How do I access a model outside of a view in Django?

I am creating a database site and one of the desired features is to have a button in the navbar that will that the user to a random object in a model. The Django Cookbook gives an example of a random function for a model, which I implemented.

However, I cannot seem to call this function from the navbar, since the navbar is in a separate html file that is included above the {% block content %}, which allows it to appear on every page of the site. However, this means it never sees the model object itself, so I cannot access the function with {{object.get_random}} in the navbar.

One idea I had was to use a link in the navbar like this

<a href="{% url 'roma:category_list.object.get_random.get_absolute_url' %}">Random Category</a>

where category_list is the view that has the model passed to it. From there I hoped to grab an object from the model, then the get_random function, and finally the url from the object returned from the get_random function. This obviously does not work. Is there a solution that will allow me to access the function in the navbar html?

Instead of doing the randomization when rendering the template, I would make a link to a dedicated view with a url like "/random". When that url is called, the view can do the randomization and redirect you to the random model.
