I have a lot of similar resources in my Rails application, and I have currently DRY'd up the code using controller inheritance. I see that there is a directory called concerns under the controller folder, where I could potentially write similar concerns (such as archiving, activate/deactivate etc.) I can probably write mixins too.
Is there a preferred approach to DRY up the controller code? Is there any downside in using inheritance, or are there any advantages using other techniques?

In my experience, it depends on what you want the code to do. I've only used concerns for simple controller-independent methods, such as before_action
or something
I would use inheritance if your controller's methods are able to rely on a super class or something. My experience so far has lead me to use inherited_resources - a DRY way to create controller inheritance
