what is the best way to convert a json formatted key value pair to ruby hash with symbol as key?

Question

I am wondering what is the best way to convert a json formatted key value pair to ruby hash with symbol as key: example:

{ \'user\': { \'name\': \'foo\', \'         


        

Answer 1

The most convenient way is by using the nice_hash gem: https://github.com/MarioRuiz/nice_hash

require 'nice_hash'
my_str = "{ 'user': { 'name': 'foo', 'age': 40, 'location': { 'city' : 'bar', 'state': 'ca' } } }"

# on my_hash will have the json as a hash
my_hash = my_str.json

# or you can filter and get what you want
vals = my_str.json(:age, :city)

# even you can access the keys like this:
puts my_hash._user._location._city
puts my_hash.user.location.city
puts my_hash[:user][:location][:city]
