Answer 1

You can try to split the values by a comma:

def result_test(request):
    selected = request.POST.get('selectedTests')
    if selected is not None:
        try:
            booktests = BookTest.objects.filter(test__in=selected.split(','))
        except ValueError:
            # … (1)
        else:
            return render(request, 'posts/result.html',{'var1':booktest})
    else:
        # … (2)

You will need to return some HTTP result for (1) (when the format is not respected), and (2) when the request does not contain a selectedTests value in the first place.

That being said, it might be better to just define the checkboxes as:

<input type="checkbox" name="" /> option 1
<input type="checkbox" name="" /> option 2

such that you do not have to rely on JavaScript to inject the selected values in the hidden input element.
