If all objects have same named attribute for votes (i.e.  
profile.votes, photo.votes) you may use attrgetter() to sort ordinal  
Python list, eg.:

import operator
my_objects.sort(key=operator.attrgetter('votes'))

best practice to have a list of mixed objects

2009-07-02 Thread Bastien

Hello,

I am trying to have a list of various types of objects, for example a
list mixed with users' profile, users' photo... to try to order all
these elements together by the amount of votes they received.

I use the list() function to store each query in a different variable
and then I extend() the list in only one variable.

I'm sure there's a better way to do that, if you have any idea you're
welcome to share it!

Thanks,
Bastien
