datetime.date(2014, 4, 25) is not JSON serializable in Django [duplicate]

Answer 1

I've found this to be invaluable, especially after updating Django from 1.7 to 1.9. Most of this is from the blog http://arthurpemberton.com/2015/04/fixing-uuid-is-not-json-serializable Put this in models.py right under the imports. It'll take care of UUIDs for you too.

from uuid import UUID
import datetime
JSONEncoder_olddefault = JSONEncoder.default
def JSONEncoder_newdefault(self, o):
    if isinstance(o, UUID): return str(o)
    if isinstance(o, datetime.datetime): return str(o)
    return JSONEncoder_olddefault(self, o)
JSONEncoder.default = JSONEncoder_newdefault
