在 django 中对搜索结果进行排序

Question

I'm have a django app with the following model.

class Posts(models.Model):
    post =  models.TextField(max_length=1500)
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    likes = models.ManyToManyField(User, related_name="post_likes")
    category = models.CharField(max_length=50, default=None)

To allow the users search for a particular blog and then display those objects I have the following view.

def index(request):
    if request.method == "GET":
        search = request.GET.get("input")
        posts = Posts.objects.filter(category__icontains=f"{search}")
    else:
        posts = Posts.objects.all()
    params = {'blog': posts} 
    return render(request, 'index.html', params)

In the above view, variable search contains what user has searched for, that I'm receiving through a form. But I also want to provide a sort functionality after user has searched for a blog. Like user searches for "recipes" , I need to show them all the search results and then let him sort them based on likes and recent etc. How do I do it since I'm losing search terms just after displaying the results.

I'm assuming the sort options are also part of the search form so you could also send the chosen sort option as a query parameter to the backend, just as you're doing with the search term:

sort = request.GET.get('sort')
# use the sort options to order your queryset as you desire
