A security release, bugfixes and more!

Hey, this is Greg, bringing you the latest news about Ruby on Rails!

Rails has been released!

Rails has been released! It is a security release and addresses a possible XSS attack vector in Actionable Exceptions.
You can read more about the issue here and check the commit with the fix here.

Optimize ActiveRecord::Relation#include? on an unloaded relation

This PR introduces an exists? call instead of loading the entire relation into memory and that makes it better performing.

Fix ActiveRecord::Relation#include? in case where offset is provided

A follow-up PR for the above improvement, because the original solution broke includes? when an offset was provided, but this change covers that case and falls back to loading the relation in case an offset is provided.

Support passing record to uniqueness validator’s :conditions option

With this change, it is possible to build conditions based on the record’s attributes for a uniqueness validation.

Allow for only no-store in cache-control header

This PR allows one to set the default Cache-Control header to reflect the simple no-store directive exclusively and all other cache directives are dropped when that’s set.

Destroying associations asynchronously, interval datatype and more

Hi, Wojtek from this side. We are coming back with newsletter! Here are the changes in Ruby on Rails codebase from the last week.

Destroy associations via background job

Destroying associated records can now be done in background job by setting dependent: :destroy_async option.

Support for PostgreSQL interval datatype

Add support for PostgreSQL interval data type with conversion to ActiveSupport::Duration when loading records from database and serialization to ISO 8601 formatted duration string on save.

Per environment Active Storage config files

Active Storage configuration files for specific environment like config/storage/production.yml will take precedence over config/storage.yml.
It should ease complex configuration scenarios which may arise when configuring services per attachment.

Base class for Active Storage, Action Text and Action Mailbox

Permit applications to hack in custom databases for Active Storage, Action Text and Action Mailbox models by extracting base Active Record class.

17 people contributed to Rails since the last week. Check out the detailed list of all changes. Until next week!

May of WTFs, RailsConf and more

This is Greg and Wojtek bringing you the latest news about Rails in these crazy times.

A May of WTFs

Have you ever lost time on some strange Rails issue? Would you like to make it go away, so the others won’t do the same? It is an initiative running this month to improve Rails, especially for the first time users. Check the details and help making Rails better!

RailsConf - Couch Edition

This year RailsConf took place online. You can already watch all the videos. Take a look at the official announcement or jump straight to the playlist here.

Rails 6.0.3 has been released

This version fixes warnings when used with Ruby 2.7 altogether with many other framework bug fixes.

Instrument layout rendering

With this addition it is possible to listen on more specific action view layout rendering instrumentation.

Inspect time attributes with subsec


#<Knot id: 1, created_at: "2016-05-05 01:29:47">


#<Knot id: 1, created_at: "2016-05-05 01:29:47.116928000">

Test file patterns configurable via Environment variables

It is now possible to control which test files to execute by setting DEFAULT_TEST or DEFAULT_TEST_EXCLUDE environment variables.

Fix aggregate functions to return numeric value consistently even on custom attribute type

Count and average always returns a numeric value, but sum, maximum, and minimum did not always return a numeric value if aggregated on a custom attribute type.

Deprecate passing a column to type_cast

The type information for type casting is entirely separated to type object, so if anyone does passing a column to type_cast in Rails 6, they are likely doing something wrong. See the PR for a more thorough explanation.

Deprecate allowed_index_name_length and in_clause_length in DatabaseLimits

In the past, the SQLite3 adapter relied on allowed_index_name_length, but it is no longer needed so it got deprecated. in_clause_length also got deprecated in https://github.com/rails/rails/pull/39057.

38 people contributed since our last issue. You can check the full list of changes. Keep safe out there!

A May of WTFs: Let's hear about all the potholes, roadblocks, and roundabouts!

The bar for reporting a bug to the Rails project can be pretty steep. You’re expected to carefully diagnose the problem, preferably propose a solution, include detailed reproduction steps, and all the other homework that makes it possible for a project like Rails to deal with hundreds if not thousands of reports on a yearly basis.

While this is a reasonable process for collecting actionable reports that a small group of contributors can reasonably triage, it’s not a great process at all for learning about all the the potholes, the roadblocks, and the roundabouts that make your journey that much more uncomfortable or take longer. That stuff just gets swallowed up by the sinkhole of grievances (have I exhausted the metaphor yet?! 😂).

So when Avdi took to air some of those grievances on Twitter, the natural thing happened that always happens when you feel your work is attacked: The core contributor group got defensive! That’s a mischaracterization! Where are the completed bug reports!? You know the drill, if you’ve ever worked on something, poured your heart into it, and then seen it criticized online. There’s that immediate, knee-jerk reaction of a sting. But it doesn’t have to sting.

“Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom” – Victor Frankl

We’re now choosing that response to be something different than the typical response to a perceived slight. Our response will be that of growth, and its essence is that Avdi’s frustrations are broad frustrations, they’re valid frustrations. They’re perhaps not yet in an actionable form, like we’re used to with perfectly described bug reports, but we can turn them into that! Together!

And even more, we can accept that Avdi’s frustrations are not anywhere near broad enough to cover all the frustrations. So we can ask for more! In a structured way, under a new paradigm of inquiry, and we can make Ruby on Rails better together. That sounds pretty good, no?

So that’s what we’re doing! We started a small group to involve Avdi, Betsy, and others who’ve expressed grievances or interest in those grievances to work together. And the first project to come out of this group is what we’re calling A May of WTFs. It’s a new category on the Ruby on Rails discussion forum, and it’s going to be a safe space for those WTFs you weren’t going to turn into formal bug reports. It’s going to be timeboxed to the month of May. And it’s going to run under the championship of Betsy Haibel. So I’ll let her set the terms of engagement:

We all lose time to “Rails WTFs.” Something goes weird in our Rails process, and we spend four hours frantically reading Stack Overflow before it finally occurs to us to restart Spring. Or we make one silly typo and it causes the autoloader to lose track of an entirely different class.

It can be hard to write bug reports for a WTF. When it’s difficult to understand what triggered it an issue, or what fixed it, nailing down a good reproduction seems impossible. And who wants to go to that effort when they’ve just spent hours staring at byebug and cursing computers?

This May, the Rails team is going to be tackling some of these WTFs – which means we need you to tell us about them! Send us your strangest Rails 6 stories, even if you don’t really understand what triggered them or remember how you fixed it. Provide as much detail as you can – but don’t worry over what you can’t. We’ll be looking through all of this for patterns that will let us improve Rails (or at least its error messages) for everyone.

So please, come join us in a May of WTFs. Help Betsy, Avdi, and everyone else who’s interested in transforming the raw energy of frustrations into gleaming patches to documentation, error messages, or even APIs. We’ll take WTFs as input and produce 💖 as output.
