如何根据django模板中不同的提交按钮在更新视图中自定义成功url？

<form method="post" action="{% url 'update_view' %}">
    {% csrf_token %}
    <input type="submit" name="button1" value="按钮1">
    <input type="submit" name="button2" value="按钮2">
</form>

from django.shortcuts import redirect

def update_view(request):
    if request.method == 'POST':
        if 'button1' in request.POST:
            # 处理按钮1的逻辑
            return redirect('success_url_1')  # 自定义成功URL1
        elif 'button2' in request.POST:
            # 处理按钮2的逻辑
            return redirect('success_url_2')  # 自定义成功URL2
    return render(request, 'update_template.html')

from django.urls import path

urlpatterns = [
    path('update/', update_view, name='update_view'),
    path('success-url1/', success_url_1_view, name='success_url_1'),
    path('success-url2/', success_url_2_view, name='success_url_2'),
]
