我是 Django 的新手。让 Django 1.4.2 在 Windows 7 上与 Python 2.7 一起工作。

我正在学习一个教程,我需要一个带有单选按钮的表单模板。选择一个按钮会发送数据,页面应该会询问您是否要“再次投票?”。此外,如果您没有选择按钮并提交表单,它应该会显示一条消息,要求您做出选择。

到目前为止,这是 HTML 表单:

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

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

<form action="{% url 'polls: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>

现在,当我键入时,http://localhost:8000/polls/1/我应该得到表单,但我得到以下错误消息:

NoReverseMatch at /polls/1/
u"'polls" is not a registered namespace

我将 polls 注册为命名空间,请参见下面的项目 urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^admin/', include(admin.site.urls)),
)

为了回答凯茜的好心请求,这里是投票网址:

from django.conf.urls import patterns, url

from polls import views

urlpatterns = patterns('',
    url(r'^$', views.index, name='index'),
    # ex: /polls/5/
    url(r'^(?P<poll_id>\d+)/$', views.detail, name='detail'),
    # ex: /polls/5/results/
    url(r'^(?P<poll_id>\d+)/results/$', views.results, name='results'),
    # ex: /polls/5/vote/
    url(r'^(?P<poll_id>\d+)/vote/$', views.vote, name='vote'),
)

..如果有帮助,我会在下面包含项目文件夹的网址:

from django.conf.urls import patterns, include, url
from django.contrib import admin

admin.autodiscover()

urlpatterns = patterns('',
    url(r'^polls/', include('polls.urls', namespace="polls")),
    url(r'^admin/', include(admin.site.urls)),
    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

)

我刚刚注意到浏览器上显示了以下错误消息(因为 Debug = True):

Error during template rendering

In template C:\Python27\Scripts\mysite\mytemplates\polls\index.html, error at line 4

u"'polls" is not a registered namespace
    {% if latest_poll_list %}
        <ul>
        {% for poll in latest_poll_list %}
            <li><a href="{% url 'polls:detail' poll.id %}">{{ poll.question }}</a></li>
        {% endfor %}
        </ul>
    {% else %}
        <p>No polls are available.</p>
    {% endif %} 

任何帮助使该表格正常运行将不胜感激!

urlpatterns = patterns('polls.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'),
)

{% url polls:detail poll.id %}

转到您的 settings.py 文件并检查您的模板加载器。您可能需要切换他们的顺序。

正确的顺序应该是:

TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',

)

希望这可以帮助。

尝试放在{% load url from future %}html 文件的顶部。它应该可以解决您的问题。
