Hey there!
Newsletter team is back to your inbox delivering all latest good commits and pull requests from Rails. Hopefully you have your favorite drink right there with you to make this quick reading ever better.
Featured
This week’s Rails contributors
Over 25 people contributed to Rails this week alone. Perhaps by our next newsletter your name could be on that list too!
Improved
Efficient lookup for many models in Global ID
Latest version of Global ID 0.3.2 brings better look up for models. You can pass an array of ids to locate_many
to fetch records only once per model. Check out the juicy comments of Core Team members figuring out their own API.
Partial names don’t have to be valid Ruby identifiers
Rails master can render partial names like _the-friday-party.html.erb
just fine now as well. If you are feeling extra adventurous, you might even try naming your partials with emojis!
perform_enqueued_jobs
can filter jobs by type
By passing a only
option you are able to test only those particular jobs while any other inside the block won’t be performed. Checkout the changelog entry introduced for a crystal clear example usage.
Fixed
Child record validation respects validate: false
on parents
Took a few years but this is fixed! Persisting child records will respect the current validation state of the parent record. Also good to see how the team is worrying about performance penalties for fixes in ActiveRecord core logic.
Removed
Dropping xhr
helper to simplify AC::TestCase
You will need to update your test suites in case they use either xhr
or xml_http_request
test helpers. Instead switch to the regular get
and pass the keyword argument xhr: true
Farewell Rails built in documentation tasks
Now comes a goodbye to a few friends most of us never knew we had: the documentation rake tasks. The three siblings doc:app
, doc:rails
and little doc:guides
joins local documentation in a better place - online. Our thoughts are with the remaining rake tasks. Rest In Protocols.
One More Thing™
Eileen M. Uchitelle is a Rails Committer
Eileen has been doing awesome work on Active Record related to performance refactoring and bug fixes besides mentoring some students in the Facebook Open Academy program.
