Proposal for a new decorator in pyramid or an extension

example.py

from pyramid_view_controller import view_controller

from ..models import Building, House, Factory, Skyscraper

class AbstractController(object):

    # will not become a view because the class has no @view_controller decorator
    @view_controller(name='view')
    def view(self):
        ...
        return response


# the view method in AbstractController will now become a view within
# BuildingController because it is decorated with @view_controller, but
# it will also inherit the predicates from the class @view_controller, so
# it will only be a view for Building resources.
@view_controller(context=Building)
class BuildingController(AbstractController):

    def __init__(self, request):
        self.request = request
        ...
        # do some setup for all methods

    def cleanup
        # do some cleanup for all methods

    # this method will be the view for Factory resources
    @view_controller(context=Factory)
    def view_factory(self):
        ...
        return response

    @view_controller(name='edit')
    def edit(self):
        ...
        return response

# here the view method overwrites the method from the base class and will
# be called for Skyscraper resources
@view_controller(context=Skyscraper)
class SkyscraperController(BuildingController):

    @view_controller()
    def view(self)
        ...
        return response
