Today, while digging routing guides of Ruby on Rails, I spot this new feature which is available in Ruby on Rails 4. Routing Concern is a wonderful concept of re-using routing definitions. I just love how Rails try to reckon on DRY principle. I’ve worked in a project where routes.rb has about 50 lines of definition while the project was progress not more than 20%. There were many similar routing definitions in different scopes (namespaces). Routing Concerns will now enable us write less codes to define application routes.
I’m not going to show how to use it as Rails guide already did the job. I’m simply copying the codes over here.
I’ve also found this blog shared on facebook by one of my friend
