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.
Not using this on the item page preview yet, but we will!
I like this approach over e.g. a web component specifically for the
sandboxing: while I don't exactly *distrust* JS that we're loading from
Neopets.com, I don't like the idea of *any* part of the site that
executes arbitrary JS unsafely at runtime, even if we theoretically
trust where it theoretically came from. I don't want any failure
upstream to have effects on us!
I copied basically all of the JS from a related project
`impress-media-server` that I had spun up at one point, to investigate
similar embed techniques. Easy peasy drop-in-squeezy!
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!
Oh huh, TIL in Ruby `^` *always* means "start of line", whereas in many
languages' regular expression engines it means "start of string" unless
you enable a special multiline flag for the pattern.
I've fixed this in a number of expressions now!
I'm noticing this in the context of doing some security training work
where this the cause of a sample vulnerability, but, looking at our own
case, I don't think there was anything *abusable* here? But this is
just more correct, so let's be more correct!
Huh, I thought I'd tried some invalid dates and they gave me
*surprising* output instead of raising an error. Well, maybe it can do
both, depending on exactly the nature of the unexpected input?
In any case, I found that a bad month name like "UwU" raised an error.
So, let's catch it if so!
Oh right, if I assume "date in the past means it's for next year", then
that means that, when the date *does pass*, we won't realize it!
e.g. if Owls says "Dyeable Thru July 15", then on July 14 we'll parse
that as July 15, 2024; but on July 16 we'll parse it as July 16, 2025,
and so we'll think it's *still* dyeable. Under this logic, it's
actually impossible for a limited Dyeworks date to *ever* be in the
past, I think!
I think 3 months is a good compromise: it gives Owls plenty of time to
update, but allows for events that could last as long as 9 months into
the future, if I'm doing my math right.
Ahh, I started a tabs-y file (as I default to these days), but copied
code from a spaces-y file, and didn't notice. (My laptop editor isn't
configured to flag this for me, oops!)
Fixed!
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?

This is less likely than the newly-released color case for PB items,
but I figure let's be resilient anyway, especially since it's so easy
to—and also I figure this is less likely to be triggered by an *actual*
new species, and more likely to be triggered by a surprise in an item's
naming conventions.
But yeah, if `Item#pb_species` returns `nil` upstream, it'll be passed
to `Color#example_pet_type`, which will crash trying to read its ID. So
in this change, we update `Color#example_pet_type` to accept a `nil`
value, and fall back to the first Species (Acara) in that case.
This means that, if you e.g. take the Mutant Aisha Collar and delete
the word "Aisha" from the name, then load it in the Item Getting Guide,
you'll see a thumbnail of a Mutant Acara. Good enough!
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!

I think the Rails query cache handled these anyway? But `SwfAsset` has
a `before_save` hook that checks its zone's info, and
`SwfAsset.preload_manifests` saves all the assets, on the assumption
that saving is a no-op when the record didn't change anyway. And it
basically is!
But I figure that, now that I'm realizing hooks exist, simply not
attempting to save unchanged records is probably a better
representation of what we intend to do. So I'm fixing it like that!
Another potential fix would be to preload the zones for these assets,
but I think that confuses the intent too much; the method itself isn't
using the zones, it's just a weird incidental thing that a save hook
happens to use. (Would probably be better to refactor this old save
hook into a different situation altogether, but that's for another
time!)
This is a minor nbd change, I just noticed when playing around in the
console that, unlike most other errors for this model, the `body_id`
being required is _only_ enforced in the database schema, so it isn't
returned with the usual errors. Not a big deal! Just feels like this is
clearer to work with, and more correct to what we *intend*.
This is just a bit of future-proofing! We also add a default thumbnail
URL of the cute "Neopets Circle Background", for cases where the series
name isn't known yet.
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!
