Rails angle on the Postgres generic-plan trap: where(status: "pending") is sent as status = $1 with the value bound, so a partial index on status = 'pending' is exactly what execution six can lose.

where("status = 'pending'") keeps the literal. Checked on Active Record 8.1.4. #rails

The latest update for #AppSignal includes "Devise for #Ruby on #Rails: Setup, Modules & Rails 8 Auth" and "Handling Exceptions in Grape for Ruby: rescue_from and error!".

One controller went from 39% to 60% covered once the Cypress runs counted. Nobody wrote a new test: the Rails server just runs outside SimpleCov's test lifecycle. go.fastruby.io/tpo #Rails #Testing
