With a Model

  6 class Text(models.Model):
  7     text = models.CharField(max_length=(10 ** 5))
  8     date = models.DateTimeField()

With a view

  7 def view_text(request, text_id):
  8     text = get_object_or_404(Text, text_id)
  9     return render_to_response(u""text.html"", {u""text"": text})

The Following is the output of the development server:

[11/Mar/2009 16:30:39] ""GET /text/5 HTTP/1.1"" 301 0
[11/Mar/2009 16:30:39] ""GET /text/5/ HTTP/1.1"" 500 71938

text/5/ works as in the Django Tutorial with polls/\d+ for a poll_id.
