IMHO, the example's code is good, but not cool enough to be put in the
book. Every programmer saw those ordinary if...elif...elif...else
cliche in their first program language book before. People can
probably write their own if...elif...else in less time, than STFW or
RTFM to find our prettydate().
So, we need some extra flavor to compensate the time a guy spent to
find our prettydate(). How about making it i18n-friendly? Something
like this.
class PrettyDate(object):
def __init__(self,T):
self.T=T #
def __call__(self, d):
dt = datetime.now() - d
if dt.days >= 2*365:
return self.T('%d years ago') % int(dt.days / 365)
elif ...:
......
Then, in the model we can initialize an instance by:
prettydate = PrettyDate(T)
In controller we can do:
prettydate(d)
Of course developers need to localize their own language strings in
their own environment.
Just my $0.02
