#deep_symbolize_keys ⇒ Object
Returns a new hash with all keys converted to symbols, as long as they respond to to_sym
. This includes the keys from the root hash and from all nested hashes and arrays.
hash = { 'person' => { 'name' => 'Rob', 'age' => '28' } }
hash.deep_symbolize_keys
# => {:person=>{:name=>"Rob", :age=>"28"}}

#deep_transform_keys(&block) ⇒ Object
Returns a new hash with all keys converted by the block operation. This includes the keys from the root hash and from all nested hashes and arrays.
hash = { person: { name: 'Rob', age: '28' } }
hash.deep_transform_keys{ |key| key.to_s.upcase }
