python - How do I pass template context information when using HttpResponseRedirect in Django?

Question

I have a form that redirects to the same page after a user enters information (so that they can continue entering information). If the form submission is successful, I'm returning

HttpResponseRedirect(request.path)

which works fine. However, I'd also like to display some messages to the user in this case (e.g., "Your data has been saved" at the top of the screen). If I weren't redirecting, I'd just return these messages in the context dictionary. With the redirect, however, I can't do this.

So how can I pass template context information when using HttpResponseRedirect?

What I'm trying to do seems like it would be incredibly common, so please excuse me if I'm missing something obvious.

For the sake of completion and future reference, you can now use the messages framework. After you install it:

views.py

from django.contrib import messages

def view(request):
  # your code
  messages.success(request, "Your data has been saved!")
  HttpResponseRedirect(request.path)

template.html

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