민첩성 유형의 기본 날짜를 설정하는 방법 schema.datetime?

Question

저는 Plone 4.3.10에 Python 2.7.x를 사용하여 민첩성 유형을 쓰고 있습니다.

설정을 필드 schema.Datetime의 기본 날짜로 설정합니다. 내가 여기에 문제가 datetime.datetime(2016, 9, 6, 14, 34, 51, 812271)처럼, 나는 사용하여 시도 http://docs.plone.org/4/en/external/plone.app.dexterity/docs/advanced/defaults.html

이 팁을 따라 그 datetime.datetime.now()의 출력 생각

:

import datetime 
agoradatetime = datetime.datetime.now() 

directives.read_permission(uploded_at="cmf.ManagePortal") 
directives.write_permission(uploded_at="cmf.ManagePortal") 
uploded_at = schema.Datetime(
    title=_(u"Data de Upload"), 
    required=True, 
    default=agoradatetime, 
) 

나는 내가이 오류가 발생했습니다 default=agoradatetime을 설정하는 경우 :

from DateTime import DateTime 
datenow = DateTime() 

그러나 오류 WrongType있어, 우는 소리 참조 :

WrongType: (DateTime('2016/09/06 14:39:29.021494 GMT-3'), <type 'datetime.datetime'>, '')

documentaion 말 : 파이썬 날짜 시간 : Here 및 Here을.

하지만 오류가있어 :

TypeError: Error when calling the metaclass bases 
unhashable type: 'list' 

그래서 내가 필요가있는 무엇을? 나는 사용자가 Plone에서 Contenttype Dexterity를 ​​만들 때 필드 "uploaded_at"을 "날짜와 시간"으로 구성해야합니다.

당신이 사용하는 문서 링크가 명확 defaultFactory하지 default을 사용하여 역 추적하고를 얻기 위해 호출되는 함수해야 사용할 수있는 값 필요할 때마다 기본값으로 설정됩니다. 제 제안은 defaultFactory도 사용하는 것입니다.

은 BTW : default가 작동하지 않는 이유는 모르겠지만,이 일을해도 결과는 아마 예상하지 못한 일이 될 것입니다 다음 agoradatetime이 모듈 수준에서 계산, 즉 평균 조프에 한 번 계산 된 날짜입니다 시작.
