodoItem model. I can create the nested form and it renders in the todolist#new. It will only create a todolist title. It will accept the todo list items, but on the index page the items are not showing up. I have done a ton of research including the docs and these sources; see bottom of the post.
The form will render with no errors. But when I hit save the todo list title will save, but the items I enter will not save.
Todo List Title --This will save
Items ---This will not save
