Hi Ivan,
It is very likely that your problem is caused by one of these:
- `question` is not assigned to the template context
- `question` is assigned to the template context, but it has a wrong
value (e.g. `None`)
- the question has no `id` (it is not saved to the database yet).
This then results in this line:
`{% url 'polls:vote' question.id %}`
being something like
{% url 'polls:vote' "" %}
which does not match your URL pattern, because the pattern wants an
integer for the id.
I hope this helps!
René
