George joins Rails Core and Action Mailbox introduced

Hello. This is Wojtek with a short list of news from Rails world.

George joins Rails Core

George Claghorn is now a member of the Rails core team. Welcome George!

Introducing Action Mailbox for Rails 6

Action Mailbox is the brand new framework coming to Rails 6 extracted from Basecamp.

Add ActiveRecord::Base.connected_to?

Another handy method added to support multiple databases.

Fix numericality equality validation on floats

By casting values to BigDecimal comparision on validation is now more precise.

19 people contributed to Rails last week making lot of improvements.
Until next time!

Introducing Action Mailbox for Rails 6

Action Mailbox is the second brand new framework coming to Rails 6 (the first was Action Text). It serves to route incoming emails to controller-like mailboxes for processing in Rails. It ships with ingresses for Amazon SES, Mailgun, Mandrill, and SendGrid. You can also handle inbound mails directly via the Postfix ingress.

The inbound emails are turned into InboundEmail records using Active Record and feature lifecycle tracking, storage of the original email on cloud storage via Active Storage, and responsible data handling with on-by-default incineration. These inbound emails are routed asynchronously using Active Job to one or several dedicated mailboxes, which are capable of interacting directly with the rest of your domain model.

The framework was, like Action Text and Active Storage, extracted from Basecamp 3. We’ve been using a related approach to route everything from forwarded emails to email replies to messages and discussions. After extracting the ideas into Action Mailbox, we reintegrated the framework into Basecamp, and we’ve been running the code we’re sharing today for over a month in production.

Yes, Rails already had an anemic way of receiving emails using Action Mailer, but it was poorly flushed out, lacked cohesion with the task of sending emails, and offered no help on integrating with popular inbound email processing platforms. Action Mailbox supersedes the receiving part of Action Mailer, which will be deprecated in due course.

Rails 6 is getting closer, but it’s still a ways off – we’re hoping to start the beta process in early 2019. Action Mailbox is already in pretty decent shape, though, and you can even use it with Rails 5.2 applications, if you fancy dancing on the wild side. Just be prepared for things changing as we work our way through community review and towards merging it into rails/rails.

The Action Mailbox framework is based off ideas hatched by Jeremy Daer, and this particular implementation was done as a collaboration between yours truly and George Claghorn.

As part of the introduction of Action Mailbox, I plan to record a video showing off the basics in the near future. But the code is ready and somewhat documented for anyone to dive into already. So why sit on a good thing!

Between Action Text and Action Mailbox, Rails 6 is already shaping up to be one of the biggest releases in the history of the framework. And we’re not even done yet! Our plan is tentatively to have a release candidate version ready for RailsConf 2019 in Minneapolis. Please help us make that promise a reality by trying out Action Mailbox!

New Rails version, early new Ruby version fixes, and more!

Hello, hello! This is Tim here bringing you all the latest right from the Rails Edge.

In the northern hemisphere, daylight is getting scarce, driving certain folks in the Pacific Northwest to drastic measures. But the holiday season is upon us! We got an early pressie in the form of a new Rails release this week. Ans we can all look forward to Ruby release day!

On with the show….

Rails 5.2.2 has been released!

This week saw the release of a new patch version of Rails! Too numerous to list here, check out the official blog post for the full changelog.

This Week’s Contributors

This week 23 people gave back to Rails. For 7 of these folks it was their first time contributing! If you’d like to see yourself in a future edition of this newsletter, or alternatively just want to give back in a purely altruistic gesture, a great place to start can be checking out the list of open issues.

Ruby 2.6.0 fixes

As you may know, the release of Ruby 2.6.0 is right around the corner! We are very grateful to the folks who are already testing Rails on the release candidates and submitting patches ahead of time.

Non-primary mouse button clicks no longer trigger click events

This PR addresses an issue where certain browsers will fire a click event for non-primary mouse button clicks where others will not. They will all now behave uniformly thanks to this fix!

Unpermitted params log message now colorized

More colorized log messages for improved readability!

#delete_all on collection proxy returns count

This makes #delete_all behave uniformly across relations and collection proxies by returning the count of affected rows.

Test helpers docs added to guides

This PR documents some good practices for breaking test helpers out into separate files. Check it out!

ActiveJob::Base#enqueue to return false on failure

This makes the enqueue mechanism more consistent with the ActiveSupport::Callbacks design where if the callback chain is halted, it will return false. You can now use this feedback to determine if your job was in fact enqueued. Hurrah!

As always, there were way too many things to cover in full this week, but you can read about them all here. That’s all folks!

Safety checks to prevent database writes, cache performance boost and more

Cheers for the first day of December! This is Kir bringing you the latest news from the Rails world.

Use raw time string from DB to generate ActiveRecord#cache_version

The PR skips unnecessary attribute casting when generating cache version, which gives a great performance boost for apps that rely on caching.

Add ability to block writes to a database

A brand new while_preventing_writes method on Active Record connection allows you to add safety checks for code that’s not supposed to write to a database.

Bump the minimum version of PostgreSQL to 9.3

PostgreSQL 9.1 and 9.2 have been declared EOL more than a year ago.

Parallel tests on Windows, query cache with multiple databases and more!

Hello fellow Rubyists. This is Greg bringing you the latest updates from Rails.

Fix parallel tests on Windows

This pull request fixes an issue with running tests in parallel on Windows.

Allow using queue prefix with a default queue name

In Active Job, now if you define a queue_name_prefix it will be applied to the queue name set by default_queue_name as well.

Fix query cache for multiple connections

Active Records query cache now supports multiple database connections.

30 peoplecontributed to Rails last week. If you want to be part of that, check out the issues list. Until next time.

More multi database goodies and decaffeinated Rails

Hello fellow Rubyists. This is Wojtek bringing you the latest updates from Rails.

Note about CVE gems version bumps

Usually it is enough to update vulnerable gem within the application without a need to force it in the Rails codebase.

Multi database support for schema cache dump & clear

More goodies coming for multiple databases.

Add if_not_exists option to create_table

It is now possible to silently skip adding a table if it already exists during a migration.

Add support for unlogged PostgreSQL tables

If you ever wanted to create unlogged tables, now you can.

Convert CoffeeScript to JavaScript

So Rails is having fewer sips of coffee these days and of course never indulged in those dark blends of Java 😄.

37 people contributed to Rails within latest two weeks. Check out the full list of changes.

Special wishes to all RubyConf attendees ❤️. Until next time.
