Add renderer in @view_config from configuration?

Question

How do I supply a configured value to a @view_config-decorated function or class?

E.g.

@view_config(route_name='example', renderer=some_config['template.name'])
class MyClass(BaseView):
    ...

Or

@view_defaults(route_name='example', renderer=some_config['template.name2'])
class MyClass2(BaseView):
    ...

Or

@view_config(route_name='example', renderer=some_config['template.name3'])
def method3(request):
    ...

It's very hard to know where to start, as I'm trying to edit a pyramid plugin, which pulls together its config in an includeme function, so it doesn't have anything obvious that I can include, and it's hard to know what's available to the @view_config decorator.

You can add views using declarative configuration (what you are doing now using @view_config or alternatively using imperative configuration by calling config.add_view() method.

In this case, as you need to access the Pyramid registry and settings file, it is easier to do adding the views imperatively.

In your __init__.py you can do:

  settings = config.registry.settings
  # You need to call config.add_route("foobar") to map view to URL also

  config.add_view('views.MyClass', route_name="foobar", renderer=settings['template.name3'])

Then in your views.py:

  class MyClass(BaseView):
       pass    

@view_config() and add_view() arguments are equal.

I thin kyou can also mix view_config and add_view() arguments for the same view, but I am not sure aobut this. Hope this helps.
