You can use django-flashcookie app http://bitbucket.org/offline/django-flashcookie/wiki/Home

it can send multiple messages and have unlimited types of messages. Lets say you want one message type for warning and one for error messages, you can write

def simple_action(request):
    ...
    request.flash['notice'] = 'Hello World'
    return HttpResponseRedirect("/")

or

def simple_action(request):
    ...
    request.flash['error'] = 'something wrong'
    return HttpResponseRedirect("/")

or

def simple_action(request):
    ...
    request.flash['notice'] = 'Hello World'
    request.flash['error'] = 'something wrong'
    return HttpResponseRedirect("/")

or even

def simple_action(request):
    ...
    request.flash['notice'] = 'Hello World'
    request.flash['notice'] = 'Hello World 2'
    request.flash['error'] = 'something wrong'
    request.flash['error'] = 'something wrong 2'
    return HttpResponseRedirect("/")

and then in you template show it with

{% for message in flash.notice %}
    {{ message }}
{% endfor }}

or

{% for message in flash.notice %}
    {{ message }}
{% endfor }}
{% for message in flash.error %}
    {{ message }}
{% endfor }}
