Get count of items that have a value in Ruby

I have an Array like so:

search_results = [{policy: {isActive: true}}]

And I want to get the count of search_results where isActive is true. In this case, the Array only contains 1 item whose policy isActive object is true.

I tried with:

search_results.group_by { |x| x.policy.isActive }.count

However I always get 1 back. Regardless if isActive is true or false.

You access hash key-value pair with [], not ..

search_results.count { |hash| hash[:policy][:isActive] }

If you're using newer Ruby version, you can make use of Hash#dig (Ruby 2.3+) and Enumerable#sum (Ruby 2.4+):

search_results.sum { |hash| hash.dig(:policy, :isActive) }
