Django - Mixin with TemplateView

Question

I am trying to do something like the following to work, but I keep receiving the error 'RegionsView' object has no attribute 'method'. What am I doing wrong? Thanks

#views.py

class _LanguageMixin(object):

    def dispatch(self, request, *args, **kwargs):
        self.langcode = kwargs.pop("langcode")
        self.language = get_object_or_404(Language, pk=self.langcode)
        return super(_LanguageMixin, self).dispatch(self, request, *args, **kwargs)

    def get_context_data(self, **kwargs):
        context = super(_LanguageMixin, self).get_context_data(self, **kwargs)
        context.update({"language": self.language,
                        "languages": Language.objects.values_list('code',
                                                                  flat=True)})
        return context


class RegionsView(_LanguageMixin, TemplateView):
    template_name = "regions.html"

    def get_context_data(self, **kwargs):
        context = super(RegionsView, self).get_context_data(self, **kwargs)

        regions = #......

        context.update({"regions": regions})
        return context


#urls.py

url(r'^(?P<langcode>[a-zA-Z-]+)/regions/$', RegionsView.as_view(), name='regions')

This line produces the error:`return super(_LanguageMixin, self).dispatch(self, request, *args, **kwargs)` — Mihai Zamfir, May 19 '14 at 13:19

return super(_LanguageMixin, self).dispatch(request, *args, **kwargs)

instead of

return super(_LanguageMixin, self).dispatch(self, request, *args, **kwargs)

(request.method is used in the dispatch function, but you use self object)

seems it fiex my error, But now I got `get_context_data() takes exactly 1 argument (2 given)` at this line: `context = super(ThemesView, self).get_context_data(self, **kwargs)` – Mihai Zamfir May 19 '14 at 13:23

``get_context_data`` must be used without ``self`` also – erthalion May 19 '14 at 13:23
yep, removing `self` in both the calls seems to work. Thanks! – Mihai Zamfir May 19 '14 at 13:25
