Python Django消息框架未在模板中显示消息

这是我的设置文件

STATICFILES_FINDERS = (
    'django.contrib.staticfiles.finders.FileSystemFinder',
    'django.contrib.staticfiles.finders.AppDirectoriesFinder',
    'django.contrib.staticfiles.finders.DefaultStorageFinder',
)
TEMPLATE_CONTEXT_PROCESSORS = (
       "django.core.context_processors.request",
       "django.core.context_processors.media",
)
# Make this unique, and don't share it with anybody.
SECRET_KEY = '*******************************'
# List of callables that know how to import templates from various sources.
TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',
#     'django.template.loaders.eggs.Loader',
)
MIDDLEWARE_CLASSES = (

   'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    # 'django.middleware.clickjacking.XFrameOptionsMiddleware',
)

在模板中，我添加了以下代码来显示消息

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

我已经在视图中从django.contrib导入消息导入了

我不知道我到底做错了什么。我无法在登录页面中获得任何消息

请帮帮我
 尝试将
django.contrib.messages.context\u processors.messages
添加到模板上下文处理器列表中。
将上下文处理器更改为：

TEMPLATE_CONTEXT_PROCESSORS = (
   "django.core.context_processors.request",
   "django.core.context_processors.media",
   "django.contrib.messages.context_processors.messages"
)

这样，django将把所有消息放到用于呈现模板的上下文中，因此您可以访问模板中的
消息

顺便说一句，你永远不应该公开发布你的
密钥。从来没有

很好，谢谢，但我已经添加了中间件，为什么它不起作用，这不是中间件，这是上下文处理器。中间件用于修改传入的请求或呈现的响应，而上下文处理器用于修改从视图发送到模板的数据。
