1. ArticleRead.user_id 改 Integer(users.id 是 Integer,不是 BigInteger) alembic 0007 同样改 Integer 2. ArticleDetail.vue toggleRead 重复 catch 块导致 build 失败 (edit 时新加的 catch 跟 toggleStar 残留的 catch 撞了)

"""文章已读记录(per-user)。
|
|
|
|
设计:
|
|
- 复合主键 (user_id, article_id) — 天然防重复,标记已读是幂等的
|
|
- read_at 默认 now(),用于排序(最近已读在前)
|
|
- 索引: (user_id, read_at DESC) — 用户查自己最近已读用
|
|
(article_id) — 反向查"谁读过这文章"(暂不用,留扩展)
|
|
|
|
注意:
|
|
- 删文章时 ondelete=CASCADE 自动清掉已读记录
|
|
- 这是和 bookmarks 并列的"用户行为"表
|
|
- user_id 是 Integer(users.id 是 Integer),article_id 是 BigInteger(articles.id 是 BigInteger)
