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.
John, please, *always* provide tracebacks instead of saying things like "it doesn't".
Any ideas?
Without a traceback, everything I say below is guesswork.
I'm assuming the above line comes from a page template. You neglected to mention what the calling DTML looks like, but I *guess* that it was something like this: <dtml-var "some_template(parm='ABC')"> yes? no?
This is what I have:- <dtml-var expr="testlist(parm='myobjectname')"> I wish to get 'myobjectname' into this line in 'testlist' which is marked with ********* python:here.parse_file(file=context.******,sepr=',',clone=1)"> There must be a simple way of doing this, but I haven't come across an example of it and I've spent most of the day on it.
I am pretty sure that your problem is with the expression context.options['parm']. Why do I say this? Hint 1: Look at that expression from left to right. Hint 2: Think about what "context.options" means.
In general, if you have not, you really should read the whole of http://www.plope.com/Books/2_7Edition/BasicScripting.stx and http://www.plope.com/Books/2_7Edition/ScriptingZope.stx ... not just once but several times :-)
There is too much to read and understand. Much of it only ever makes any sense in retrospect. Manuals are not a very useful way of learning how to do something
Taken together, they answer all "how to call X from Y" questions.
I'm sure they do, if you can make any sense of it.
