I built this API endpoint in anticipation of a change I never actually
made! I'll just remove it for now, leaning toward cleanuppery over
holding onto something I'm not sure about.
I'm gonna also use this for a task to try to warm up *all* the
manifests in the database! But to start, just a simple one, to prepare
the alt styles page quickly on first run. (This doesn't really matter
in production now that I've already visited the page once, but it helps
when resetting things in dev, and I think more it's about establishing
the pattern!)
Preparing to finally move wardrobe-2020's item search to use the main
app's API endpoints instead!
One blocker I forgot about here: Impress 2020 has actual support for
knowing an item's true appearance, like by reading the manifest and
stuff, that we haven't really ported over. I feel like maybe I should
pause and work on the changes to manifest-archiving that I'd been
planning anyway? I'll think about it.
Okay, so I still don't know why rendering is just so slow (though
migrating away from item translations did help!), but I can at least
cache entire closet lists as a basic measure.
That way, the first user to see the latest version of a closet list
will still need just as much time to load it… but *only* the ones that
have changed since last time (rather than always the full page), and
then subsequent users get to reuse it too!
Should help a lot for high-traffic lists, which incidentally are likely
to be the big ones belonging to highly active traders!
One big change we needed to make was to extract the `user-owns` and
`user-wants` classes (which we use for trade matches for *the user
viewing the list right now*) out of the cached HTML, and apply them
after with Javascript instead. I always dislike moving stuff to JS, but
the wins here seem. truly very very good, all things considered!
I think this was to explain why `order` wasn't part of this query, and
we probably used to sort in the controller? But now the item search
module takes care of all that, this is just confusing to say now imo!
Mostly this is just me testing out what it would look like to
modularize the app more… I've noticed that some concerns, like
fundraising, are just not relevant to most of the app, and being able
to lock them away inside subfolders feels like it'll help tidy up
long folder lists.
Notably, I haven't touched the models case yet, because I worry that
might be a bit more complex, whereas everything else seems pretty
well-isolated? We'll try it out!
Okay right, the wardrobe-2020 app treats `state` as a bit of an
override thing, and `pose` is the main canonical field for how a pet
looks. We were missing a few pieces here:
1. After loading a pet, we weren't including the `pose` field in the
initial query string for the wardrobe URL, but we _were_ including
the `state` field, so the outfit would get set up with a conflicting
pet state ID vs pose.
2. When saving an outfit, we weren't taking the `state` field into
account at all. This could cause the saved outfit to not quite match
how it actually looked in-app, because the default pet state for
that species/color/pose trio could be different; and regardless, the
outfit state would come back with `appearanceId` set to `null`,
which wouldn't match the local outfit state, which would trigger an
infinite loop.
Here, we complete the round-trip of the `state` field, from pet loading
to outfit saving to the outfit data that comes back after saving!
Yay it works(*)! But two major missing pieces:
- Outfit saving doesn't persist it at all
- Item compatibility is unaffected: items will still appear in search
and in the preview, even when they don't fit anymore.
To help with space, I'm just showing the word "Nostalgic" (or "???" if
it's from a series we don't recognize, this is hardcoded by ID), and
trusting that from context it will be obvious that it's the "Nostalgic
Faerie" case or whatever. (Moreover, in both the button and the select
we're omitting the species name, by similar reasoning!)
Note that this _still_ doesn't actually apply the style to the outfit
whatsoever; this is all just local state as we're continuing to play
with UI concepts. Actually applying it is probably next though! (Though
there's a couple more UI things I want to do, like some affordances to
clarify that a Style is applied and that Expression changes won't work.)
It was a bit tricky to figure out the right API for this, since I'm
looking ahead to the possibility of splitting these across multiple
pages with more detail, like we do in DTI 2020.
What I like about this API is that the caller gets to apply, or not
apply, whatever scopes they want to the underlying hanger set (like
`includes` or `order`), without violating the usual syntax by e.g.
passing it as a parameter to a method.
Oh yeah, a long-standing limitation. Good thing we're better at stuff
now!
