RE: [Zope] How to list objects across different containers in Zop e's tree?

17 Jan 2001

      Right off the top of my head, since the sections are folder objects you
could simply dtml-in through the folders and then inbed another dtml-in.

Example (nothing fancy). 

I did not include any date range stuff, but you can probably figure that out
on your own. It may be better to include a 'section' property in your zClass
and then just search your Catalog (see catalog example below for an UNTESTED
example).

<dtml-in "objectValues(['Folder'])">
  <dtml-var name_or_id><br>
  <!-- now use the folder id to move into the correct namespace -->
   <dtml-with id>
     <!-- news stories here -->
       <dtml-in "objectValues(['newItems'])">
           <dtml-var headline><br>
           <dtml-var summary><br>
       </dtml-in>
         <br>
   </dtml-with>
   <br>
</dtml-in>

Catalog example

<dtml-in "objectValues(['Folder'])">
  <dtml-var name_or_id><br>

   <dtml-in "Catalog( { 'meta_type' : 'newsItem', 
                                'section' :  id,
                                'goLiveDate' : [ 2000/27/12 , 2001/05/01], 
                                'goLiveDate_usage' : 'range:min:max' } )"> 
           <dtml-var headline><br>
           <dtml-var summary><br>
  </dtml-in> 
   <br>
</dtml-in>

Thanks for the tip, James. It seems a clever approach although I must
keep it for the time being.
Anyway if that were the case, the question could be this one:
How can I list all the headlines and summaries for all the news appeared
for sports, locals and politics sections (in example) from December
27th,2000 and January 5th, 2001 ?
Greetings,

Ausum,
It may be time to re-think your site structure. I have a news type site
as
...
well and here is how I handle it (my way... not saying it is by any
means
the best or right way).
Instead of storing your news items in a series of folderish objects,
maybe
create folders for each section and then create a news item ZClass with
the
article date or goLiveDate as the ID.
zopesite:8080/sports/2000.10.17/newsobjectid_htm
Then do some dtml to pull out the ones you want on the main
"sport/thislist_htm" page.
Better yet use ZCatalog to search for the range of news items you want
to
appear in the list.
Hope this helps!!
