Saluton! That’s Esperanto for “Hello!” 😜… Emmanuel Hayford here, let’s see what’s new in Rails as we gear up for Composite Primary Keys (CPKs) support.
But first, here’s a fine opportunity for junior Ruby on Rails developers: As part of preparations for the upcoming Rails World conference in Amsterdam, Netherlands this year, The Rails Foundation is presenting an opportunity to junior Ruby on Rails developers. Paired with a mentor, the goal is for the junior developer to build a website to host the event!
Support deleting records from associations for CPK This PR improves the behaviour around deleting records from associations in composite contexts. Previously, an ArgumentError would raise if one attempted to delete records from associations in composite contexts.
Ensure that ids_writer and ids_reader are working for CPK The latest update to ids_writer addresses an issue with handling composite primary keys. Previously, the writer was able to handle a CPK model associated with a non-CPK model without any errors. However, when it came to a CPK model associated with another CPK model, the writer produced incorrect IDs. This PR fixes the issue.
Support batching using composite primary keys Batching was previously limited to tables with simple primary keys, but it can now be used with tables that have composite primary keys.
This update is one that’s long due.
The guide on Sprockets was also outdated as it was written before Sprockets 4.0, which introduced the manifest.js file, and some of its parts were no longer relevant. Furthermore, the guide failed to mention several useful gems, including jsbundling-rails , cssbundling-rails , dartsass-rails , and tailwindcss-rails.
This PR aims to bring the guide up-to-date with the latest changes in Rails and highlight the best practices for managing assets.
