ZPT reverse ordering
I want to list items on a page with the newest at the top. I have got part of the way there with this code: <tr tal:define="thelist python:p.objectValues('Kube')" tal:repeat="subitems python:sequence.sort(thelist, (('bobobase_modification_time',),) )"> Two problems with this though: 1) I want it sorted by the creation date, rather than modification date. 2) I need the results reversed so newest is at the top, not bottom. I suspect I need to create a python script to build the list. Does anyone have the code to do this? Cheers Tom

i think this will help getting it reversed
tal:repeat="subitems
python:sequence.sort(thelist,(('bobobase_modification_time','d esc'),))">
Thanks for your help. I get an error when I try this though: Error Type: TALESError Error Value: exceptions.AttributeError on 'None' object has no attribute 'getitem' in "", at line 160, column 3 If I take out the 'desc' then it works fine. Any ideas? Hang on a minute, I just fixed it! I replaced bobobase_modification_time with bobobase_creation_time, and left out the 'desc'. It now shows the most recent first. T.

l = [ 3 , 2 ] print l [3, 2] print l.sort() None print l [2, 3]
The sort() method modifies the list in-place and returns None. You are trying to iterate over the return value of sort(), which doesn't have a getitem method. The simplest solution is to sort the list after you have a reference to it. Eg: tal:define="l python:[3,2] ; foo l.sort()" As a side effect it creates 'foo' as a reference to None, but that isn't significant. -D -- An anxious heart weighs a man down, but a kind word cheers him up.

I replaced bobobase_modification_time with bobobase_creation_time, and left out the 'desc'. It now shows the most recent first.
I was talking nonsense! The correct result was a fluke. There's no such thing as bobobase_creation_time. I see it's in the collector. I hope it gets implemented soon, I can't imagine it's too big a job. http://collector.zope.org/Zope/188 T.
