Oops, if you saved `SwfAsset` outside of modeling code, the `item` field would be empty, and so `item.body_specific?` wouldn't happen.
This would trigger when you even just report a broken image!
Now, we always run the SQL query to check for that flag.
For example, the Meerca Maid Tray is a foreground item, so the SWF is marked
as compatible with all body types, but the item itself is clearly marked as
Meercas-only. items#show reflected this properly, but the swf_assets#index
call that the wardrobe uses ignored item.species_support_ids.
So, /bodies/:body_id/swf_assets.json?item_ids[]=... was deprecated in favor
of /pet_types/:pet_type_id/items/swf_assets.json?item_ids=[]..., which is
much like the former route but, before loading assets, also loads the pet
type and items, then filters the items by compatibility, then only loads
assets for the compatible items.
Lots of scary bugs were being caused by the fact that the possibly-duplicate Neopets ID
was being treated as an SWF's real primary key, meaning that a save meant for object swf
number 123 could be saved to biology swf number 123. Which is awful.
This update gives SWFs their own unique internal ID numbers. All external lookups still use
the remote ID and the type, meaning that the client side remains totally unchanged (phew).
However, all database relationships with SWFs use the new ID numbers, making everything
cleaner. Yay.
There are probably a few places where it would be appropriate to optimize certain lookups
that still depend on remote ID and type. Whatever. Today's goal was to remove crazy
glitches that have been floating around like mad. And I think that goal has been met.
