Class Method Details

.deep_symbolize_keys(object, &block) ⇒ 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' } }

Castle::Hash.deep_symbolize_keys(hash)
# => {:person=>{:name=>"Rob", :age=>"28"}}
