[Answered ]-Django class based views example

Here’s a simple way to achieve what you want:

You first define the common logic, using the TemplateView generic view:

class MyBaseView(TemplateView):
    def dispatch(self, request, *args, **kwargs):
        # dispatch takes care of "reading" the parameters from the url
        self.language = get_object_or_404(Language, pk=kwargs.pop("langcode")) # I would use some kind of default value to prevent exception, but its up to your logic
        return TemplateView.dispatch(self, request, *args, **kwargs)

    def get_context_data(self, **kwargs):
        # get_context_data creates the context
        context = TemplateView.get_context_data(self, **kwargs)
        context.update({"language": self.language, 
                        "languages": Language.objects.values_list('code', flat=True)})

        return context

Then, you don’t even need an AboutView because all you want is to control the template_name, so in your urls.py:

# in urls,py you can just use this, instead of defining an AboutView, you pass the template_name you want to use, this is sufficient because TemplateView expects a template_name attribute
url('^(?P<langcode>[a-zA-Z]+)/about/$', MyBaseView.as_view(template_name="about.html"), name='about')

and finally, for the other view that uses region you can just inherit from the MyBaseView, and add the context you want:

class AboutViewWithRegion(MyBaseView):
    def get_context_data(self, **kwargs):
        context = MyBaseView.get_context_data(self, **kwargs)
        context.update({"region": <<your logic here>>})
        return context

Hope that helps!
