我想在Django的日期字段中添加一些工作日。这是针对不同产品的不同交货时间的产品订购，我们希望为每种产品生成目标日期。
例如，产品X可能需要10个工作日才能交付，如果此产品在星期五日期01/03/2013订购，则目标日期最终应该是星期五15/03/2013（它将订购日期排除为一天）。
我已经浏览了一下，似乎有一些python库可以做到这一点，但这一切看起来都过于复杂。我认为有一种相当简单的方法可以做到这一点。

我现在正在使用BusinessHours PyPi包，但似乎遇到了一些问题。
他们举例说明了如何调用包。
eg: Class: BusinessHours(datetime1,datetime2,worktiming=[9 ,18],weekends=[6,7],holidayfile=None)
Class Parameters:
datetime1 - The datetime object with the starting date.
datetime2 - The datetime object with the ending date.
worktiming - The working office hours . A list containing two values start time and end time
weekends - The days in a week which have to be considered as weekends sent as a list, 1 for monday ... 7 for sunday.
holidayfile - A file consisting of the predetermined office holidays.Each date starts in a new line and currently must only be in the format dd-mm-yyyy
from BusinessHours import BusinessHours
from datetime import datetime
testing = BusinessHours(datetime(2007,10,15),datetime.now())
print testing.getdays()
使用此信息，我制作了以下测试脚本
from BusinessHours import BusinessHours
from datetime import datetime
holidaytextfile = 'holidays.txt'
testing = BusinessHours(datetime(2013,02,01),datetime(2013,02,28),worktiming=[9 ,18],weekends=[6,7],holidayfile=holidaytextfile)
print testing.getdays()
我的假日文件包含以下内容（仅在2月份的随机工作日）
07-02-2013
当我运行脚本时，我收到以下错误。
Traceback (most recent call last):
File "business_days", line 9, in ?
print testing.getdays()
File "/usr/lib/python2.4/site-packages/BusinessHours.py", line 63, in getdays
holidate = date(int(year) , int(month) , int(day))
NameError: global name 'date' is not defined
这是包中的代码部分。
60 for definedholiday in definedholidays:
61 flag=0;
62 day , month , year = definedholiday.split('-')
63 holidate = date(int(year) , int(month) , int(day))
64 for weekend in self.weekends:
65 #check if mentioned holiday lies in defined weekend , shouldnt deduct twice
66 if(holidate.isoweekday==weekend):
67 flag=1;
68 break;
我感谢任何人给予我的帮助，我的Python版本是2.4.3
