我试图使用金字塔在Sprox中构建最简单的形式。
# 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>
当我在浏览器中导航到该视图时，

最佳答案
我不知道您真正的问题是什么，但是我召集了一个小样来演示如何在金字塔下设置Sprox。这有些痛苦，并且使用了一些我认为已经过时的习惯用法，包括要求Paste，SQLAlchemy
如果我不得不猜测的话，您并没有将中间件添加到您的应用程序中。
app = tw.api.make_middleware(
app,
{
'toscawidgets.framework' : 'wsgi',
'toscawidgets.middleware.inject_resources' : True,
},
stack_registry=True,
)
