With #RubyOnRails, you can check an #ActiveRecord object’s validations on an attribute using `object.class.validators_on(attribute)`.

The result is an array of validator classes, most of which include an `options` method with the configured options from the definition in the model.

Is it possible to filter out conditional validations from the returned array?

(I have a conditional validation on an attribute and would like to know when it doesn’t apply to a particular instance of the model.)

JRuby's activerecord-jdbc-adapter doesn't yet support ActiveRecord 8. How should a gem which depends on ActiveRecord try to best support both CRuby and JRuby?

Wide Models and Active Record custom validation contexts, by @bensheldon

https://island94.org/2025/04/wide-models-and-active-record-custom-validation-contexts

> This post is a brief description of a pattern I use a lot using when building features in Ruby on Rails apps and that I think needed a name:

> Wide Models have many attributes (columns in the database) that are updated in multiple places in the application, but not always all at once i.e. different forms will update different subsets of attributes on the same model.

How fast can an ActiveRecord SQL query run?, by Fritz Meissner
https://thoughtbot.com/blog/how-fast-can-an-activerecord-sql-query-run

> Your database monitoring (perhaps Amazon RDS performance insights, Skylight, or the #Postgres pg_stat_activity view) is telling you that one particular query in your Rails app is causing heavy load. Unfortunately, it already seems pretty fast. What are the odds that you can get it to run any faster?

It's always great to see @rosa and she talked about her #SolidQueue implementation at #rubycommunityconference in #krakow.

She also gave a shout-out to @bensheldon's #goodjob and mentioned how @getajobmike's @sidekiq is blazingly fast.

New from Julie Kent:

Imaging you have a Rails endpoint that has slow queries AND performs third-party HTTP requests. With Rails async queries, you can perform these operations in parallel—without being an expert in multithreading. 🚀
