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

Question

I have a Ruby hash which looks like:

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

I would like to convert it to:

{ :id

Here's my two cents,

my version of symbolize_keys_deep! uses the original symbolize_keys! provided by rails and just makes a simple recursive call to Symbolize sub hashes.

  def symbolize_keys_deep!(h)
    h.symbolize_keys!
    h.each do |k, v|
      symbolize_keys_deep!(v) if v.is_a? Hash
    end
  end
