Add this line to your application's Gemfile:
gem 'hash_dig_and_collect'And then execute:
$ bundle
Or install it yourself as:
$ gem install hash_dig_and_collect
Hash#dig in Ruby 2.3 completely changed the way I navigate deeply nested hashes. This repo contains an implementation of Hash#dig_and_collect, a new utility method to navigate even more complex nested hashes without messing up your code.
See the details of the why in this Blog post.
