How to return QuerySet from View?

Question

Django

I have such a function for selecting several objects, which I call from ajax:

def get_elements(request):
    """View function for getting all existed elements (lines) of the scheme of the specific plan"""

    data = request.GET
    plan = get_object_or_404(Plan, pk=data.get("plan"))

    v = Element.objects.filter(plan=plan)

    return ...

v - this is a set of objects, not a single object
What should I write in return to return this set to my ajax? What I just did not write gives errors ...
