Because we ended up with such a big error, and it doesn't have an easy
fix, I'm wrapping up today by reverting the entire set of refactors
we've done lately, so modeling in production can continue while we
improve this code further over time.
I generated this commit by hand-picking the refactor-y commits
recently, running `git revert --no-commit <hash>` in reverse order,
then manually updating `pet_spec.rb` to reflect the state of the code:
passing the most important behavioral tests, but no longer passing one
of the kinds of annoyances I *did* fix in the new code.
```shell
git revert --no-commit 48c1a58df9
git revert --no-commit 42e7eabdd8
git revert --no-commit d82c7f817a
git revert --no-commit 5264947608
git revert --no-commit 90407403ba
git revert --no-commit 242b85470d
git revert --no-commit 9eaee4a2d4

```
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!
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!
The NC Pet Styles sentence getting broken across two lines I think
makes it too hard to notice.
Design-wise, it would be nice to just call better attention to this
feature altogether in some higher-level design-language-y way, but!
Whatever!
If you check this box, it'll keep you in a mode where saving an alt
style redirects you to the *next* one that needs labeling, until
they're all done. Useful for big drops!
Catch missing fields in validation before sending it to the DB, and
skip the Dyeworks stuff if the name is missing.
I ran into this looking into `test/trade_activity_test.rb`, which fails
right now because we try to create a boring placeholder item with
minimal fields, which Dyeworks can't call `name.match()` on!
Now, the test fails with a more helpful error about the item being
invalid. Next, I'll fix that!
Just getting this stuff out of Pet, in part because I want to start
being able to unit test modeling, and that will require stubbing out
what this service returns!
Just a bit more clarity of grouping! I'm also thinking about extracting
modeling APIs into a service file like this too, in which case I think
this would help clarify what it is.
They're not all Nostalgic anymore! Oh, how the times have changed!
This way, new ones will appear as "<New?>", until support staff come in
and label them (with our cool new tools!)
Whoops, I didn't realize this change I made to validation for the alt
style editing form, was goofing up alt style modeling!
The trick is, the validation was happening before the `before_create`
hook. Now I've reformulated these as `before_validation` hooks, so
we're not rejecting new alt styles for having no thumbnail!