This is also probably the real cause of the weird number of slight
discrepancies between main DTI and DTI 2020 when I eyeballed stuff lol
oh, well, that and the missing default-lists. A bit messy!
Ahh I see, the way we got away with not having a `trading` scope before
was a weird metaprogramming `{owned/wanted}_trading` situation. Okay,
let's trash that in favor of our new stuff! And that helps us bulk the
queries too which is nice.
Building toward replacing more of the 2020 data sources! I think this is
an endpoint that benefits from bulk loading, esp with the way the item
page previews work. I also like taking the concept of "canonical" out of
the GQL interface, and instead just loading for each of the 50 species
and letting the client decide. (And then it can fast-swap between them!)
Just moving more stuff over! I modernized Item's `as_json` method while
I was here. (Note that I removed the NC/own/want fields, because I
think the only other place this method is still called from is the
quick-add feature on the closet lists page, and I think it doesn't use
these fields to do anything: updating the page is basically a full-page
reload, done sneakily.)
Preparing a better endpoint for wardrobe-2020 to use! I deleted the
now-unused swf_assets#index endpoint, and replaced it with an
"appearances" concept that isn't exactly reflected in the database
models but is a _lot_ easier for clients to work with imo.
Note that this was a big part of the motivation for the recent
`manifest_url` work—in this draft, I'm probably gonna have the client
request the manifest, rather than use impress-2020's trick of caching
it in the database! There's a bit of a perf penalty, but I think that's
a simpler starting point, and I have a hunch I'll be able to make up
the perf difference once we have the impress-media-server managing more
of these responsibilities.
This hasn't worked for a while, and I don't know an API off the top of
my head to drop in for it. Let's just delete it for now, and revisit it
later if we want to!
Dang, I'm really wishing I'd opened this sooner cuz I didn't realize it
would be THIS easy!!
The bug was that the `t` method started taking Ruby keyword params
instead of a hash object for `options`, so the syntax changed.
Womp womp!
A really really simple change! It works on the item page, the item
index page, item search, the homepage, and the item lists page.
The main reason I avoided this for so long (even before modernizing the
Rails app) was that the ElasticSearch stuff felt like it made it messy?
But now it's pretty simple, and it works in search already cuz I did
that when I implemented item search, so, nice!
This came in a few parts!
1. Add meta tags to let us know we're logged in.
2. Install React Query, which has the data-loading sensibilities I like
about Apollo without the GraphQL that has honestly been a drag.
3. Replace the outfit-loading and outfit-saving calls with API calls to
the main app.
4. Update the main app's API calls to use our more flexible data
constructs like "pose".
Would've loved to do this more incrementally, but it's hard to! You
can't split out outfit-loading and outfit-saving, or auth from any of
that, or the state gets all out-of-sorts.
Still, this is a good nugget we've pulled out all-in-all, and one that
people have been asking for! Can maybe look to logged-in item search
soon too, for own/want data?
I used the new profiler tools on this page, and noticed a lot of
allocations in the Globalize library, which we use for translating
database records. I realized that we were loading all of the fields of
not just all of the items on the page, but all of their translation
records in all locales! We used to scrape data for lots of languages, so
that can be quite a lot!
Unfortunately, Rails's `includes` method to efficiently preload related
records always loads all fields, and simply can't be overridden.
So, in this change we write manual preloading code, to identify the
records we need, load them in big bulk queries, and assign them back to
the appropriate associations. Basically just what `includes` does, but
written out a bit more, to give us the chance to specify SELECT and
WHERE clauses!
It shows up in development always, and if you're logged in as Me
Specifically in production!
I'm using this to poke at memory usage for pages that seem suspicious.
I don't know why our app reliably grows so large in RAM, but my hunch is
that maybe there are some pages that just use a truly large amount to
begin with - and I've learned Ruby doesn't release memory back after
it's GC'd, it just grows the process and keeps the free space to itself
in its own heap!
So I'm just eyeing pages that I know *can* have a lot going on, and
seeing what I find!
