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

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 It was somewhat painful and uses some idioms that I consider pretty outdated, including requiring Paste, SQLAlchemy 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,
)

TemplateSyntaxError: Could not parse the remainder: '\u2018polls:detail\u2019' from '\u2018polls:detail\u2019'
How to resolve this ?
You are using left quote and right quote characters when quoting the view name; where you should be using single or double quotes.
Use either 'polls:details' or "polls:details"
pyramid/url.py seems to have a bug. Here is the code
import os
from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.response import Response
from pyramid.view import view_config
here = os.path.dirname(os.path.abspath(__file__))
#view_config(route_name='firstview',renderer='firstview.mako',request_method='GET')
def firstview(request):
return {'example':'text'}
#view_config(route_name='secondview',request_method='POST')
def secondview(request):
return Response('second view')
if __name__ == '__main__':
settings = {}
settings['mako.directories'] = os.path.join(here,'templates')
config = Configurator(settings=settings)
config.add_route('firstview','/firstview')
config.add_route('secondview','/secondview')
config.scan()
app = config.make_wsgi_app()
This is the template for firstview
# -*- coding: utf-8 -*-
<form name="example"
action="${request.route_url('secondview')}"
method="POST">
example
<textarea rows="4" cols="50" name="name">
</textarea><br>
<input type="submit" value="Submit">
</form>

TypeError: cannot concatenate 'str' and 'NoneType' objects
Since I added some lines for debugging purpose the line number will be different.
Anyway, I noticed that path returns None. In the code there is no handling of this case. I am new to the pyramid framework, I would appreciate your help. Thanks!
P.S.
Apparently this problem stems from url.py's function route_url. Specifically route.pregenerator(self, elements, kw) returns None and there is no handling of this case.
