Milestone 328's acceptance test compared a database built by the real
0001..0087 chain against one built from the models, and found ~130
places where they disagree. This closes them.
Almost all were the MODEL being wrong, so almost all of this is model
edits with no DDL — the database already had these things, nothing in it
changes, and no deploy is needed for this part:
* 92 columns gained server_default. The models carried Python-side
`default=` only, so the ORM filled the value and the column had no
database default. Anything inserting outside the ORM behaved
differently from production.
* Eleven indexes that existed only in migrations are now declared:
the three backup_run reporting indexes, the two date-ordered
image_record browse indexes, import_task and presentation_review,
and the three task_run history indexes. All use text() for their DESC
ordering and postgresql_where for the partial one.
* Two UNIQUE indexes that autogenerate silently proposed DROPPING,
because neither is expressible as a UniqueConstraint:
uq_tag_name_kind_fandom — an EXPRESSION index over
(name, kind, COALESCE(fandom_id, 0))
uq_post_artist_external_id_null_source — PARTIAL, WHERE source_id
IS NULL
post.py already had a comment describing the second one. The comment
was right; nothing declared it.
* The two external_link enum CHECKs (host, status) — rule 36 territory,
and absent from the model entirely.
* Two indexes were named explicitly. A bare index=True generated
ix_tag_alias_canonical_tag_id where the database has
ix_tag_alias_canonical, so autogenerate proposed a drop+create of an
index that was already there under another name. Same for
tag_suggestion_rejection.
Only ONE thing needed DDL, as 0088: tag.fandom_id is declared
index=True but no migration ever created that index.
Deliberately NOT here: image_record.sha256. The model says unique=True;
0001 created a plain index. Duplicates are possible today and the ORM
believes otherwise. The fix depends on whether duplicates already exist
— if they do, that is a dedupe decision, not a constraint — so it waits
on an answer about live data.
The real severity of #3275 is not the squash. It is that --autogenerate
has been unsafe on this project: run against the old models it would
have proposed dropping eleven indexes and two uniqueness guarantees.
