As always, huge thanks to the many contributors who helped with this release.

Hi there! This is Kir from chilling Ottawa, bringing you another edition of This Week in Rails. Let’s dive in.

Featured

🎉 This Week’s Rails contributors! 🎉

We had 21 awesome people who helped make Rails better this week, with one first-time contributor! Would you like to help as well? Head over to the 👉 issues list.

New

🎉 Rails 4.2.9.rc2, 5.0.4 and 5.1.2rc1 have been released 🎉

It’s your chance to help us discover bugs in 4.2.9 and 5.1.2 release candidates. Also, Rails 4.2.9 will be the last release in 4.2 series, so it’s time to upgrade if your app is still running on Rails 4.

Perf

Use bulk INSERT to insert fixtures

Inserting fixtures in test environment became significantly faster by using one bulk INSERT query instead of many single INSERTs.

Fixed

current_page? helper now works from within a Rails Engine

Due a bug related to a trailing slash, current_page? helper always returned false while it was supposed to return true when it was called from a Rails Engine route.

Keep INNER JOIN when merging relations

Now you can safely merge two ActiveRecord relations both having a JOIN. Previously, that would to query with LEFT OUTER JOIN instead of INNER JOIN.

That’s it for this week, as always, we couldn’t cover all of the changes, but feel free to check all the commits from this week.

Until next week! 👋👋

Hi there! This is Andy, bringing you another edition of This Week in Rails. Let’s dive in.

Featured

🎉 This Week’s Rails contributors! 🎉

We had 23 awesome people who helped make Rails better this week, with 4 first-time contributors! Would you like to help as well? Head over to the 👉 issues list.

New

Allow mailers to configure their delivery job

In some situations, a user may want to configure the delivery job in order to have better control over errors. This adds an option to make that possible.

Perf

Improve performance of mass assignments

This change makes a small improvement to the performance of initializing an ActiveModel instance. The other interesting thing I learned about was the “magic comment” # frozen_string_literal: true. Check the PR for details.

Fixed

Don’t map id to primary key in raw_write_attribute

The hash provided to update_columns is turned into an UPDATE query. Passing an id key resulted in an update to the id column, even if the model uses a different primary key. This fixes that!

Docs

Docs for #delegate_missing_to

A newer feature, now with documentation explaining how and when to use delegate, and delegate_missing_to.

That’s it for this week, as always, we couldn’t cover all of the changes, but feel free to check all the commits from this week.

Until next week! 👋👋

Hello everyone! Prathamesh here bringing you the latest news from the Rails world. Let’s get started 🚅

Featured

🎉 This Week’s Rails contributors! 🎉

We had 21 awesome people who helped make Rails better this week. Two of them contributed for the first time ever! Would you like to help as well? Head over to the 👉 issues list.

New

💪 mattr_accessor gets the default option 💪

Followup to adding the default option to the class_attribute macro, it is now added to mattr_accessor family of methods as well.

It can be used as follows:

mattr_accessor :always_write_cookie, default: false

💪 Write multiple cache entries at once with write_multi 💪

A new method write_multi has been added to the cache stores which writes multiple cache entries at once.

For eg.

Rails.cache.write_multi foo: ‘bar’, baz: ‘qux’ The default implementation just calls write_entry one by one for each entry but specific cache stores can override this behavior as per their ability of doing bulk writes.

Fixed

⚡️ Generate field ids in collection_check_boxes and collection_radio_buttons ⚡️

This change fixes an issue with collection checkboxes and radio boxes where clicking on the labels was not selecting the options because the input elements did not have proper id attribute with respect to their labels.

✨ Fix partial cache logging getting attributed to wrong partials ✨

This commit fixes an issue with the cache hit/miss log markers being applied to wrong partials.

That’s it for this week, as always, we couldn’t cover all of the changes, but feel free to check all the commits from this week.

Until next week! 👋👋

Hello everyone! This is Roque bringing you the latest news from the Rails world.

Featured

This Week’s Rails contributors!

We had 32 people who helped make Rails better this week. Three of them contributed for the first time ever! If you would like to help out, check the issues list.

Allow a default value to be declared for class_attribute

Rails will now make it easier to set default values to class attributes like class_attribute :timeout, default: 5

Replace therubyracer with mini_racer

New apps generated with JavaScript and Sprockets support will use mini_racer for the Ruby platform. A faster and more reliable interpreter.

New

Add previous and next day of week API to Active Support

The methods prev_occurring and next_occurring expect a day of the week and return the appropriate value based on the DateTime, e.g. DateTime.now.prev_occurring(:monday).

Fixed

Fix number_to_human round calculation

This fix a regression introduced in Rails 5, where a case like number_to_human(1_000_000, units: { unit: 'meter', thousand: 'kilometer' }) would return "1" instead of "1000 kilometer".

Fix pluralization of uncountable expressions when given a locale

Previously, methods like pluralize and singularize would only use the English uncountable rules rather then the ones for the locale that was passed.

Rename primary key index from rename_table

Formerly, rename_table would only rename primary key index if the column’s data type was sequential. Tables with primary keys with types like UUID would still keep the old name.

Improved

Allow additional options for poltergeist or capybara-webkit in System Tests

If using poltergeist or capybara-webkit, driven_by will register it as the driver and set additional options passed via :options param.

Please refer to drivers documentation to learn what options can be passed.

That’s it for this week, as always, we couldn’t cover all of the changes, but feel free to check the commits if you are interested. Until next week!
