Some sample code excerpts, before my question:
(this code is incomplete, but should give the idea of where I'm headed)
class Rateable(meta.Model):
value = meta.IntegerField()
def current_rating(self):
try:
r = self.get_ratee_list()
except:
return "None"
n = sum = 0
for rr in r:
n = n + 1
sum = sum + rr.value
if n == 0:
return "None"
return sum/n
class Rating(meta.Model):
value = meta.IntegerField()
ratee = meta.ForeignKey(Rateable)
rater = meta.ForeignKey(User)
class Place(Rateable):
class Thing(Rateable):
Now, I've easily writen templates that show Places or Things and that
show the ratings for each using {{ object.current_rating }} (as
appropriate, of course). But, I'm trying to figure out how to write a
template that would (a) show the rating for this object for user X or
(b) show the rating for this object for the current user.
I can think of a couple of ways to approach this problem, but I don't
know which path is "better"... I could write a custom template tag
that takes "user" as an argument; or I could try to see how else to
pass an argument or a context variable back to a class' method. Or,
perhaps I'm way off base and neither of these paths is right and
there's a much better way to attack this.
I'd appreciate some guidance on how to approach this problem...
Thanks
