Usage in Views

You can retrieve a Variable instance from HttpRequest instance if you add PersistentSettingsMiddleware¹ to middlewares. HttpRequest instances are injected in views by Django. If you use a function-based view:

def foo_view(request, *args, **kwargs):
    # `request` is `HttpRequest` instance
    bar = request.persistent_settings["bar"]
    # ...

If you use a class-based view:

class FooView(TemplateView):
    template_name = "foo.html"

    # for example, let's assume we need a Variable inside foo.html
    def get_context_data(self, **kwargs):
        # you can get HttpRequest instance with self.request
        kwargs["bar"] = self.request.persistent_settings["bar"]
        return super().get_context_data(**kwargs)

Tip

This was only an example. You can already use custom template tags to get Variables in templates, discussed in the next section.
