* Add search[order]=post_count param to /wiki_pages.
* Make autocomplete do a prefix match ordered by post count, so that it
works the same way that tag autocomplete does elsewhere.
* Add search[order]=post_count param to /artists.
* Make autocomplete do a prefix match ordered by post count, so that it
works the same way that tag autocomplete does elsewhere.
* The /artists page issued a `SELECT count(*) FROM artists` because
.paginate was missing search_count.
* /artists.json had an N+1 problem on artist urls. This slowed down
autocomplete.
Rendering the updater name at post_versions/_listing.html:25 caused
this for each post version:
SELECT "users".* FROM "users" WHERE "users"."id" = $1 LIMIT 1
PostArchive#diff caused this for each post version:
SELECT "posts".* FROM "posts" WHERE "posts"."id" = $1 LIMIT 1
Fixes an N+1 queries problem in the /moderator/post/queue view by
prefetching disapprovals and uploaders.
Also the way disapproval messages were previously rendered triggered a bunch
of sql queries for each post:
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 [["post_id", 52]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND "post_disapprovals"."reason" = $2 [["post_id", 52], ["reason", "breaks_rules"]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND "post_disapprovals"."reason" = $2 [["post_id", 52], ["reason", "poor_quality"]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND "post_disapprovals"."reason" IN ('disinterest', 'legacy') [["post_id", 52]]
SELECT COUNT(*) FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND (message is not null and message <> '') [["post_id", 52]]
SELECT "post_disapprovals".* FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 AND (message is not null and message <> '') [["post_id", 52]]
This refactors to bring it down to one:
SELECT "post_disapprovals".* FROM "post_disapprovals" WHERE "post_disapprovals"."post_id" = $1 [["post_id", 52]]
