Slightly OT, but...
I'm
thank you all! I will do it with raw SQL . thanks for the code.
I hope SQLAlchemy will be implemented soon in django. thank you!

The most efficient way would be to use SQL; this way, the min and max
would fall out as the result of a single query.

hi,
just tried this but doesn't work:
q = ArtistaTag.objects.all()
nums=['']
for tag in q:
num = tag.artista_set.count()
nums.append(num)
max_art = max(nums)
min_art = min(nums)
i get a TypeError unsupported operand type(s) for -: 'str' and 'long' :(

Python already has min and max functions available. Just feed as many
values in a tuple and it will return the min or max
I want to get the maximum and the minimum values of various numbers. Is
the following method the best way to do it?
for tag in q:
num = tag.artista_set.count()
if num_ant:
if num < num_ant:
min_art = num
else:
11 matches
