Getting hash with symbol as keys for mongo in rails

Question

The Mongo ruby driver seems to get put your results into a hash with strings as keys. Is there a way to tell it to convert the keys into symbols instead?

Answer 1

If you have a Hash that is keyed with strings, and you want to be able to use Symbols as keys to access its values, you can use a HashWithIndifferentAccess. If you are not using Rails, you can get this class via the ActiveSupport gem.

my_hash = { 'name' => 'Joe', 'email' => 'joe@schmoe.com' }
my_hash = HashWithIndifferentAccess.new my_hash
puts my_hash[:name] # "Joe"
