Yo DawgI heard you like ActiveRecord Callbacks

So I added a callback that will call you backWhen your callback calls my callback

The AR Callbacks Problem

A Stop Gap Solutionhttps://github.com/godaddy/activerecord-delay_touching

ActiveRecord::Base.delay_touching do # touch_all_the_thingsend

Be more explicit with Service Objects

OptionValueUpdater.new(option_value).call

● Explicit, clear business logic● No hidden side effects● No magic to understand● Aggregation of bulk updates

My time with Rails is up (Piotr Solnica)http://solnic.eu/2016/05/22/my-time-with-rails-is-up.html

“People are attracted by Rails because it gives you a false sense of simplicity, whereas what really happens is that complexity is being hidden by convenient interfaces. [...] ActiveRecord is just one, representative example, [...].”

All Things in Moderation

Rails has won: The Elephant in the Room (Fabio Akita)http://www.akitaonrails.com/2016/05/23/rails-has-won-the-elephant-in-the-room “[…] for all intents and purposes, Active Record still does much better than average. But if you're big, you should be careful. That's all.”
