Thanks Daniel!
I didn't realize that "FOO_gt=..." would go to the next. I guess I
was thinking that'd only work with dates, ints, things that have to do
with numbers. (I'm new to this stuff).
Provided what you gave me, I came up with the follow:
def get_prev_by_title(self):
get_prev = Product.objects.order_by('-
title').filter(title__lt=self.title)
try:
return get_prev[0]
except IndexError:
return None
def get_next_by_title(self):
get_next =
Product.objects.order_by('title').filter(title__gt=self.title)
try:
return get_next[0]
except IndexError:
return None
