This week in Rails

Sat, 02/28/2015 - 01:56

Another week went by and here we are again, this is Greg with the latest news from the Rails community.

Featured This Week's Contributors

36 amazing people helped to make Rails even better this week! Thanks everyone!

Interview with Carlos Antonio and Rafael França

Interview with Rails Core team members about early days of their Rails contribution, Rails team, Brazil Rails community, their day to day tools of choice and workflow, and how everyone can help out with Rails.

New Stuff Default belongs_to validation

belongs_to relations will now trigger a validation error by default if the association is not present. If you wish, you can turn this off with the optional: true option per association.

Move the validate! method to ActiveModel::Validations

validate! was part of Active Record, but with this commit you can use it on any Active Model object!

Allow limit option for MySQL bigint primary keys

From now on, you can set a limit for your bigint type primary keys in MySQL.

Improved Faster template partial caching

Collections automatically use a read_multi for partials starting with a cache call from now on, which makes them faster.

Fixed Fixed ActiveModel.model_name.to_json

Previously, calling User.model_name.to_json would result in an infinite recursion, because .model_name inherited .as_json from Object. This commit delegates as_json to the correct handler to fix that.

Fixed mysql's schema.rb dumper

MySQL doesn't have a boolean datatype, it uses a tinyint with a limit option, so if we dumped the schema from MySQL we couldn't load it to Postgres since limit is invalid for Postgres booleans. This patch fixes that by not adding the limit to schema.rb.

Deprecated skip_action_callback is deprecated

In future skip_before_action, skip_after_action and skip_around_action will raise an ArgumentError if the callback doesn't exist, so using skip_action_callback, which calls all three methods will probably fail, therefore it became deprecated.

One More Thing™ Richard Schneeman is a Rails Committer!

Please welcome our newest Rails Committer @schneems!

Wrapping up

That's all for This week in Rails. As always, there are more changes than we have room to cover here, but feel free to check them out yourself!

This week in Rails: http_cache_forever, AR::Base.suppress and more!

Fri, 02/20/2015 - 23:37

My Valentine’s Day letter to Ruby on Rails:

“Dear Rails, remember the first time we met?
You were just 1.2, and I was in an unhealthy relationship with Perl and PHP.

I saw you in the library and I immediately fell in love.
For seven years, you made my code more readable and my skills stronger.

You are the most beautiful framework and always will be.
I cannot wait to see you turn 5.0.” – Claudio

Featured This Week's Contributors

Apparently I'm not the only one in love with Ruby on Rails. 36 programmers contributed to Rails this week, 10 of them for the first time. Keep loving!

New Stuff Add http_cache_forever to ActionController

The new method is perfect to cache results that are meant to never expire, such as static pages.

Add ActiveRecord::Type.register

You can now reference with a symbol any database type that is specific to your adapter, such as:
ActiveRecord::Type.register(:money, MyMoneyType)

Add ActiveRecord::Base.suppress

Wrapping a block with suppress will prevent any save operation from hitting the database. Check the PR for a real-world example.

Improved Add :time option to ActiveRecord::Base.touch

You can now touch an ActiveRecord instance with a different time than the current time.

Removed Removed RecordTagHelper

The helpers div_for and content_tag_for will be gone in Rails 5. Grab the record_tag_helper gem if you still need them!

Removed ActiveModel::Errors getters/setters

If you ever used person.errors.get(:name) or person.errors[:name] to read an error message, you should now switch to person.errors.messages[:name]. add_on_empty and add_on_blank are gone too.

Update: you should be using person.errors[:name] after all! Use person.errors.add(:name, ...) to append.

That's all for This week in Rails. As always, there are more changes than we have room to cover here, but feel free to check them out yourself!

This week in Rails: Speedy Integration Tests, Enum Queries and more!

Sat, 02/14/2015 - 01:00

Dearest darling, reindeer-eyed reader

Hither summoned is Kasper, Duke of Friendly Ghosts, to bring forth thy worthy commits and Pull Requests of Rails as subscribed.

Thusly commences our journey on this Friday the 13th - Ok, I'm sick of writing like that.

Featured This Week's Contributors

A round of applause goes to this weeks contributors from all of us at this virtual news desk. We editors did a full on spit take when realizing a whopping 28 people contributed. Nothing seals that memory quite like the scalding coffee on our thighs.

Integration Tests Only 12% Slower than Controller Tests

You may have thought Speed was just a movie. But we're feeling it this week as our world got rocked with a refactoring bringing integrations' speed closer to functionals. Stay at the edge of your seats for the sequel.

