斯洛伐克與金字塔 - 第2部分你好世界

我試圖用金字塔在Sprox建立最簡單的可能的形式。斯洛伐克與金字塔 - 第2部分你好世界

# 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>

當我導航到該視圖在瀏覽器中，我得到

又見http://stackoverflow.com/questions/14419400/the-hello-world-of-sprox-with-pyramid – pihentagy

我不知道你真正的問題是什麼，但我演示瞭如何在金字塔下設置Sprox。這有點痛苦，並使用了一些我認爲很過時的習語，包括需要粘貼，SQLAlchemy 0.8，Genshi和ToscaWidgets < 2.0。希望這可以幫助。

如果我不得不猜測，您並未將中間件添加到您的應用程序中。

app = tw.api.make_middleware(
    app, 
    { 
     'toscawidgets.framework' : 'wsgi', 
     'toscawidgets.middleware.inject_resources' : True, 
    }, 
    stack_registry=True, 
)

是的，你的猜測是正確的（再次）。感謝您將這個項目放在一起的努力。只需將'tw.api'替換爲'tw2.core'，它就可以與金字塔1.4和tw2一起使用。希望我可以更新您的演示到一個體面的配置。 – pihentagy

我肯定會接受一個拉取請求來改進它。 –
