Rollback scope after a schema change I am defining a rollback policy for a Rails application (assume a current Rails 7.x line with PostgreSQL) and need to pin down exactly what rails db:rollback is allowed to promise. Our migrations are written with change where possible, but some use remove_column , change_column , and occasionally execute for data cleanup.
In Rails 7.x, Active Record provides standard offset-based pagination. However, as datasets grow to millions of records, the linear performance degradation of OFFSET becomes a primary driver of database latency, especially when multiple concurrent requests compete for connection pool resources. While keyset pagination (cursor-based) is a recognized alternati
Goal: Ensure that date/time fragments rendered by Rails view helpers display the correct offset after a Turbo Stream update when a user changes their preferred time zone. Constraint: Turbo Streams inserts server‑generated HTML without performing any additional client‑side time‑zone conversion, and its cache‑busting flags do not automatically invalidate cache
