Джанго - Как вывести содержимое функции в шаблон

Непонимаю как вывести содержимое функций в шаблон - функции перехода от первого поста к слудующему и обратно. Заранее спасибо за ответ! Есть модель категории и их slug и есть модель посты связвные с категорией ForeignKey со slug.

def get_next_post(post_slug, category_slug):  
    found = post.objects.first(cat__slug=category_slug, slug__gt=post_slug).order_by("slug")
    if not found:
        found = post.objects.first(cat__slug_gt=category_slug).order_by("slug")
    return found


def get_previous_post(post_slug, category_slug):  
    found = post.objects.last(cat__slug=category_slug, slug__lt=post_slug).order_by("slug")
    if not found:  
        found = post.objects.last(cat__slug_lt=category_slug).order_by("slug")
    return found


def content_post(request, category_slug, post_slug):
    found_post = get_object_or_404(post, slug=post_slug, cat__slug=category_slug)
    next = get_next_post(post_slug, category_slug)
    previous = get_previous_post(post_slug, category_slug)
    if next:
        next_url = next.get_absolute_url()
        next_title = "next"
    else:
        next_url = reverse("homepage")
        next_title = "home"

    if previous:
        previous_url = previous.get_absolute_url()
        previous_title = "previous"
    else:
        previous_url = reverse("homepage")
        previous_title = "home"

    return render(
        request, 
        "content/post.html", 
        {
            "post": found_episode,
            "next_url": next_url,
            "next_title": next_title,
            "previous_url": previous_url,
            "previous_title": previous_title,
        },
    )
