I want to list the content of some field of various Archetypes objects in a Topic object. Anyone could tell me how to access the fields from topic_view.pt page template for instance? I have already managed to access them from a custom view template, but since I'm not a programmer, I could't figure out yet how it works from another places.

It's pretty easy once you remember (or figure out) that the information you want from the object is likely NOT being stored in the portal_catalog as metadata. So, here's all you do to add another TD to the table and display an AT field called "teaser"... 1. get the topic_view.pt and hit customize 2. find the line just inside the <tbody> tag where it says <metal:block tal:repeat="match batch"> info: That's the start of the part that grabs info from your AT (and any other matching objects). But all it grabs is the metadata from the portal_catalog, and not your interesting field. You need to tell it how to find info from your AT object by using getObject. 3. So add a line like this inside the block <span tal:define="matchobj match/getObject"> and add a matching </span> just before the close of that </metal:block> 4. To get your "teaser", add this line right after the one calling Description: <td tal:content="matchobj/teaser | nothing">Teaser</td> That will grab your teaser from your object. If there's no "teaser" field (as in some non-AT object), it will return nothing, but not an error. Alternatively, you could replace "nothing" with " string:no teaser ". 5. Don't forget to add a matching teaser TH up in the top of the table so that people know what they're looking at: <th> <tal:block i18n:translate="">Teaser</tal:block> </th> Longer term, if this might be a performance barrier, get the portal_catalog metadata to pick up whatever AT fields that you'll need in your Topics. Good luck. =Paul
