Not at all. You could either have tried
it out ;) Or looked at the DTML documentation
in the Zope book *wink* ;)
<dtml-var expr="somemethod(parm1=value1,parm2=value2)">
Be warned: this is likely to cause loss of the namespace.
Do not forget to pass the two positional arguments (usually
as "None, _"). They are essential.
For more details, read "Calling DTML Objects" of
<http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>
That looks useful.
Is there also something which explains how to call ZPTs from a DTML
object?
I'm unable to pick up a passed parameter.
This is what I've conjured up:-
python:here.lib.parse_file(file=context.options['parm'],sepr=',',clone=1)">
hoping that "options['parm']" would get resolved as "ABC" but it
doesn't.
Any ideas?
When you call a ZPT like::
context.somePT(dog="beagle")
you can get to it in the template like::
options/dog
or::
python:options.dog
or::
python:getattr(options,'dog')
or maybe even::
python:options['dog']
Note that in the last two, I didn't need to know the name of the
parameter at coding time, but could find it at runtime. If I have::
tal:define="att string:dog"
then I can do::
python:getattr(options,att)
The 'options' name is not contained in context. It is it's own
first-class namespace.
If 'parse_file' above is a ZPT, you can ask for options/file,
options/sepr, and options/clone.
