This doesn't generally happen, but did the other day when I rolled back
some of the database's SWF asset records but kept the items—and it was
a bit confusing that the homepage marked them as fully modeled!
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.

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!
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!
Oh huh, I guess most of the new items we had when I rewrote this were
Maraquan, and I didn't test enough on standard species-specific items.
Before this change, partially-modeled items for standard pets would
appear as fully modeled, because the presence of the "nonstandard"
color Orange (because of the Orange Chia) meant that the "standard" key
didn't actually have any unique bodies (it was all `["standard", 47]`).
Here, I take my own comments' advice and move away from the standard
label as part of the logic. Instead, we look first for nonstandard
colors with unique bodies, which we'll call out as modelable; and then
check whether there are any basic bodies *not* covered by those special
colors.
That way, compatibility with the Maraquan Acara (a unique body) means
we'll treat Maraquan as a modelable color; and then we'll ignore the
basic bodies, even though it *does* fit the basic Mynci, because there
aren't any compatible basic bodies that aren't *also* Maraquan bodies.
This also means that compatibility with both the Blue Acara and Orange
Acara does *not* preclude a normal item from needing basic pets for
models: because, while Orange is a slightly nonstandard color in the
case of Chia, it doesn't have its own unique body for this item, so we
ignore it when predicting compatibility with basic colors.
Before this change, a fully-modeled item (Dyeworks Burgundy: Gown of
the Night) was displaying as still needing the Chia. This was because
looking for "standard" body IDs like this caught up some of the weird
Chia bodies.
I think there's probably something here where we need to like, relabel
certain colors? But honestly, the better version of this logic would
probably be to lean more into the `basic` label in this logic.
But hey, that's a refactor for another time. I gotta go eat!
Noticing a lot of Maraquan items on the homepage today, and they're
doing that thing of expecting standard body types to be relevant too,
because I think we wrote this logic before the Maraquan Mynci ended up
having the same standard Mynci body? (Maybe? Or maybe I'm being
ahistorical and I just wrote this wrong to begin with lol)
In any case, this is more accurate, and I think I'm also maybe
incidentally noticing that it's running faster, at least in my brief
before/after production testing? (There's *more* queries, like 100! But
many of them are *very* fast lookups, coming in at under 1ms—and also a
lot of them are dupes being served by Rails's request-scoped query
cache.)
I have some other changes planned too, but these are some easy ones. I
also turn back on this stuff in development, in hopes that my changes
can make these queries fast enough to not be a big deal anymore!
This is the second part of the previous change `efda6d74`, in which we
switch out the item search query conditions!
This was a two-parter to ease deployment: first deploy the change with
the migration, then *run* the migration (because it's an unusually slow
one), then deploy this change that actually uses it.
Another way to approach this would've been to deploy it all in one
commit, but not set it as `current` until we had run the migration.
That would have been a reasonable approach too!
This is the first part of a change to improve search performance, by
caching occupied zone IDs and supported body IDs onto the Item record
itself, instead of always doing joins with `SwfAsset`.
It's unfortunate, because part of the power of SQL is joins! But doing
joins with big tables, in ways that can't take advantage of indexes in
the same ways as we often want to, is… slow.
It's possible there's something I'm misunderstanding about SQL
optimization, and this _could_ be done with query optimization or
indexes instead of duplicating data like this? This complexity carries
the risk of data getting out of sync in unforeseen ways. But this is
what I know how to do, and it seems to be working, so! Okay!
There's some funny bugs we had here, like "Relic Elephante Jewellery"
and "Royal Girl Skeith Bodice" getting assigned "Ice", and
"Tyrannian Meerca Spear" being "Pea" lmao
I went and checked all the assignments now and they look good to me!
```ruby
Item.is_pb.order(:name).
map { |i| [i.pb_color&.human_name, i.name] }
```
We call it enough times on this page, and it *does* have a SQL query,
that I want to cache it! (Also I want to make it fewer species queries
if I can tbh…)
Adapting what the Impress 2020 UI does, but in Ruby instead!
I feel like this is case is really starting to show the power of doing
this stuff in Rails instead of via an API… we can *really* take
advantage of our models and our handy idioms at all points. This is
just so much less *code* than this feature takes in Node + GraphQL +
React.
We used to use this to determine what color to show by default on the
item page preview for, like, Maraquan-specific items. Now, we infer it
from our actual customization data, rather than these heuristics!
There's still a database field for `Item#manual_special_color_id`. We
can still read and write this from the support UI, and Impress 2020
still slightly uses it from the homepage, so I'm not removing from the
database right now.
I'm about to reimplement the more-robust version of what this used to
be: how the item page used to say "sometimes" after certain zones in
the occupied list.
Now, we're going to do parity with 2020, and list the actual species!
I like that this takes away the weird `#sometimes` method on the `Zone`
class, which was always an odd hack for just this small thing.
Also adapted from the Impress 2020 logic!
Note that I refactored `compatible_pet_type` to a series of scopes on
`PetType`. I think this is a simpler, clearer, and more flexible API!
This is a cute thing that I think sets us up for other stuff down the
line: move more of the outfit appearance logic into the `Outfit` class!
Now, we set up the item page with a temporary instance of `Outfit`,
then ask for its `visible_layers`.
Still missing restricted-zones logic and such, that's next!
Just stripping out the big React component, and having Rails output it!
There's a lot of work rn in extracting the Impress 2020 dependency from
the `wardrobe-2020` React app, and I'm just curious to see if we can
simplify it at all by pulling this stuff *way* back to basics, and
deleting the item page part of `wardrobe-2020` altogether.
In this draft, we regress a lot of functionality: it just shows the
item on a Blue Acara, with no ability to change it! I'm gonna play with
putting more of that back in.
I also haven't actually removed any of the item page React code; I just
stopped calling it. That can be a cleanup for another time, once we're
confident in this experiment!
There's just starting to be a lot going on, so I pulled them out into
here!
I also considered a like, `Item::DyeworksStatus` class, and then you'd
go like, `item.dyeworks.buyable?`. But idk, I think it's nice that the
current API is simple for callers, and being able to do things like
`items.filter(&:dyeworks_buyable?)` is pretty darn convenient.
This solution lets us keep the increasing number of Dyeworks methods
from polluting the main `item.rb`, while still keeping the API
identical!
Silly mistake, right, we might not have a trade value listed! This is
relevant for the new Dyeworks items that just came out like a few hours
ago, which Owls doesn't have info for yet.
Previously, I added a Dyeworks section that was incorrect: the base
item being available in the NC Mall does *not* mean you can necessarily
dye it with a potion!
In this change, we lean on Owls to tell us more about Dyeworks status,
and only group items in this section that Owls has marked as "Permanent
Dyeworks".
We don't have support for limited-time Dyeworks items yet—I've sent out
a message asking the Owls team for more info on what they do for those
items!
I started writing this up, then sent a preview to a friend, and he was
like "oh cool, but also this is not correct?"
I didn't realize Dyeworks has limited-time support to be *able* to dye
certain items. Hey, glad we're writing this guide for people like me,
then! lol
I wonder if we can lean on Owls for this. It seems like they already
list "Permanent Dyeworks" for some items, I wonder if they say
something special for active limited-edition Dyeworks items!
In this change, instead of *always* inferring the Dyeworks base item
from the item name at runtime, we now have a database field that tracks
it, and auto-populates whenever an item *seems* to need a Dyeworks base
item but doesn't have one yet.
This will enable us to set the base item manually in cases where it
can't be inferred, and load Dyeworks base items for the Item Getting
Guide in one query with `includes(:dyeworks_base_item)`.
This migration does a bit more of the fix-em-up scripting work *in* the
migration itself than I usually do, mainly because there's so much in
this one that I think being extra-explicit is useful. We make sure to
do it gracefully though!
This works for most of the current 1,094 Dyeworks items! But there are
a few exceptions, for cases where the base item name is not quite the
same (e.g. the Dyeworks version is more concise). Maybe we'll add a
database field to override this?

