django How to subtract date from django datetime.date class












0















I have a model:



class DateModel(models.Model):
date = models.DateField(default=None, null=True, blank=True)


and I made some object and got it:



date_obj = GroupDate.objects.all().last()
print(date_obj.date)
print(type(date_obj.date))


so that It returned this lines:



2018-11-21
<class 'datetime.date'>


Here my question,



How to get 22 days before date from date 2018-11-21?



Like this:



date_obj = GroupDate.objects.all().last()
some_int = 22
result_date = get_date_from_date(date_obj.date, some_int) # It is just example that I made.
print(result_date) # >>>2018-10-30


How can I do this?

          By using timedelta.



          >>> from datetime import datetime, timedelta
          >>> date_obj = datetime(2018, 11, 21)
          >>> some_int = 22
          >>> result_date = date_obj - timedelta(days = some_int)
          >>> result_date
          datetime.datetime(2018, 10, 30, 0, 0)


          You could also use relativedelta from dateutil which is a more powerful library with more options, docs are linked.



          >>> from datetime import datetime
          >>> from dateutil.relativedelta import relativedelta
          >>> date_obj = datetime(2018, 11, 21)
          >>> some_int = 22
          >>> result_date = date_obj - relativedelta(days =+ some_int)
          >>> result_date
          datetime.datetime(2018, 10, 30, 0, 0)
