Hi Mehmet! That's great to hear! I had tried accomplishing this via lifecycle hooks, and then via setters, and found that it was really hard to cover all the edge cases, and that it felt like I was fighting with the functionality in .accepts_nested_arguments_for. Glad to hear that its not just me who has a use for this. Knowing that you're using it, I'll fill out the Travis testing matrix to test more rubies and rails, instead of just the combo my app is using.
