Please stop me going mad.
I created two python method. The first , called 'know_nothing' takes no parameters but returns the string "I know nothing", the second, called 'timesit" takes two parameters, multiplies them and returns the result. When I come to use them from within a DTML document why do I have to say <dtml-var "timesit(1,2)"> but <dtml-var know_nothing>
I assume the top one is short for <dtml-var expr="timesit(1,2)"> whereas the second is short for <dtml-var name=know_nothing> (or even <dtml-var name="know_nothing"> since that seems to work as well)
(am I right ?)
and I think I understand that the name attribute is actually a function call with no parameters - right ?
but why does <dtml-var expr="know_nothing" not return anything to the calling object ?
Just when you think you are getting the hang of it :-)
I *think* that <dtml-var know_nothing> is actually equivalent to <dtml-var expr="know_nothing()"> however I can't test this at the moment so I may be completely wrong :-). /Matt