Improved Make enums queryable by label

After an amazing refactoring job on Active Record internals that took many months, this change was easy. Enums can now be queried by their labels. Post.where(status: Post.statuses[:draft]) is out in favor of Post.where(status: :draft).

fresh_when and stale? accepts a collection

They say that stale? is everyone's best friend. It will be by you until you get to fresh_when. Even if you need help when a collection seems impassable. Look around, you dingus, your best friends are adaptable.

There's usage examples on the Pull Request.

find_in_batches got an end_at option

Sometimes you gotta know when the fun oughta stop. Sadly find_in_batches and find_each would keep going like the party animals they are. Or were, as both matured this week with a new end_at option. But they're still keeping it plenty rad in their parents basement if anybody asks.

One More Thing™ Kasper Timm Hansen is an issues team member

Kasper first impressed us when he shipped his 2013 Rails GSoC project in 2014. In his spare time he writes a newsletter called This Week in Rails. In fact he wrote this very issue. Aw shucks, I thought there was something familiar about me and I!

Wrapping up

This was a weird one, right? Hopefully of the glorious kind.

That's all for This week in Rails. As always, there are more changes than we have room to cover here, but feel free to check them out yourself!

This week in Rails: locate_many, emoji partials and more!

Sat, 02/07/2015 - 00:10

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.

This week in Rails: Relation#or, file fixtures, kwargs and more!

Sat, 01/31/2015 - 02:13

It is that time of the week again!

This is Greg, bringing you this week's interesting commits and pull requests from Rails.

Featured This week's Rails contributors

Let's start with a big thank you for all the people who helped this week to make Rails better!

New Stuff Added #or to ActiveRecord::Relation

A long waited feature is added to Active Record and from now on you can combine two Active Record relations with the or operator.

ActiveSupport::Testing::FileFixtures

With this addition to ActiveSupport::Testing there is no need to write custom helpers for testing features requiring a sample file (i.e. file uploads).

Use kwargs in the test's HTTP methods

Support for keyword arguments is added to the HTTP methods of the controller tests. An example of the new syntax:

post :create, params: { y: x }, format: :json Improved Improved performance of integration tests

delegate turned out to be a bottleneck at the URL generation in the integration tests. With this patch the integration tests of the applications should have a speedup.

Allow hyphenated names for plugins

From now on you can generate a Rails plugin with a hyphenated name (i.e. namespaced engines).

Deprecated *_via_redirect integration test methods are deprecated

The *_via_redirect methods are deprecated but do not fear, you can use follow_redirect! in your test suite for the same behaviour.

Fixed Fixed HTTP basic authentication nil issue

When request.authorization returned nil, Rails raised a NoMethodError, but this is fixed now.

AR::Relation#group accepts SQL reserved keywords

This patch allows you to group by SQL reserved keywords with the group method of Active Record.

One More Thing™ Arthur Nogueira Neves is a Rails Committer

Please welcome our newest Rails Committer!

This week in Rails: model error details, drop table if exists and more!

Sat, 01/24/2015 - 01:01

It's Friday! Gotta get down on This Week in Rails!

This is Claudio, rushing to get you the weekly updates on interesting commits and pull requests from Rails.

Featured This week's Rails contributors

25 contributors helped Rails become a better framework. Keep the patches coming, and Rails 5 will be ready before you know it.

New Stuff ActiveModel::Errors#details

Given a user without an email, user.errors.details will return {email: [{error: :blank}]}. In some cases, this is more useful than the message {email: ["can't be blank"]} provided by user.errors.messages.
There's a good usage example in this blog post.

:if_exists option for drop_table

Writing drop_table(:users, if_exists: true) in a migration ensures that the migration will run without exceptions, whether or not the "users" table exists.

ActionController::Renderer

The ActionController::Base#render method can now output a template anywhere, even outside of a controller!

ActiveRecord::Base#accessed_fields

Calling @users = User.all to list all users works, but you can get better performance by indicating the exact fields you intend to access, for instance with @users = User.select(:name, :email).

The new @users.accessed_fields method will give you the list of fields accessed from the model, so you can easily optimize your queries using .select rather than .all.

Improved Speed up ActionController::Renderer

Everyone loves a pull request that speeds up Rails, especially if the performance gain is documented and verifiable.
When in doubt, always use benchmark/ips to provide benchmark results for comparison.

Wrapping up

That's all for This week in Rails. As always, there are more changes than we have room to cover here, but feel free to check them out yourself!

This week in Rails: tokens migrations, method_source and more

Fri, 01/16/2015 - 22:30

Live from our servers, it's This Week in Rails!

As always we're your inside scoop of interesting commits, pull requests and more from Rails.

