Re: order_by on the basis of time difference (updated_at - created_at)

This is nice idea, but I can't change the model, as discussed by teammates, i need to figure out any other way to do it on the go.

won't be possible like this, It will be easy if you have another entry in models which stores the difference between updated and created.

You can update that field whenever an object is updated. And then can run order_by on that field directly

class ExampleModel(models.Model):

is_active = models.BooleanField(default=True)

created_at = models.DateTimeField(auto_now_add=True)

updated_at = models.DateTimeField(auto_now=True)

I want to query on UserModel such that the Query set which I get should be orderable in terms of time difference of updated_at - created_at,

I tried

ExampleModel.objects.all().order_by('updated_at' - 'created_at')
but this is not working
it throws, TypeError: unsupported operand type(s) for -: 'str' and 'str'
