Question

I’m trying to use the message middleware in Django, but the view does not render it at all. What I have:

views.py

messages.success(request, 'Test message.')
return render_to_response('base.html') 

template.html

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

When I do this in the view:

for message in messages.get_messages(request):
    print message

it prints a message for every time I called the view since i last used this function, so it definitely saves the messages somewhere. It is just not sent to the template.

Additional info:

• Django version = (1, 2, 3, ‘final’, 0)
• I added ‘django.contrib.messages.context_processors.messages’ to TEMPLATE_CONTEXT_PROCESSORS. Note: I had no TEMPLATE_CONTEXT_PROCESSORS even though it’s supposed to be there since Django 1.2 so I just added it. I guess that it might not be working properly and that this might be the problem, but I don’t know how to check if it is properly configured.
• I followed https://docs.djangoproject.com/en/dev/ref/contrib/messages/ to set it up.

You need to render the template with a RequestContext instead of just Context (which render_to_response uses by default) to make your template context processors available in the template. Check out the optional arguments section of the render_to_response docs then change:

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