This is Kasper, and I'm ready to serve you this scoop. I tapped keys on the board in front of me to make words appear. It's quite the tapestry.

Let's get to it!

Featured This week's Rails contributors

33 contributors made this week happen. Pull Requests were merged, new friendships were made... I think I even heard someone say they saw a cat online. That's a rare sight, and part of what made this week special. Thanks everyone!

Tokens in migrations and model generators

As a follow up to last week's has_secure_token, both the migration and model generators can create token attributes.
rails g migration add_auth_token_to_users auth_token:token. rails g model user auth_token:token.
The model generator automatically adds has_secure_token :auth_token to your new model file.

New Stuff method_source added to the default Gemfile

On Rails 5 when you generate a new app, you'll find 'method_source' in your Gemfile. This gem extends the Method class with source and comment methods to aid your debugging. There's a good usage example in this comment.

Fixed Allow '1' or true for acceptance validation

Previously validates_acceptance_of would only accept '1' as a valid attribute value. Now you can assign true to an attribute and the validation will pass.

Time columns will be aware of application time zone

In Rails 5.1 your time columns will adhere to the time zone of your Rails application. To make the upgrade path smoother, the config.active_record.time_zone_aware_types option has been added. See the deprecation warning here for help.

One More Thing™ Validation callbacks tested with contexts

A feature you might not have heard about is validation contexts, which allow you to specify a context a callback should only be run for. Like this: before_validation callback, on: :create. The link shows a few tests being for this on before/after_validation. Here is a more advanced example.

This week in Rails: a new beginning

Sat, 01/10/2015 - 02:00

Happy New Year, everyone!

It was only less than a year ago when I sent the first issue of This week in Rails to a total of 14 recipients, discussing some of the latest and greatest additions to the Rails codebase.

43 weeks later, this little hobby project has evolved into a true community effort –- we have assembled an amazing team of editors and other volunteers (join us!), keeping 2000 subscribers in the loop and highlighting some key contributions to our beloved web framework every week.

I am incredibly excited to announce that starting this week, we will be cross- posting the content from the newsletter to the Riding Rails blog. With this, we hope to reach even more members of our wonderful community, increase transparency, involve more of you in the decision-making processes and maybe even inspire some future contributors!

I would like to thank my team at Brewhouse and Goodbits for supporting the project and getting it off the ground, as well as all the volunteers who helped along the way. Of course, huge thank you to all of the Rails contributors who did all the hard work! <3 <3 <3

Without further ado, here is the first 2015 issue of This week in Rails!

Welcome to This week in Rails, your weekly inside scoop of interesting commits, pull requests and more from Rails.

Hi there this is Washington again!

Hope you all had the most gorgeous holidays ever doing things you love the most. The newsletter team is back to work and you should receive your Rails weekly news as usual. Here are some of the latest and greatest improvements, fixes and releases during the break.

Featured Ruby 2.2.0 Released

YAY! December 25th saw another important Ruby release. See the blog post for all the goodies in this new version and keep in mind Rails 5 will target Ruby 2.2+ exclusively. As of this week, Rails' master branch will only work on Ruby 2.2 or above.

Rails 4.0.13 and 4.1.9 have been released!

4.0.13 is last planned release for the 4.0 release series, so you should migrate off it as soon as possible. From here on, the 4.1 (you can thank Rafael) and 4.2 release series will continue to receive regular bug fixes. Consult the maintenance policy for details.

This week's Rails Contributors

Apparently holidays is no excuse for going to the beach all day long and having drinks away from computers. Rails community kept working hard during the break to keep improving the framework we appreciate so much. Thank you all!

New Stuff Halting callback chains by throwing :abort

As of Rails 5 callback chains won't be halted by returning false. Instead you should explicitly throw :abort. This will help keep things consistent among all frameworks included in Rails and avoid accidental halting caused by unexpected false return values.

New date helper

Working with days and weeks just got a bit easier. Keep in mind these new helpers on_weekend?, next_weekday, prev_weekday, next_day, prev_day. Perhaps you had even implemented them before yourself! Good thing Rails will have them out of the box now :)

has_secure_token in Active Record

Rails will ship with a new Active Record macro for generating base 58 tokens out of the box. There's probably a large amount of applications already using this feature. As of the next major release you won't need to add another dependency or implement it yourself.

Fixed More conventional filenames for mailers

Mailer generators now appends the _mailer suffix in the filename just like controller and jobs generators.

Rails 5.0 deprecations clean up

This week Rails got some more love with this major clean up (339 additions and 1,433 deletions) on its master branch. There's still some deprecations left though as the team figures how to best address them.

