Good morning, this is Rails Daily for May 2nd, 2026.
Jack Bowlin merged a small cleanup fixing typos in test descriptions across ActiveStorage and ActiveSupport. The pull request corrected "reqiure" to "require" and "explicity" to "explicitly" in test strings without changing functionality.
The more significant update came from a commit by merely, addressing a critical ActiveStorage bug. The team added explicit `as_json` methods to `ActiveStorage::Attached::One` and `Attached::Many` classes. Previously, these objects caused infinite recursion during JSON serialization when attachment columns shared…
Additional commits included Petrik improving MemCacheStore error handling by raising ArgumentError when created with Dalli::Client, aligning with existing deprecation removals. Jean Boussier also corrected a typo in the railties changelog.
What's next: Developers using ActiveStorage with custom JSON serialization should test their implementations with the new `as_json` behavior. Teams using MemCacheStore should verify their configuration doesn't pass Dalli::Client instances directly.
That's your Rails update for today.
