Association keys resolved once per class pair, Ractor proxy moves state to the main Ractor
By RepoJournal · Filed · About Rails · Composed from the cited sources · methodology
Active Record's association key handling collapses into a single Route object per concrete owner and target class pair, while the Ractor proxy adapter stops managing its own connection from the worker side.
AssociationRoute: consolidate how association keys are read and written rails/rails
Association keys are now resolved once for each pair of concrete owner and target classes as a Route, and queries, in-memory matching, and writes all run through it. Matthew Draper notes the refactor surfaced edge-case bugs (59073, 59074, 59075, 59076, 59079) plus others fixed incidentally "just because everything's going through the same implementation."
Keep Ractor-proxied connection state on the main Ractor rails/rails
The Ractor proxy adapter used to force an eager `connect!` at checkout and hand-crank verification and reconnects from the worker side; the main-side connection now tracks the worker's transactions and manages itself. The old approach could restore a transaction that had already been written to, losing that write.
Resolve association reads through routes rails/rails
Reads now resolve through the Route too, so keys, aliases, and polymorphic names come from the models involved rather than from the association declaration. Anything depending on declaration-time key resolution should be re-tested against this.
Run Active Record sqlite3_ractor test profile when available rails/buildkite-config
Buildkite now runs Active Record's sqlite3_ractor profile when the Rails version provides it, enabling tests with ractor proxy connection handling backed by sqlite3. The merge gates that profile to Rails 8.2a and newer.
