django - Serialize Timezone Object -

i have model has timezone field using django-timezone-field. stores pytz object in field. receive in response object's zone instance.timezone_field.zone.

with field i'm using readonlymodelviewset , when issuing request, error <dsttzinfo 'us/arizona' lmt-1 day, 16:32:00 std> not json serializable.

it makes sense why i'm getting error, object not json serializable. how serialize use zone subfield?

to show structure of object field, in shell can zone by:

obj = mymodel.objects.get(id=1) obj.timezone.zone "us/pacific" 

i ended making custom serializer field , using zone field on timezone object.

class timezonefield(field):     "take timezone object , make json serializable"     def to_representation(self, obj):         return obj.zone      def to_internal_value(self, data):         return data  class appsettingsserializer(modelserializer):      timezone = timezonefield()      class meta:         model = userappsettings
