Hello,

I have a DTML method that iterates over a list built by a Python script with the <dtml-in> tag. I want to be able to sort the list (with the attribute sort=sortColumn in the dtml-in tag). I have a few questions on this topic:

1) I assume that the dtml-in tag does not know how to sort a list of dictionaries having the same keys. It only knows how to sort Python class instances. Is it correct?

2) If I have to store Python class instances in my list, what feature must the class have? Does it have to inherit from Acquisition.Implicit, and / or Record.Record?

3) Do I miss something else on this topic?

Thanks for your help, Robert

From what I know, DTML in happyly sorts on lists of dictionaries. If you are using a python script to generate the list, you can easy do the sorting there also. See http://zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixB.stx/view module "sequence" You dont have to import it into python script, its already available. Just use it like this: return sequence.sort(yoursequence,[('key','cmp','asc'),('otherkey','cmp','asc')]) see the documentation for hints on sorting. There are a lot of options. This also helps when you finally skip DTML and use ZPT. Regards Tino
