Methods DateTime#as_json
and DateTime.json_create
may be used to serialize and deserialize a DateTime object; see Marshal.
Method DateTime#as_json
serializes self
, returning a 2-element hash representing self
:
require 'json/add/datetime' x = DateTime.now.as_json # => {"json_class"=>"DateTime", "y"=>2023, "m"=>11, "d"=>21, "sg"=>2299161.0}
Method JSON.create
deserializes such a hash, returning a DateTime object:
DateTime.json_create(x) # BUG? Raises Date::Error "invalid date"
# File json/lib/json/add/date_time.rb, line 39 def as_json(*) { JSON.create_id => self.class.name, 'y' => year, 'm' => month, 'd' => day, 'H' => hour, 'M' => min, 'S' => sec, 'of' => offset.to_s, 'sg' => start, } end
to_json(*args)
click to toggle source
Returns a JSON
string representing self
:
require 'json/add/datetime' puts DateTime.now.to_json
Output:
{"json_class":"DateTime","y":2023,"m":11,"d":21,"sg":2299161.0}
