1.)
Well I took the working *"class Poll"* version and changed much into *"class
Polly_bird"* instead to see if the underscore business was indeed causing
me this problem.
2.)
So I deleted the database.
3.)
And edited this file *"/mysite/polls/urls.py"*.
urlpatterns = patterns('',
...
...
# ex: /polls/5/
url(r'^(?P<pk>\d+)/$', views.DetailView.as_view(), name='detail'),
# ex: /polls/5/vote/
url(r'^(?P<polly_bird_id>\d+)/vote/$', views.vote, name='vote'),
)
4.)
And edited this file *"/mysite/polls/admin.py"*.
from polls.models import Polly_bird, Choice
...
...
class Polly_birdAdmin(admin.ModelAdmin):
...
...
admin.site.register(Polly_bird, Polly_birdAdmin)
5.)
And edited this file *"/mysite/polls/models.py"*.
class Polly_bird(models.Model):
...
...
class Choice(models.Model):
PollChoice = models.ForeignKey(Polly_bird)
...
...
6.)
And edited this file *"/mysite/polls/views.py"*.
from polls.models import Polly_bird, Choice
class IndexView(generic.ListView):
...
...
return Polly_bird.objects.order_by('-pub_date')[:5]
class DetailView(generic.DetailView):
model = Polly_bird
...
...
def vote(request, polly_bird_id):
p = get_object_or_404(Polly_bird, pk=polly_bird_id)
...
...
class ResultsView(generic.DetailView):
model = Polly_bird
...
...
7.)
Then I ran "python manage.py syncdb" to create the database tables from
scratch. After that I restarted the runserver.
8.)
Then I got the original error again, what line of code have I missed and in
which files?
Or why doesn't Django like it when I use underscore table naming convention?
http://localhost:8000/polls/1/
Exception Value:
Reverse for 'vote' with arguments '('',)' and keyword arguments '{}' not found.
Error during template rendering
/mysite/polls/templates/polls/*detail.html*, error at line *5*
...
...
5 <form action="{% url 'polls:vote' poll.id %}" method="post">
...
...
