我一直严格遵守了官方教程。 它位于这里：
https://docs.djangoproject.com/en/1.8/intro/tutorial03/
它已经准备好了，但突然我得到这个错误：
Reverse for 'detail' with arguments '(1,)' and keyword arguments '{}' not found. 0 pattern(s) tried: []
刚一发生，我改变了这一行：
<li><a href="/polls/{{ question.id }}/">{{ question.question_text }}</a></li>
这个新版本：
<li><a href="{% url 'detail' question.id %}">{{ question.question_text }}</a></li>
这行代码位于下面的index.html文件（我不知道如何显示在计算器正确indententation）：
{% if latest_question_list %}
<ul>
{% for question in latest_question_list %}
<li><a href="{% url 'detail' question.id %}">{{ question.question_text }}</a></li>
{% endfor %}
</ul>
{% else %}
<p>No polls are available.</p>
{% endif %}
这里是detail.html文件：
<h1>{{ question.question_text }}</h1>
<ul>
{% for choice in question.choice_set.all %}
<li>{{ choice.choice_text }}</li>
{% endfor %}
</ul>
这里是投票/ views.py文件：
from django.shortcuts import get_object_or_404, render
from .models import Question
def index(request):
latest_question_list = Question.objects.order_by('-pub_date')[:5]
context = {'latest_question_list': latest_question_list}
return render(request, 'polls/index.html', context)
def detail(request, question_id):
question = get_object_or_404(Question, pk=question_id)
return render(request, 'polls/detail.html', {'question': question})
def results(request, question_id):
response = "You're looking at the results of question %s."
return HttpResponse(response % question_id)
def vote(request, question_id):
return HttpResponse("You're voting on question %s." % question_id)
这里是投票/ urls.py文件：
from django.conf.urls import url
from . import views
urlpatterns = [
# ex: /polls/
url(r'^$', views.index, name='index'),
# ex: /polls/5/
url(r'^(?P<question_id>[0-9]+)/$', views.detail, name='detail'),
# ex: /polls/5/results/
url(r'^(?P<question_id>[0-9]+)/results/$', views.results, name='results'),
# ex: /polls/5/vote/
url(r'^(?P<question_id>[0-9]+)/vote/$', views.vote, name='vote'),
]
这里是的mysite / urls.py文件：
from django.conf.urls import include, url
from django.contrib import admin
urlpatterns = [
url(r'^polls/', include('polls.urls', namespace="polls")),
url(r'^admin/', include(admin.site.urls)),
]
这里是投票/ models.py文件：
import datetime
from django.db import models
from django.utils import timezone
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __str__(self): # __unicode__ on Python 2
return self.question_text
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
was_published_recently.admin_order_field = 'pub_date'
was_published_recently.boolean = True
was_published_recently.short_description = 'Published recently?'
class Choice(models.Model):
question = models.ForeignKey(Question)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
def __str__(self): # __unicode__ on Python 2
return self.choice_text
我该如何修正这个错误？ 任何意见，将不胜感激。 我是一个绝对的初学者使用Django和Python，虽然我有一点点的PHP经验。
谢谢。
