Django messaging framework messages not making it passed the redirect() -

i have "save" code sets success message using django messaging framework upon successful creation of record, redirect main 'application_update' view. i'm having trouble determining why these messages not making thru redirect. messaging seems work fine when doing "render_to_response", not when doing "redirect".

function snippet (if post) in views.py:

if ovrd_form.is_valid():     fields = {'application': ovrd_form.cleaned_data['application'],               'course': ovrd_form.cleaned_data['course'],               * other field/values *              }     try:         overrides = overrides(**fields)         overrides.save()         success_msg = 'override creation successful.'         create_message(request, success_msg, 'success')     except exception, exception:         return httpresponse('error: ' + str(exception))      return redirect('application_update', app_id=app_id) 

create_message() function:

from django.contrib import messages  def create_message(request, msg, msg_type):     """ build message & sets correct message.type """     if msg_type == 'error':         django.contrib.messages.error(request, msg)     elif msg_type == 'warning':         django.contrib.messages.warning(request, msg)     elif msg_type == 'success':         django.contrib.messages.success(request, msg)     elif msg_type == 'info':         django.contrib.messages.info(request, msg)     elif msg_type == 'debug':         django.contrib.messages.debug(request, msg) 

all templates inherit piece of code:

{% if messages %}     {% message in messages %}         {% comment %}force -danger if error type bootstrap css class{% endcomment %}         {% if message.tags == 'error' %}             <div class="alert alert-danger">         {% else %}             <div class="alert alert-{{ message.tags }}">         {% endif %}             <button type="button" class="close" data-dismiss="alert">&times;</button>             <span>{{ message }}</span>             </div>     {% endfor %} {% endif %} 

any appreciated.

we use function similar 1 below preserve messages after 1 or more redirects:

# preserve error messages... ie. if redirect results in # redirect.    django.contrib import messages  def preserve_error_messages( request ):     mstore = messages.get_messages( request )     m in mstore:         messages.add_message( request, m.level, m.message, extra_tags = m.extra_tags )     return 

edit: equivalent preventing messages being cleared/expired: https://docs.djangoproject.com/en/1.4/ref/contrib/messages/#expiration-of-messages
