Question

我目前正在使用python django Web框架中的Calendar。我正在尝试打印一些内容并引发以下错误：

TypeError：强制转换为Unicode：需要字符串或缓冲区，找不到

我见过有类似问题的人，但没有'长'的人和一个有效的解决方案.... 回溯：

这是我的代码：

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)]
            )

我试图看看self.holiday的设置是什么...我尝试了一个for循环，因为我认为这将是一个项目列表，它引发了同样的错误。以下是调用上述

的视图

@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

谢谢！

Answer 1

问题似乎出现在您的Holyday模型的 str 或 unicode 方法中。那些方法应该返回resp。一个字符串或unicode对象，看起来它返回一个很长的（可能是pk - 狂野的猜测...）

错误：强制转换为Unicode：需要找到字符串或缓冲区
