Re: [Zope] Variable substitution of <dtml-in> Attributes

Hi all,

This doesn't appear to be possible but I'm just confirming. I have this line of code:

<dtml-in expr="PARENTS[0].objectValues('Folder')" sort=id>

I'd like to be able to substitute the Attributes as a string. For example a dtml method called sort_order may contain the string:

reverse sort=id

Then I would substitute that in at runtime. It might look something like this:

<dtml-in expr="PARENTS[0].objectValues('Folder')" &dtml-sort_order;>

However this and similar attempts gives me a Document Template Parse Error.

It's possible, IIRC you have to use sort_expr instead of sort. See the source-code of the ZMI, it's used there (for dynamic sorting of the folder contents) cheers, oliver
