def add_name(request):
if request.method == 'POST':
    form = TestForm(request.POST)
    name1 = request.POST.get('name_test')

    print(name1)
    if form.is_valid():
        form.instance.name = name1
        form.save()
        return redirect('test_name')
else:
    form = TestForm()

return render(request, 'test/add.html', {'form': form})
