I’m not sure I understand what’s the problem, where exactly do you have doubts?
I’d suggest you first refactor that super ugly nested loops and ifs:
- remove the unnecesarry if’s
DdCategory.all.each do |category|
can’t you handle that is_active? with a scope?
the blocks for category.dd_items and subcategory.dd_items looks almost the same, I think you can reuse some code there
move complex logic to other methods to clean that up, like:
item.dd_subitems.each do |subitem|
newitem.dd_detail_subitems.create!(dd_detail_item_id: newitem.id, title: subitem.title, has_check: subitem.has_check, has_value: subitem.has_value, has_note: subitem.has_note, item_check: subitem.item_check, item_value: subitem.item_value, item_note: subitem.item_note)
could be a method on newitem like “add_subitem_from(subitem)” that does that create but you’ll have less clutter to simplify your logic to understand it better
