So it turns out this was just one of those things I forgot to fix
the big database restructure came along: we were comparing
swf_asset.remote_id against parents_swf_assets.swf_asset_id, which
are two different identifiers entirely. Now using swf_asset.id,
so fixed :)
At first I thought this was an error in the data migration process when moving SWF assets
to having their own unique IDs, but then realized that the query for a pet state's SWFs
didn't include the (parent_type = 'Item') condition. Oops. Turns out, I only connected the
items to parent_swf_asset_relationships polymorphically. Pet states were still doing it the
hackish way. Set the pet states to use the lovely polymorphic relationship and we're good
to go.
After changing the database structure, we lost the feature where, once we discover
new assets for an item for a given body ID, we disconnect previously connected
assets. This commit reinstates that feature.
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.
