AWS dev服务器Django-3.1中没有出现在admin中的消息

Question

上下文：Django 3.1app部署到一个具有terraform的AWS中。我还没有设置我的生产设置，这是我的开发服务器。

我用的是https://github.com/adamchainz/apig-wsgi

我注意到来自django.contrib.messages的消息在试图通过djangorestframework-api-key通过管理获取api密钥时不会出现。它位于lambda上，意味着我无法以编程方式访问lambda来创建api密钥。

注意到：django-debug-toolbar也不起作用，而且很安静，所以我很怀疑我的context_processors设置是关闭的，所以我没有messages或DEBUG变量，但是在我的设置中找不到问题？？下面是我的代码，没有调试工具栏设置。

    install_secrets()

    if _real_handler is None:
        print('No Cache, getting secrets.')
        install_secrets()

        application = get_wsgi_application()
        _real_handler = make_lambda_handler(application)

    return _real_handler(event, context)

默认的管理模板admin/base.html，在这里我期望消息会出现(它只是循环遍历messages对象，不需要任何JS或CSS出现)：https://github.com/django/django/blob/2d8232fa716f5fe46eec9f35a0e90c2d0f126279/django/contrib/admin/templates/admin/base.html#L82

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

requirements.txt

Django>=3.1,<3.2
django-storages==1.11.1
apig-wsgi
psycopg2-binary
djangorestframework
djangorestframework-api-key==2.1.0

尝试：

• 尝试了硬重新加载F5，
• 尝试添加django调试工具栏和记录管理中消息中显示的像素键，但是没有工作，因为工具栏也没有显示(在上面的代码中没有显示)
• 尝试了在dev服务器上进行收集，
• 尝试检查用户会话并查看用户会话上的消息，其中有< code >H 231F 232

一位才华横溢的同事解决了这个问题。添加

MESSAGE_STORAGE = 'django.contrib.messages.storage.session.SessionStorage'

您的设置解决了这个问题。
