Views
=====
A view is a callable which is invoked when a request enters your
application. :mod:`repoze.bfg's` primary job is to find and call a
view when a request reaches it. The view's return value must
implement the WebOb Response object interface.
Defining a View as a Function
-----------------------------
The easiest way to define a view is to create a function that accepts
two arguments: *context*, and *request*. For example, this is a hello
world view implemented as a function::
def hello_world(context, request):
from webob import Response
return Response('Hello world!')
View Arguments
--------------
context
An instance of a model found via graph traversal.
request
A WebOb request object representing the current request.
