Or, you can create a IResource wrapper that is used like this from
return (IResource, RememberWrapper(resource, user), lambda:None)
and looks like this (untested):
__implements__ = inevow.IResource,
def __init__(self, resource, user):
self.resource = resource
self.user = user
def locateChild(self, ctx, segments):
return self.resource, segments
def renderHTTP(self, ctx):
This avoids setting attributes on the resource which means you can reuse
a single *real* resource object if that makes sense to your application.
Hope this helps.
