Question

With function based Django view it was simple to switch between several different views based on a condition, e.g. something like:

def base_view(request):
    if some_condition():
        return foo_view(request)
    else:
        return bar_view(request)

I can’t find a simple way to do the same with the new class-based generic views. The only way I can think of is to redisrect, which I would like to avoid for various reasons:

def base_view(request):
    if some_condition():
        return redirect(reverse("name_of_url_to_class-based_view_foo"))
    else:
        return redirect("/url_to_class-based_view_bar/")

Any suggestions?

This is equivalent to your example with class based views.

class FooView(View):
    pass

class BarView(View):
    pass

class BaseView(View):
    # staticmethod to avoid adding 'self' to the arguments
    foo_view = staticmethod(FooView.as_view())
    bar_view = staticmethod(BarView.as_view())

    def dispatch(self, request, *args, **kwargs):
        if some_condition():
            return self.foo_view(request, *args, **kwargs)
        else:
            return self.bar_view(request, *args, **kwargs)
