Try this: (!! be careful with excessive recurssion !!) print context.index_html(context,ERQUEST) OK, I tried that and got a name error on REQUEST, so I did this instead: print context.index_html(context, context.REQUEST)
ok. typo by me.
But that gave me an error like:
Error Type: TypeError Error Value: no arguments expected
Is it a DTML Method or DTML Document? I'm positivly sure that you have to pass something. But it could be awefully complicated what and when and why. Experts!? Help. I was working on a Python Script, and I remember that somedtmlobject() never worked but finally did later when I passed context and REQUEST. In mycase it was just a call, and I wasn't interested in what it returned.
So I tried not supplying any arguments... context.index_html(), and got the 'excessive recursion error'.
'excessive recursion error' is good. That means that your Python Script "DTMLcalling" works. It's just a matter of if it returns HTML or text. The excessive recurssion is because you're calling an object that calls the script. Do it with context.bloodyjavascript() or something instead. Peter
Any clues?
Thanks

I have a ZClass (testclass) which subclasses DTMLDocument, and within this zclass, I have a script (python) called index_html. Obviously, this script is called each time an instance of testclass is requested. Based on the presence of a query string, I want to either return the document_src (although with a few modifications), or simply return the rendered instance... by this, I mean have all the dtml tags that are in the instance evaluated. So, my question is, how do I make Zope evaluate the dtml tags?
Here is what I have so far in my script:
------------ if context.REQUEST.QUERY_STRING == 'editor': print context.raw else: print context
return printed ------------
The 'else' statement simply gives me things like,
<dtml-var standard_html_header>
I also tried 'else: render(context)', which was simply a guess on my part, but I get a Zope error as follows:
Error Type: AttributeError Error Value: validate
Can anyone enlighten me?
Cheers
tim
