Question

我正在使用这个教程创建我的第一个django应用程序https://docs.djangoproject.com/en/dev/intro/tutorial04/。我已经完成了最后的任务，现在我有了这个错误，我不知道如何修复。我要去展示你我的整个计划，我会试着指出我认为我在进行这项民意调查时出错了。这个应用程序就像民意调查。它显示一个民意调查和一些选择，你必须投票。

这是我的错误

TemplateSyntaxError at /polls/1/
Caught NoReverseMatch while rendering: u'myapp' is not a registered namespaceRequest Method: GET 
Request URL: http://cat.pythonanywhere.com/polls/1/ 
Django Version: 1.3.5 
Exception Type: TemplateSyntaxError 
Exception Value: Caught NoReverseMatch while rendering: u'myapp' is not a registered namespace 
Exception Location: /usr/local/lib/python2.7/site-packages/django/template/defaulttags.py in render, line 450 
Python Executable: /usr/local/bin/uwsgi 

Template error

1 <h1>{{ poll.question }}</h1>

2  
3 {% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}

4  
5 <form action="{% url myapp:vote poll.id %}" method="post">

6 {% csrf_token %}

7 {% for choice in poll.choice_set.all %}

8     <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}" />

9     <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br />

10 {% endfor %}

11 <input type="submit" value="Vote" />

12 </form>

我认为错误隐藏在我的detail.html

中

<h1>{{ poll.question }}</h1>

{% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}

<form action="{% url myapp:vote poll.id %}" method="post">
{% csrf_token %}
{% for choice in poll.choice_set.all %}
    <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}" />
    <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br />
{% endfor %}
<input type="submit" value="Vote" />
</form>

我的Urls.py

from django.conf.urls.defaults import *
from mysite.myapp import views

urlpatterns = patterns('',

    url(r'^$', views.index, name='index'),
    url(r'^(?P<poll_id>\d+)/$', views.detail, name='detail'),
    url(r'^(?P<poll_id>\d+)/results/$', views.results, name='results'),
    url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),
)

我希望有人可以帮助我，因为我不知道如何修复此错误

Answer 1

在您的管理网址保存的主网址中，您的主urlconf轮询必须像这样注册该命名空间：

主 urls.py

 url (r'^poll/', include('poll.urls', namespace='poll')),

然后在孩子 urls.py

中

urlpatterns = patterns('poll.views',
    url(r'^$', index, name='index'),
    url(r'^(?P<poll_id>\d+)/$', 'detail', name='detail'),
    url(r'^(?P<poll_id>\d+)/results/$', 'results', name='results'),
    url(r'^(?P<poll_id>\d+)/vote/$', 'vote', name='vote'),
)

Answer 2

尝试在模板中将{% url myapp:vote poll.id %}更改为{% url vote poll.id %}

Answer 3

如果您的主要urls.py包含

url (r'^poll/', include('poll.urls'))

然后改为

url (r'^poll/', include('poll.urls', namespace='poll'))

这对我有用。
