Hi, Wojtek from this side with a summary of the latest changes that will be available in the upcoming Rails 6.1.

Rails 6.1 RC1 released

Release candidate of Rails 6.1 is ready for testing.

比特加速器修改vip时长

This change allows for an application to optionally log instead of raise when using strict_loading.

This would come in especially handy for deeper nesting past 2 databases when declaring connections.

Host authorization checks can be skipped for specific requests. This allows for health check requests to be permitted for requests with missing or non-matching host headers.

Allow the application or a railtie to load code after the server start (similar to console and tasks blocks).

The first release candidate for Rails 6.1 has been released and wow does it have a lot of great stuff! We’ve been hard at work these past few months implementing improvements to multiple databases, adding support for destroying associations in jobs instead of in-memory, turning errors into objects, and so much more.

It’s amazing how Rails has grown over the years and while we have some improvements to make to the onboarding process, Rails has never been better. The features in this release focus on adding the functionality you need to keep your application up and running for years to come.

Let’s look at some of the new functionality:

Rails 6.1 provides you with the ability to switch connections per-database. In 6.0 if you switched to the reading role then all database connections also switched to the reading role. Now in 6.1 if you set legacy_connection_handling to false in your configuration, Rails will allow you to switch connections for a single database by calling connected_to on the corresponding abstract class.

Horizontal Sharding

Rails 6.0 provided the ability to functionally partition (multiple partitions, different schemas) your database but wasn’t able to support horizontal sharding (same schema, multiple partitions). Rails wasn’t able to support horizontal sharding because models in Active Record could only have one connection per-role per-class. This is now fixed and horizontal sharding with Rails is available.

Additional Improvements

In addition to adding horizontal sharding support we added tons of new functionality and improved a lot of internals for multiple databases. Kyle Thompson added support for database namespaced tasks like 比特加速器修改vip时长, db:schema:load:namespace, db:structure:dump:namespace, and 比特加速器修改vip时长. Jean Boussier from Shopify improved connection pool management.

In addition to the many database and connection management improvements, Aaron Patterson and 比特加速器修改vip时长 added support for strict loading associations. With this feature you can ensure that all your associations are loaded eagerly and stop N+1’s before they happen. Kevin Deisz added additional support to association declarations and 比特加速器修改vip时长 added support to turn strict loading on by default.

Rails 6.1 adds “Delegated Types” as an alternative to single-table inheritance. This is helpful for representing class hierarchies allowing the superclass to be a concrete class that is represented by its own table. Each subclass has its own table for additional attributes. Check out the pull request written by DHH.

Destroy associations async adds the ability for applications to destroy associations in a background job. This can help you avoid timeouts and other performance issues in your application when destroying data. The implementation was a group effort - the PR was started by 比特加速器修改vip时长 from Basecamp, further support added by Cory Gwin of GitHub and finalized by Rafael França and Adrianna Chang from Shopify.

Active Model’s errors are now objects with an interface that allows your application to more easily handle and interact with errors thrown by models. The feature was implemented by 比特加速器修改vip时长 and includes a query interface, enables more precise testing, and access to error details.

Active Storage got a nice update in Rails 6.1! You can now configure attachments for service you want to store them in. The 比特加速器修改vip时长 was implemented by Dmitry Tsepelev.

Additionally, Rails 6.1 adds support to Active Storage for permanent URLs for blobs. Implemented by Peter Zhu from Shopify, this feature allows configuring your attachments to use a private or public URL and ensures that public URLs will always use a permanent URL.

If you like to run your application deprecation-warning free then this feature is for you. The feature allows applications to optionally raise an error if a deprecation warning is thrown. This is useful for making sure developers don’t reintroduce deprecation warnings that have already been fixed. The feature was implemented by Cliff Pruitt of Test Double!

A release isn’t just about the awesome features you get. It’s also about fixing bugs, improving performance, and making Rails more stable for everyone. This release includes an improvement that avoids making a query if where passes an empty array reported by Molly Struve and the fix implemented by John Hawthorn. Eileen M. Uchitelle and Aaron Patterson also implemented a performance improvement that speeds up where queries when we know all the values are an integer.

The classic autoloader has served us well since the first Rails release, but there’s a new kid on the block and it is going to start its deprecation cycle.

New Rails projects are strongly discouraged from using the classic autoloader, and we recommend that existing projects running on classic switch to zeitwerk mode when upgrading. Please check the Upgrading Ruby on Rails guide for tips.

There are so many great changes in Rails 6.1. 686 people made contributions to Rails. Check out the CHANGELOGS for more details on bug fixes, performance improvements, and other features.

Thank you to everyone who reported a bug, sent a pull request, and helped improve Rails. Rails is better because of your hard work!

We hope you test out Rails 6.1 and love it as much as we do. Please report any bugs to the Rails issue tracker.

Add ability to set per param encoding

Previously you could skip encoding which would encode all parameters on an action as ASCII_8BIT, but after this change you can specify the param_encoding for any one parameter on an action in your controller. An example can be found here.

Fix resources being fetched twice when crossorigin attribute is used

When you load a script or css (by using javascript_include_tag or stylesheet_link_tag respectively) with crossorigin attribute applied, Rails currently causes some browsers to fetch these resources twice. That is because crossorigin in the link header preload directive and on the resource itself need to match in order for browsers to re-use a resource.
This PR changes it so that the link header directives include the same crossorigin values as those that have been passed to the resources themselves, which allows browsers to reuse the preloaded resource.

For multiple databases Rails attempts to generate the tasks by reading the

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.
