Hi,
It looks like you are missing the poll in your context.
{% url 'detail' poll.id %} will try to match an url named detail with the
argument poll.id
However Django says it can't find a reverse for 'detail' with arguments ('',)
which means that you don't have a poll in your context (or the poll.id is
empty).
Double check that you already did the part
https://docs.djangoproject.com/en/1.5/intro/tutorial03/#raising-a-404-error
since the view is there and that there's no typo in the render(..., {'poll':
poll})
Regards,
Xavier,
Linovia.
