hi there

do you know haow I can sort with tal:repeat

I have the following statement and I'd like to sort them alphabetically:

<tr tal:repeat="obj python: here.objectValues()">

[fyi to TALES newbies: you could also write the above line as tal:repeat="obj here/objectValues"] Zope Book, 2.5 version gives a good example of sorting on p137. Essentially, you can use the sequence.sort method or write your own tiny sort routine. These are both good solutions for medium and hard cases. For simple cases (sort a list on items in it): <tr tal:define="objects here/objectValues; junk python:objects.sort();" tal:repeat="obj objects"> The fact that python never added a sort() function that returns the list in sorted mode (rather than sorting in-place) is annoying to me. Arguably, there are good reasons to sort in-place (memory), but in most cases, it's useful to have both. In a External Method called "Utils", I have a tiny tiny routine called rsort which is simply def rsort(l): "Return a list, sorted" l.sort() return l So the example above could then just be: <tr tal:repeat="obj python: here.objectValues().rsort()"> -- Joel BURTON | joel@joelburton.com | joelburton.com | aim: wjoelburton Independent Knowledge Management Consultant
