You could always do something like:
{{for i in range(len(all_items)):}}
{{=A(all_items.render(i, fields=db.t_stores.owner_id).owner_id,
_href=URL('default', 'stores', args=all_items[i].owner_id))}}
{{pass}}
Note, you don't have to specify the "fields" argument to .render(), but if
you only need one field rendered, that will be more efficient, as it won't
bother rendering the other fields.
