URLs for blog posts can either be just their slug, or prefixed
        with a portion of the post's publish date, controlled by the
        setting ``BLOG_URLS_DATE_FORMAT``, which can contain the value
        ``year``, ``month``, or ``day``. Each of these maps to the name
        of the corresponding urlpattern, and if defined, we loop through
        each of these and build up the kwargs for the correct urlpattern.
        The order which we loop through them is important, since the
        order goes from least granular (just year) to most granular
        (year/month/day).
