[Zope] dictionary from sequence-item

[Alric Aneron]

Thanks,
I tried your suggestion Jonathan and I get this:
Error Type: AttributeError
       Error Value: has_key
Thanks anyway.
I never used ZPT, I'm not sure how to approach it from that angle...
would it be easy to do?  (You mean tal and metal right?)


Anyone have any other suggestions?
Thanks

   <dtml-let  aDict="_['sequence-item']">
      <dtml-if  "aDict.has_key('titled')">
             do  something here
  
  
 But this is still pretty ugly.  Another  approach would be to clean up the data in your list/dicts within the python  script, before you get to the dtml method.

   Subject: [Zope] dictionary from    sequence-item
   

Hello,
I am looping through a list of dictionary objects    using <dtml-in...
and within the dtml-in body I have:
<dtml-var    "_.getitem('sequence-item')['titled']" missing="none">
Some of the    dictionaries in the list don't have 'titled' key so it should replace it with    the word "none", but it gives me an error
Error Type:    KeyError
Error Value: 'titled'
I don't    understand.  Another option is that I can use <dtml-if    "_.getitem('sequence-item').has_key('titled')"> but it doesn't work, says    has_key is an unknown attribute.  This is the stupidest thing ever! it's    a dictionary object!
I try to typecast it using the    dict(_.getitem('sequence-item')).has_key('titled') it gives me an error saying    it can't typecast, but I am 100% sure it's a dictionary object because I can    access it easily _.getitem('sequence-item')['titled'] for those that have that    key.

Any idea how I can check if the titled key is in the dictionary    for the current list item?

Thanks in advance guys!
