Symbolize Array of Hashes in Ruby

gistfile1.rb

# Deep symbolizes keys in hash
class Hash
  def deep_sybolize_keys(value = self)
    case value
    when Array
      value.map { |v| deep_sybolize_keys(v) }
    when Hash
      symbolize_hash(value)
    else
      value
    end
  end

  def symbolize_hash(value)
    Hash[value.map { |k, v| [k.to_sym, deep_sybolize_keys(v)] }]
  end
end

#Usage:
hash = [{'a' => 'b', 'c' => 'd'}]
hash(&:deep_sybolize_keys)
