I have a duration field in some model:
{{{
My(models.Model):
...
duration = models.DurationField(default=timedelta(seconds=0))
}}}
and I try to increment durations via F expression:
{{{
obj.duration = F('duration') + (now - some_other_datetime)
}}}
as a result, we have a value of the following format in the database:
0:18:30.233251 instead of a big integer one. So this makes that instance
of model completely unusable, any attempt of access raise an exception:
TypeError: unsupported type for timedelta microseconds component: str
