The method that contains your code must have at least the first parameter 'self'::
def pdfwrite(self): R = self.REQUEST.RESPONSE R.setHeader('content-type', 'application/rtf') R.setHeader('content-length', str(len(data))) R.write(data)
It's a way of getting access to context.
OK, thanks. But how can I pass the self parameter using the dtml-call tag? <dtml-call "pdfwrite(self)"> is correct? Because I'm using this and works fine.
It's Python magic. When you call a function/method on an object, the object is provided as the first parameter of the method. This is implicit, I believe, in DTML calls, either expression or name. It's explicit in TALES and Python::
context/pdfwrite context.pdfwrite()
It's different than many other languages, but it turns out to be pretty useful.
