[Zope] Calling dynamic zsql method from zpt?

[Nick Bower]

I've searched everywhere for a seamingly obvious thing to have in the
documentation - how to call a dynamic zsql method from a zope page
template using arguments.

What I need is something like this:

<div tal:define="sqlRows
nocall:here/ZSQLTerritoryList(parent_id=parent_id)">
  <select name="country_list">
  <option value="">ANY</option>
  <option tal:repeat="sqlRow sqlRows" ...
  etc...

but obviously the first line of code doesn't work.  How else are
variables passed do zsql methods from page templates?

Thanks, Nick
