The chapter "Write a simple form" produces code with bad Choice.DoesNotExist handling

[tobami]

If you code the “polls/detail.html” template and the "mysite/polls/views.py" vote() function as in the tutorial, after voting without choosing an option, a DoesNotExist exception is raised and the poll voting form is redisplayed with a "You didn't select a choice." message. The problem is that you cannot try to vote a second time, because the redisplayed page is not "polls/1/" but "polls/1/vote/".

To reproduce:

• Complete tutorial 1 to 4 (for Django 1.0.2)
  
• go to "​http://localhost:8000/polls/1/"
  
• Click vote without selecting a Choice
  
• The page will be polls/1/vote/, not polls/1/ again
  
• Try to vote (or not, just click again vote)
  

It fails because it tries to access "polls/1/vote/vote/"

A possible solution would be to modify the form in poll_detail.html.

Replacing
<form action="vote/" method="post">

with
<form action="/polls/{{ object.id }}/vote/" method="post">

solves the problem, but it strikes me as a bit "hacky".

Is there another, cleaner way to solve it?
