For a template, you could write a context processor that puts the computed value into the template's context each time. For a view, you could write a method on the model that accepts the "user" object and returns the correct value. It doesn't even have to be a method on the model -- it could just be a separate helper function. The point is that you're going to have to pass in the user object each time anyway, since there's no way to magically read that out of thin air.
