I have implemented a simple ZSQL-Method (fetch) which takes one argument, a record number (nr). As far as I understand the ZSQL Manual, I should be able to write URL's of the form
fetch/nr/<number>/showit
where showit is a DTML-Document which can access the result of the fetch query. How do I access this result? I tried to use the column names (like <!--#var shortname-->, where shortname is a result column name), but Zope gave me a Key Error. What is the correct syntax to access the result columns of such a query?
I followup to my own posting, since I've found out something more: If I wrap the reference to 'shortname' into a <!--#with "PARENTS[1]"--> it works. Now this makes me ask a question about acquisition in Zope: I thought, Zope would search the object and all it's PARENT's to fetch objects. In the case of the above URL, the PARENTS seam to be somthing like [ <Zope-folder>,<Traverse-Wrapper>,<Result-record>,<Zope-folder ] (I realy don't know exactly, that's what I believe to be possible after inspecting the source). OTOH the Parent relationship (aq_parent) seams to be 'Zope-Folder->showit'. So am I right, that Zope only searches the aq_parent tree? No, I don't think so (at least when I see the recursive Acquisition thread, acquisition seams to work by PARENTS too) but this does look like it. Any comment from the Zope-Hackers? I'd really like to understand, what's going on here, especially since I'm just beginning with Zope. Thanks in advance for all your nice comments :-) Stefan.