One More Thing™ Automatic type casting deprecated in Arel

Watch out library authors! Sean Griffin put a lot of effort into improving Arel extensibility. Please get in touch with him if you need APIs to help your use case. (See also these follow-up commits.)

Wrapping up

That's all for This week in Rails. As always, there are more changes than we have room to cover here, but feel free to check them out yourself!

Rails 4.2: Active Job, Asynchronous Mails, Adequate Record, Web Console, Foreign Keys

Fri, 12/19/2014 - 21:00

We come bearing gifts! It's Rails 4.2, and the final version is ready just in time for Christmas. It's full of great toys, useful gizmos, and polished edges, courtesy of a fantastic community of merry elves who've been coding away with jolly glee for months.

This is probably also the most well-tested new major release of Rails in a long time. Through four betas and three release candidates, tons of people have helped ensure that regressions and bugs have been caught. Since the first beta, we have some 1600+ commits of spit and polish applied. So you have good reason to be excited!

To recap, here's a walkthrough of the major new goodies:

Active Job, ActionMailer #deliver_later

The headline feature for Rails 4.2 is the brand new Active Job framework, and its integrations. Active Job is an adapter layer on top of queuing systems like Resque, Delayed Job, Sidekiq, and more. You can write your jobs to Active Job, and they'll run on all these queues with no changes.

With an always-configured queue in place (though the default is just an inline runner), we can build on top of that where it makes sense. And the first place it makes sense is to send Action Mailer emails asynchronously. So we're introducing the #deliver_later method, which will do just that: Add your email to be sent as a job to a queue, so you don't bog down the controller or model. Voila!

The cherry on top is our new GlobalID library. It makes it easy to pass Active Record objects to jobs by serializing them in a generic form. This means you no longer have to manually pack and unpack your Active Records by passing ids. Just give the job the straight AR object, and it'll serialize it using GlobalID, and deserialize it at run time. So much easier!

Special thanks go out to Cristian Bica and Abdelkader Boudih for their outstanding work bringing this trinity of improvements to Rails!

Adequate Record

Aaron Patterson is always hunting for performance bounties in Rails, and with an improvement project called Adequate Record for Active Record, he's come up good. A lot of common queries are now no less than twice as fast in Rails 4.2! This is a great step forward for performance. While computers are constantly getting cheaper and performance is improving, nobody ever said "hey, get that free speed out of my framework". So there you go: Some free speed, buddy!

Web Console

Out of the wonderful Google Summer of Code for Rails campaign comes Web Console, which gives you a development console to inspect the state of affairs on all exception pages! It even allows you to jump between the different points in the backtrace, and you'll be able to inspect things right at that point.

It's a wonderful improvement to the debugging workflow. Thanks to Genadi Samokovarov and Ryan Dao for their work on this project.

Foreign Keys

Rails has long had a tumultuous relationship with foreign keys, but the drama days are now over. If you want to have foreign keys, you can have foreign keys, and Rails will still smile as it takes your order. The migration DSL gets add_foreign_key and remove_foreign_key and the standard schema.rb dumper will support maintaing these declarations. Foreign key support starts out as an exclusive to the MySQL and PostgreSQL adapters.

And so much more...

The above are just the highlights. We have many more goodies packed into this release than that. You can read a great summary in the release notes.

Maintenance consequences and Rails 5.0!

As per our maintenance policy, the release of Rails 4.2 means bug fixes will only apply to 4-2-stable, regular security issues to 4.2.x, 4.1.x, and severe security issues to 4.2.x, 4.1.x, and 3.2.x. In addition to these already stated commitments, the honorable Rafael França has agreed to also apply bug fixes to 4-1-stable. So everyone still on 4.1 and unable to move quickly can thank Rafael!

Rails 4.2 also marks the last big release in the 4.x series. With this release out, we're now working towards the big Rails 5.0! This means rails/master is now targeting 5.0.

Rails 5.0 will target Ruby 2.2+ exclusively. There are a bunch of optimizations coming in Ruby 2.2 that are going to be very nice, but most importantly for Rails, symbols are going to be garbage collected. This means we can shed a lot of weight related to juggling strings when we accept input from the outside world. It also means that we can convert fully to keyword arguments and all the other good stuff from the latest Ruby.

The release target for Rails 5.0 is currently Fall of 2015. So there's a while yet, but we're putting this out there for people to know, so gem maintainers and other Ruby implementations can know where we're going. We'll be working on putting out somewhat of a road map for the features when that's become a bit clearer.

Thanks to all and happy holidays!

It continues to be a pleasure and an honor to be involved with the amazing Ruby on Rails community – both contributors and users. The collaboration and resulting quality has never been better. Have a great holiday season and New Year's, and we'll see you all with more delicious releases in 2015!

