I'm using the Photo product, instances of which I can call, with arguments, like this:
<dtml-var "my_photo(display='thumbnail')">
However, I can't work out how to pass arguments to each sequence item when iterating over a sequence.
For example, I've tried:
<dtml-in objectValues(['Photo'])"> <dtml-var "_['sequence-item'](display='thumbnail')"> </dtml-in>
(..not that I expect that to work :)
And I get
Error Type: TypeError Error Value: call of non-function (type string)
I've tried various combinations of ways of calling the sequence-item, but they all return the same error. Could anyone suggest how I should do this? Thanks in advance...
You were very close -- the trick here is that 'objectValues' returns real objects, not IDs. Try this (untested):: <dtml-in "objectValues( [ 'Photo' ] )"> <dtml-let photo=sequence-item> <!-- alias so we can use in expr! --> <dtml-var "photo( display='thumbnail' )"> </dtml-let> </dtml-in> Tres. -- =============================================================== Tres Seaver tseaver@digicool.com Digital Creations "Zope Dealers" http://www.zope.org
