I need to write a dtml method which calls an external method, which returns a dictionary, and have the dtml method lookup and use keys and values from the dictionary. Is this even possible? If so how? I am completely stuck! I would really appreciate any help with this. Thanks.
Just off the top of my head (untested!) the following sort of thing should work:
def AnExtMeth(): return {1: 'one', 2: 'two', 3: 'three'}
<dtml-let dict="AnExtMeth()"> <dtml-in expr="dict.items()"> &dtml-sequence-key; &dtml-sequence-item; </dtml-in> 1: <dtml-var expr="dict[1]"> </dtml-let>
or <dtml-call expr="REQUEST.set('dict', AnExtMeth())"> to make the dictionary generally available.
Or for even *more* twisted fun: <dtml-call expr="REQUEST.other.update( AnExMeth() )"> sucks each key/value pair into the "default" namespace.
