Instance Method Details
#as_json ⇒ Object
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"

#to_json(*args) ⇒ Object
Returns a JSON string representing self
:
require 'json/add/datetime'
