如何在django，python上使用'redirect‘和'message’

from django.shortcuts import redirect

def my_view(request):
    # 重定向到另一个URL
    return redirect('/another-url/')

MIDDLEWARE = [
    ...
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    ...
]

from django.contrib import messages

def my_view(request):
    # 添加消息提示
    messages.success(request, '操作成功！')
    return redirect('/another-url/')

{% if messages %}
    <ul class="messages">
        {% for message in messages %}
            <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>
        {% endfor %}
    </ul>
{% endif %}
