[Ruby on Rails (RoR)] asdf install Ruby 3.x and Rails 7.0 on macOS
asdf, Ruby 3.x and Rails 7.0
Rails 7.0 has been years in the conceptual making. It’s the fulfillment of a vision to present a truly full-stack approach to web development that tackles both the front- and back-end challenges with equal vigor. An omakase menu that includes everything from the aperitif to the dessert.
And here are some of the many other new features and improvements:
At-Work Encryption With Active Record
Extracted from HEY, we’ve added encrypted attributes to Active Record, so your application can offer at-work encryption in addition to the traditional at-rest and in-transit coverage.
Trace Query Origins With Marginalia-Style Tagging
Almost a decade ago, Marginalia was extracted from Basecamp to trace query origins with SQL comment tagging. Now this external gem has been upstreamed into Active Record as QueryLogs.
Asynchronous Query Loading
When you have a controller action that needs to load two unrelated queries, you can now do it concurrently through Relation#load_async. If you have three complex queries that each take 100ms, you’d have to spend 300ms executing them one by one before. Now you can run them in parallel, spending only a total of 100ms on the set.
Autoloading in Rails is one of those magical quality of life realities that it’s easy to just take for granted. The trusty old const_missing approach which came with a range of quirks and missing features has finally been replaced exclusively with the Zeitwerk code loader. There are a few upgrade gotchas to be aware of, especially for older applications, but with this upgrade guide you should be on your way in no time
A Few Other Highlights
***Spring` is no longer on by default, as faster computers have made it less relevant on anything but the largest applications.
ActionController::Live#send_streammakes it easy to stream files that are being generated on-the-fly in controller actions.
Parallelized testing will now compare your CPU core count to your test count and scale the parallelization accordingly.
Active Storage now uses the faster and more secure
libvipsas its default variant processor.