I noticed in the app that these queries were slowwww! I was able to
track it down to a bad query plan, as we explain in the comment.
I searched online for "mysql query performance filter on one join table
sort by another", and was surprised to find this answer suggest a
subquery, which I've often been told to expect to be slower compared to
joins? But it certainly worked in this case!

Now, for colors like Mutant or Magma where there's no paint brush
image to show, we use a sample pet image instead, to help it have equal
visual weight and clarity as the cases with the paint brushes.
We do some cleverness in here to make sure to always show the relevant
species, if possible!
NC prices, some CSS, and also a new application-level helper that adds
a feature I've long wanted and been working around for Turbo: the
ability to specific that a stylesheet is specific to the current page,
and should be unloaded when removed!
I use this to write `sources.sass` without the usual
`body.items-sources` scoping that we've historically used to control
what pages a stylesheet applies to. (In the long past, this was because
a lot of stylesheets were—and still are–routed through the
`application.sass` stylesheet! But even for more recent standalone page
stylesheets, I've done the scoping, to avoid issues with styles leaking
beyond the page they're meant for when Turbo does a navigation.)
This'll affect the recommended acquisition method by a lot!
NC Mall info like current price isn't surfaced anywhere else in the app
right now. It'd probably be good to add to the item page, and maybe
some other places too!
