I'm using DocumentTemplate from Python (not in Zope) and I want to use a custom format 'javascript_quote' that I've written. In my DTML file I have: <dtml-var name="name" fmt="javascript_quote"> and in the Python code I have def javascript_quote(s): .... template = DocumentTemplate.HTMLFile( 'page.dtml', {'javascript_quote': javascript_quote} ) print template(None, {'data': data}) But it complains that not everything was converted, presumably because it is trying to interpret the fmt="javascript_quote" as a C-style format. How do I get it to use my function? Hamish Lawson ____________________________________________________________ Do You Yahoo!?
