We're now caching `predicted_fully_modeled?` on the database record, so
we can query by it in the database!
I'm moving on from the model I did in Impress 2020, of writing really
big fancy single-source-of-truth queries based on the assets themselves.
I see the merit of that in terms of theoretical reliability, but in
practice I think it will be *more* reliable to have one *in-code*
definition of modeling status (which we need anyway for generating the
homepage modeling requests), and just save that in a queryable way.
In our tests, I discovered an unexpected behavior where calling
`item.swf_assets << swf_asset` wasn't updating computed fields
correctly.
This isn't something we actually do in-app, I think the modeling system
happened to trigger the callbacks in a way that still worked fine?
But I think this is a good idea for reliability, since caching is such
a notoriously difficult thing to get right anyway! And it makes our
tests simpler and clearer.
Specifically, `compatible_body_ids` references `swf_assets`, which, I'm
kinda surprised, *doesn't* include the newly-added asset yet when the
`ParentSwfAssetRelationship.after_save` hook runs while calling
`item.swf_assets << swf_asset`. Reloading it fixes this!
I'm grouping some shared behaviors to pull into the different cases, so
that we can check the behaviors of a fully-modeled item vs a
not-fully-modeled item in *all* of the relevant cases.
Specifically, I'm planning to add `is:modeled` search filters, and
creating pending placeholder tests for them!
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!
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!
