There's no simple way of constructing URLs to views on different skins

[Jan Wijbrand Kolman]

It is currently not possible to easily construct an URL to a view on a different skin/layer. E.g. when you want some view to construct an URL to some REST view.

[Jasper Spaans (jspaans)]

There is a hard way, inspired on http://jw.n--tree.net/irclogs/%23grok/%23grok.2008-03-27.log.html :

class ContentRESTLayer(grok.IRESTLayer):
    pass

class ContentRESTProtocol(grok.RESTProtocol):
    grok.layer(ContentRESTLayer)

# A REST handler is not a view; provide a dummy Container that is
# always published using a REST handler. This container can then be
# given its place in the urlspace.
# Note that the context which is probably needed is the __parent__ of
# the context of this container.

class ContentRESTView(grok.Container):
    def render(self):
        return "i don't exist"

from zope.app.publication.interfaces import IBeforeTraverseEvent
from zope.publisher.http import applySkin

@grok.subscribe(ContentRESTView, IBeforeTraverseEvent)
def ContentRESTViewHack(obj, event):
    applySkin(event.request, ContentRESTLayer, grok.IRESTSkinType)

class ContentRESTViewHandler(grok.REST):
    grok.context(ContentRESTView)
    grok.layer(ContentRESTLayer)

    def GET(self):
        context = self.context.__parent__
        return context.somemethod()

This looks like a problem that's very hard to solve generally.

Perhaps we want to provide specific solutions for particular cases.
