As I'm writing out my solution for this, I'm almost wondering if it's
time for the refactor I've been Theoretically Planning Someday, to move
items to a real `ItemAppearance` model in the database similar to
`PetState`… Hmm hmm hmm…
For now though, I'm taking a break!
This bug never made it into production I think, it was a consequence of
some of how I refactored stuff in the recent changes? I think??
But yeah, I refactor how we manage `SwfAsset#body_id`, to be a bit more
explicit about when and how it can change, instead of the weird
callbacks that tbqh have bit us too often…
Ah right, the callbacks in `ParentSwfAssetRelationship` don't get
called when Rails does automatic join-model management stuff. We need
the `Item` to call its `update_cached_fields` callback itself, too!
When fixing this, I found a new bug that arose, in how we infer
`body_id` for assets that fit all pets. Fixing that next!
This gives better output when they fail, and also avoids spurious
failures like when an array for `cached_compatible_body_ids` is replaced
by an identical one! (I'm running into this right now, and yeah, it
helps a lot lol)
Hmm, I think I made a mistake on `modeling_snapshot.rb:69`: I'm
assigning the *entire* `item.swf_assets` relation to *just* the assets
for the new model of it, which breaks all the other connections.
First, I'm disabling modeling. Then, I'll restore a backup. Then, I'll
write tests for that case, and fix it up!
Not actually touching alt style yet, just the very basic stuff about
how alt style can cause loading to fail in certain extremely rare cases
(specifically, if it's our first time seeing the underlying
color/species combo too, which… isn't gonna happen irl on DTI for a long
time if ever, I would guess, but hey!)
That is, if everything is the same as before, we don't need to change
anything in our database!
I also learned a bit more about RSpec syntax sugars, it's cute!
I forget, there was some tricky debugging about getting the fixtures
right, I think the previous commit doesn't *actually* pass from a clean
setting. Ah well, looks good now!
Look, I'll be real, I have literally not run these automated tests in
probably like a whole decade. Most of these files are empty, the ones
that aren't seem basically trivial, and I bet half of it would fail
anyway.
If I wanted to do real automated testing, I would basically want to
start from scratch anyway, and apply coverage I can trust to the areas
I actually care about.
Until then, I feel like these gems and files are mostly just clutter,
and I don't like them being One More Barrier To Entry. Goodbye, unused
complexity!
