Hi everyone,
A simplified version of my model looks like this:
class Schedule(models.Model):
start_time = models.DateTimeField('Start Time')
end_time = models.DateTimeField('End Time')
event = models.CharField(maxlength=100)
Now, I want to select all records whose duration (end_time -
start_time) is more than 2 hours.
I tried a custom method in the model like this which returns the
duration but cannot figure out how to use it in queryset filters.
class Schedule(models.Model):
start_time = models.DateTimeField('Start Time')
end_time = models.DateTimeField('End Time')
event = models.CharField(maxlength=100)
def event_duration(self):
return self.end_time-self.start_time
Could anyone suggest the best way to do this?
Thanks,
Sambhav
