OK .. sorry for the hand-holding here, but the syntax of this doesn't make sense to me. If I try: _.sequence.sort(sequencename, 'lname', 'asc') where sequencename is a python script that returns a list of dictionaries and lname is the name of a key in those dictionaries that I wish to sort by. Then it doesn't barf, but it doesn't sort either. if I use: _.sequence.sort(sequencename, (('lname', 'asc'),)) Which is imitating the syntax from the Zope Book, then it barfs with: Attribute Error: 'None' has no object 'getitem' so ... I guess the question here is, What is the correct syntax to make this work? Thanks so much for your help, Rick Andreas Jung wrote:

Check sequence.sort(). Docs are in the API refs.

Is there a way to do a dynamic sort= on a dtml-in on a list of dictionaries?

like:

<dtml-call "REQUEST.set('sortby', 'firstname')">

<dtml-in "queryname_py" mapped sort=_['sortby']> etc...

I've tried _['sortby'], _[sortby], "_['sortby']", and "_[sortby]" and I always get an error. Is there an easy way to do this?

Thanks,

Rick

That did it! Thank you! I have very few compelling reasons to change to ZPT at this point, and it would actually be a small disaster to attempt it. I have 6 very large reporting sites built entirely on DTML that have been running for over 2 years now that way. It would be a major undertaking to overhaul them to ZPT, not to mention the fact that there would be a learning curve while I was trying to figure out how to get all of what I had working to work with templates. The other issue is that neither myself, nor our web designer uses a GUI page builder. He hand codes everything right through the Zope interface, as do I. I've learned to keep the business logic well seperated from the design elements, so I really don't have a strong reason to jump, especially since I'm so comfortable with DTML.

According to the documentation* what you want is 'sort_expr='. I do however recommend you stop using DTML alltogether.
