Django 1.2中的消息框架问题

Question

我正在运行Django 1.2 beta并试用新功能:消息框架.

http://docs.djangoproject.com/en/dev/ref/contrib/messages/

一切似乎都有效,但当我尝试输出消息时,我什么也得不到.似乎messages变量是空的.我仔细检查了所有设置,它们似乎就像在手册中一样.可能有什么不对？

settings.py

MIDDLEWARE_CLASSES = (
    'django.middleware.common.CommonMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware', #send messages to users
    'django.middleware.locale.LocaleMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',

    #debug tool
    'debug_toolbar.middleware.DebugToolbarMiddleware',
)

TEMPLATE_CONTEXT_PROCESSORS = (
    'django.contrib.messages.context_processors.messages', #send messages to users
    'django.core.context_processors.auth',
)

#Store messages in sessions
MESSAGE_STORAGE = 'django.contrib.messages.storage.session.SessionStorage';

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    #'django.contrib.sites',
    'django.contrib.admin',
    'django.contrib.messages', 
    'debug_toolbar',

    #my apps
    #...
)

views.py

def myview(request):

    from django.contrib import messages

    messages.error(request, 'error test');   
    messages.success(request, 'success test');   

    return render_to_response('mytemplate.html', locals()); 

mytemplate.html

{% for message in messages %}
        {{ message }}<br />
{% endfor %}

在模板中没有输出.

您需要RequestContext在通话中使用render_to_response.

return render_to_response('mytemplate.html', locals(),
                          context_instance=RequestContext(request))
