I've tried to build the simplest possible form in Sprox using pyramid.
# model.py
class Allocation:
# some fields ...
class SproxForm(AddRecordForm):
__model__ = Allocation
sprox_form = SproxForm(DBSession)
# views.py
@view_config(route_name='sprox_add', renderer='templates/sprox.pt')
def sprox_form_add(request):
return {'form':sprox_form,'form_input':{}}
<!-- sprox.pt -->
<html>
<body>
<div tal:content="structure form(form_input)"/>
</body>
</html>
When I navigate to that view in the browser, I get
Traceback (most recent call last):

I have no idea what your real problem is, but I threw together a little demo to demonstrate how to setup Sprox under Pyramid. It was somewhat painful and uses some idioms that I consider pretty outdated, including requiring Paste, SQLAlchemy < 0.8, Genshi, and ToscaWidgets < 2.0. Hope this helps.
If I had to guess, you aren't adding the middleware to your app.
app = tw.api.make_middleware(
app,
{
'toscawidgets.framework' : 'wsgi',
'toscawidgets.middleware.inject_resources' : True,
},
stack_registry=True,
)
