I'm not sure whether I understand you correctly but here's a trick I
use.
class InlineWidget(Widget):
def __call__(self, obj):
return self.insert(obj)
book_catalog_form =
DataGrid(template="bookswap.templates.pagedatagrid",
fields=[
(_(u'info'),
InlineWidget(template='bookswap.templates.cat_bookinfo')),
(_(u'location'), 'location'),
(_(u'price'), 'price'),
(_(u'added'), book_added_pprinter),
('',
InlineWidget(template='bookswap.templates.cat_actions')),
])
Templates like .cat_actions has <?python item=widget_value?> on top and
the renders the item as they see fit.
