Rails Daily: The Case of the Silent No-Op
One contributor, user 55728, drove six separate fixes across Rails today, nearly all sharing a pattern: an option or argument gets accepted, forwarded, and then quietly ignored or mishandled instead of raising an error. Rounding out the day, MySQL's spatial column detection was corrected and Rails 8.1's schema versioning documentation and internals got a cleanup.

PR 58091 fixes SQLite3's `add_check_constraint`, which accepted `if_not_exists: true` but never declared it — the flag fell through to the general options hash and was silently ignored, so you'd hit an error you thought you'd opted out of. PR 58086 found the same shape of bug in…
Time handling got attention too. PR 58085 fixes `Time.at` losing sub-second precision when coercing a `DateTime`, because it converted through a float instead of an exact rational — wrong by up to half a microsecond, roughly half the time. PR 58092, still open, addresses `relative_time_in_words` comparing the wrong…
On the generator side, PR 58080 fixes `GeneratedAttribute#to_s` mangling the `null: false` modifier so regenerated attribute strings didn't parse the same way twice — a maintainability trap for anyone scripting model generation.
