Answer 1

Maybe django-filter would help simplify the solutions others have given?

Something like:

class BookFilter(django_filters.FilterSet):
    class Meta:
        model = Book
        fields = ['author__age', 'author__gender', ...]

Then the view looks like:

def book_list(request):
    f = BookFilter(request.GET, queryset=Book.objects.all())
    return render_to_response('my_app/template.html', {'filter': f})
