python - python bson.errors.InvalidDocument:无法编码对象:datetime.date(2015,3,1)

我有以下功能：

#  this is in a module called 'dbw_lib'
def dateTimeOuput(start_days_back, end_days_back):
    start_delta = datetime.timedelta(days=start_days_back)
    end_delta = datetime.timedelta(days=end_days_back)
    start_date = datetime.date.today() - start_delta
    end_date = datetime.date.today() - end_delta
    return start_date, end_date

def dictByDate(start_days, end_days):
    start_date, end_date = dbw_lib.dateTimeOuput(start_days, end_days)

    date_string = { "created_at": {"$gte" : start_date, "$lt": end_date }  }

    user_id_email_dict = dbw_lib.dbwIdToEmailD(user_coll_obj, date_query = date_string)  # dict of all user ids and emails
    print user_id_email_dict
    quit()

当我运行key_dicts = dictByDate(90, 60)时，我得到以下跟踪：

bson.errors.InvalidDocument: Cannot encode object: datetime.date(2015, 3, 1)

最佳答案

只需更换

datetime.date.today()

具有

datetime.datetime.today()