[ANN] Rails 4.2.0.rc3 has been released!

Sat, 12/13/2014 - 03:00

Happy Friday everyone!

The Rails team has just released the third Release Candidate of Rails 4.2.0 today. For an overview of all the major changes in the 4.2 series, please refer to the release notes.

The RC3 release includes a few more minor patches over RC2. You can refer to the diff on Github for a full list of changes.

We would like to thank you again for assisting our team in testing the release candidates. Please continue to report any issues you discovered to our issue tracker and/or notify the maintainers of the relevant gems and plugins.

So far, we still haven't identify any major regressions for this release, meaning that we are still on track for our target to release the final version of 4.2.0 before Christmas time.

[ANN] Rails 4.2.0.rc2 has been released!

Fri, 12/05/2014 - 23:00

Happy Friday everyone!

The Rails team has just released the second Release Candidate of Rails 4.2.0 today. For an overview of all the major changes in the 4.2 series, please refer to the release notes.

The RC2 release includes some patches for a few minor issues that was reported in the last week. It also includes some improvements to the documentation and some enhancements that decreases the verbosity of the Active Job logs. You can refer to the diff on Github for a full list of changes.

We would like to thank you again for assisting our team in testing the release candidates. Please continue to report any issues you discovered to our issue tracker and/or notify the maintainers of the relevant gems and plugins.

If no other major issues are found, we expect to release the final version of 4.2.0 very soon, just in time for Christmas!

[ANN] Rails 4.2.0.rc1 has been released!

Fri, 11/28/2014 - 18:00

Happy Black Friday everyone!

The Rails team is very excited to announce that the first Release Candidate of Rails 4.2.0 has been released today. For an overview of all the major changes, please refer to the release notes.

We would like to thank everyone who have assisted our team in testing the beta and smoothing out all the rough edges. During the beta period, we have logged over 1500 commits by over 60 contributors and over 100 tickets and pull requests on GitHub.

In particular, thanks to contributors who have assisted in testing the release in their Real World™ applications, we have identified and addressed a number of performance issues since the last beta release.

With the release candidate out the door, we are now much closer to the final release of 4.2.0. Please consider testing this release with your applications if you haven't already – you can read the upgrade guide for detailed instructions. If you found any problems while upgrading, please report them to our issue tracker and/or notify the authors of the relevant gems and plugins.

Thank you all again, this release would not be possible without your help!

One More Thing™

The release of the first RC for the 4.2.0 series also marks the beginning of Rails 5 development. The 4-2-stable branch has been created today and all changes on the master branch will be targeted for Rails 5.0 and backported according to our maintenance policy. Read more about the grand plans for Rails 5!

Rails 4.0.11.1 and 4.1.7.1 have been released

Wed, 11/19/2014 - 19:16

Hi everyone!

Rails 4.0.11.1 and 4.1.7.1 have been released!

These two releases contain only security fix that was already released as 4.0.12 and 4.1.8. You can read more about the issue here (CVE-2014-7829).

4.0.12 and 4.1.8 were inadvertently based on their respective stable branches, and so incorporated additional changes beyond those necessary to resolve the security issue. In keeping with our security policy, it is our intention to include only the minimum necessary changes in security releases, to ensure everyone can upgrade without fear of regressions. As those releases included unrelated changes, we are providing new releases, based on the previous release, which contain only the security fix itself.

If you have already successfully upgraded to 4.0.12 or 4.1.8, no further action is required. Otherwise, if you are still on 4.0.11 or 4.1.7, please do upgrade to 4.0.11.1 or 4.1.7.1 at your earliest convenience.

The 3.2.21 release did incorporate a second change, but that change was intended: by policy, minor security-relevant bugs (which do not independently warrant a security release) are occasionally backported to 3-2-stable, and rolled into a subsequent security release.

The commits for 4.0.11.1 can be found here, and the commits for 4.1.7.1 can be found here.

Here are the checksums for 4.0.11.1:

Rails 3.2.21, 4.0.12, and 4.1.8 have been released

Mon, 11/17/2014 - 15:44

Hello everyone!!! It's that time again.

I would like to announce that Rails 3.2.21, 4.0.12, and 4.1.8 have been released. These releases contain a security fix where the existence of arbitrary files on the file system can be leaked, but the contents of the file will not be leaked. The issue generally only impacts people who are using Rails to serve static assets, and will generally not impact people who use a proxy to serve static assets. This issue is similar to CVE-2014-7818, but is slightly different. You can read more about the issue here (CVE-2014-7829).
