Ohh ok, without this change all of our `scope`s were just immediately evaluating the argument and fetching _all_ such matching records immediately, instead of waiting to actually be called. This led to bugs like `pet_type.as_json` returning ALL pet states in the whole db, because the `PetState.emotion_order` scope was being treated as a single predefined query, rather than a query fragment to merge into the current context.
This also explains what happened in 724ed83: that's why things before the scope in the query were being ignored.
Ooh, this one was nasty, and only one symptom ever got noticed:
1. Pick "Occupies: Collar" in Advanced Search.
You get the text query "occupies:necklace".
2. And, if you try to do "occupies:collar" even in text-based search,
you *also* get the results from "occupies:necklace" mixed in with
the correct results.
The trick is that, in Spanish, zone 24 (necklace) is named "collar",
as is zone 27 (collar). Not sure what to do for Spanish, but this
issue also leaked into English: we really don't want English to return
results for Spanish-named zones.
This is a tricky problem, though, because it'd be nice for es users
to be able to type "occupies:hat". I think we'll have to do the quick
fix for now, though, and just only interpret the query in the current
locale.
We were joining to the translations table to sort records
alphabetically, but then it sorted by *all* of the translations in
some strange way. Now use with_translations to restrict the join
to the current locale.
