Django:我如何在下拉列表中选择并重定向到另一个页面？

<form method="POST" action="{% url 'redirect_view' %}">
  {% csrf_token %}
  <select name="page">
    <option value="page1">页面1</option>
    <option value="page2">页面2</option>
    <option value="page3">页面3</option>
  </select>
  <button type="submit">提交</button>
</form>

from django.shortcuts import redirect

def redirect_view(request):
    if request.method == 'POST':
        page = request.POST.get('page')
        if page == 'page1':
            return redirect('page1_view')
        elif page == 'page2':
            return redirect('page2_view')
        elif page == 'page3':
            return redirect('page3_view')
    return render(request, 'form.html')
