How do I convert a Ruby hash so that all of its keys are strings

Question

I have a ruby hash which looks like:

{ id: 123, name: "test" }

I would like to convert it to:

{ "id" => 123, "name" => "test" }

Answer 1

In pure Ruby (without Rails), you can do this with a combination of Enumerable#map and Array#to_h:

hash = { id: 123, name: "test" }
hash.map{|key, v| [key.to_s, v] }.to_h
