Re: Making functions callable

For the default value to work as you expect, do this:

def view(request, year=None):
    if year is None:
        year = today.year()


Kwarg defaults are evaluated when the module is interpreted for the first time.

Hi Guys,

I'm running into a problem with django(I guess this would also affect Python in general) where if I create a view eg
def view(year=today.year())
The year is never re-evaluated until the server is reloaded/restarted

I'm trying to figure out how to make a callable method accessible as a property if this is even possible to try and rectify this(not sure if this is even the correct approach). I've had a look at some magic methods but can't figure it out.

Basically I want to make eg

def year(something):
    return 'blah'

Accessible using object.year as well as object.year()

Any pointers/ideas etc?
