錯誤：強制爲Unicode：需要字符串或緩衝區，長時間發現

我目前正在使用python django web框架中的日曆。我想打印的東西，提高了以下錯誤：錯誤：強制爲Unicode：需要字符串或緩衝區，長時間發現

TypeError: coercing to Unicode: need string or buffer, long found

我已經看到了類似問題的人，但不是「長」和有效的解決方案.... 回溯：

這裏是我的代碼：

class HolidayCalendar(HTMLCalendar): 

    def __init__(self, holiday): 
     super(HolidayCalendar, self).__init__() 
     self.holiday = self.holiday_days(holiday) 
     print holiday 
     # for something in holiday: 
     #  print something 

    def holiday_days(self, holiday): 
      field = lambda holiday: holiday.start_date.day 
      return dict(
      [(day, list(items)) for day, items in groupby(holiday, field)] 
      )

我想看看self.holiday被設置爲...我想一個for循環藏漢，因爲我認爲這將是項目的列表，並將其RAI sed同樣的錯誤。這是調用以上的視圖

@login_required 
def holiday(request): 
    # get persons username 
    # get month and year today 
    date_today = datetime.now() 
    year = date_today.year 
    month = date_today.month 
    # get holiday objects in the current month 
    my_holidays = Holiday.objects.order_by('start_date').filter(
     Q(start_date__year=year, start_date__month=month) | Q(end_date__year=year, end_date__month=month) 
    ) 
    cal = HolidayCalendar(my_holidays).formatmonth(year, month) 

    # forms... render template...etc

謝謝！

請發佈完整的回溯。 –

編輯上面:) –

這個問題似乎是在你的'Holyday'模型的'__str__'或'__unicode__'方法。這些方法應該返回resp。一個字符串或unicode對象，它看起來像返回一個很長的（可能是pk - 狂野的猜測......）。 –
