A Hashie Hash is simply a Hash that has convenience functions baked in such as stringify_keys that may not be available in all libraries.
Converts a mash back to a hash (with stringified or symbolized keys)
# File lib/hashie/hash.rb, line 18 def to_hash(options = {}) out = {} keys.each do |k| assignment_key = if options[:stringify_keys] k.to_s elsif options[:symbolize_keys] k.to_s.to_sym else k end if self[k].is_a?(Array) out[assignment_key] ||= [] self[k].each do |array_object| out[assignment_key] << (Hash === array_object ? flexibly_convert_to_hash(array_object, options) : array_object) end else out[assignment_key] = (Hash === self[k] || self[k].respond_to?(:to_hash)) ? flexibly_convert_to_hash(self[k], options) : self[k] end end out end
The C generator for the json gem doesn't like mashies
# File lib/hashie/hash.rb, line 41 def to_json(*args) to_hash.to_json(*args) end
Convert this hash into a Mash
# File lib/hashie/hash.rb, line 13 def to_mash ::Hashie::Mash.new(self) end
# File lib/hashie/hash.rb, line 47 def flexibly_convert_to_hash(object, options = {}) if object.method(:to_hash).arity == 0 object.to_hash else object.to_hash(options) end end
