How to put timedelta in django model?

Question

With inspectdb I was able to get a \"interval\" field from postgres into django. In Django, it was a TextField. The object that I retrieved was indeed a timedelta object!

Answer 1

First, define your model:

class TimeModel(models.Model):
    time = models.FloatField()

To store a timedelta object:

# td is a timedelta object
TimeModel.objects.create(time=td.total_seconds())

To get the timedelta object out of the database:

# Assume the previously created TimeModel object has an id of 1
td = timedelta(seconds=TimeModel.objects.get(id=1).time)

Note: I'm using Python 2.7 for this example.
