如何计算Django中两个日期之间的差异 [英] How to calculate diff between two dates in django

问题描述

我想计算当前日期和上一个日期之间的天数差。
i正在尝试使用此代码

I want to calculate days difference between current date and previous date. i am trying this code

requiremntObj = CustomerLeads.objects.all()
a = datetime.datetime.now().date()

for i in requiremntObj:
    date1=i.posting_date
    diff = a-date1
    print diff

我收到错误的错误操作数类型-：'datetime.date'和'unicode '

对于当前日期，我正在获取datetime对象，对于date1，我正在获取unicode。

For current date i am getting datetime object and for date1 i am getting unicode.

posting_date = models.DateField()

推荐答案

如果您有 DateTimeField ，则可以使用：

If you have DateTimeField you can use:

delta = datetime.now().date() - posting_date
print delta.days

如果是字符串，则必须转换：

If it is string, then you have to convert:

from datetime import datetime
date_format = "%m/%d/%Y"
a = datetime.strptime(str(datetime.now().date()), date_format)
b = datetime.strptime(str(posting_date), date_format)
delta = b - a
print delta.days
