Rails: Refactoring - json["data"]["counts"]["followed_by"] if json && json["data"] && json["data"]["counts"] && json["data"]["counts"]["followed_by"]

Question

Question is pretty much in the title. What's the best way to refactor something like below?

json["data"]["counts"]["followed_by"] if json &&  json["data"] && json["data"]["counts"] && json["data"]["counts"]["followed_by"]

I want to return nil unless json["data"]["counts"]["followed_by"] exists.

Answer 1

You can use try :

json.try(:[], 'data').try(:[], 'counts').try(:[], 'followed_by')

Answer 2

I tend towards the andand gem over long try chains, e.g.,

 json.andand['data'].andand['counts'].andand['followed_by']

IMO it just looks nicer.
